Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

According to embodiments of the present invention, there is provided a prompting method, apparatus, electronic device, and storage medium for vehicle navigation, it should be noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is illustrated in the flowchart, in some cases, the steps illustrated or described may be performed in an order different from that illustrated herein.

In this embodiment, a method for prompting vehicle navigation is provided, fig. 1 is a flowchart of a method for prompting vehicle navigation according to an embodiment of the present invention, as shown in fig. 1, where the flowchart includes the following steps:

Step S101, detecting the display condition of the environment data inside the vehicle and the current navigation information of the vehicle.

The method provided by the embodiment of the application is applied to the control system of the vehicle, and the vehicle comprises a ① positioning system. And providing real-time position information of the vehicle. The position information is input into the navigation system so as to carry out real-time planning and judgment. This is the basis of the whole system, ensures that the position of the vehicle can be accurately perceived, and provides data support for navigation and path planning.

② A navigation system. And the function is to complete path planning and issue navigation reminding information. The method has the effects that an optimal driving path is planned according to the starting point, the finishing point, the real-time traffic information and the like of the vehicle, and related reminding information is transmitted to a driver through a terminal response system. The navigation system is the core for realizing the effective running of the vehicle, and determines the running route and direction of the vehicle.

③ The terminal responds to the system. Comprises a display, a loudspeaker and a vibration module. The display is used for displaying imaging equipment such as instruments, head-up display, a central control screen, a handrail screen and the like through various optical imaging technologies such as LCD, LED and the like, and providing visual navigation information such as maps, route indication and the like for a driver. And a loudspeaker, which is used as a sounding device and provides sound reminding, such as turning reminding, speed limit reminding and the like. The tone color of the sound and the azimuth of the sound field can be matched and changed according to the navigation guidance azimuth, so that the effect of augmented reality is achieved, and a driver is helped to better perceive the driving direction. The vibration module transmits the touch information to the driver through the vibration of the equipment in the vehicle, such as steering wheel vibration, seat belt pre-tightening and the like, so that the perception of the driver on navigation reminding is enhanced, and particularly under the condition that vision or hearing is disturbed, the driver is ensured to receive important navigation information in time.

In an embodiment of the present application, the environmental data inside the vehicle may include the status of the passenger, noise data, and the like. Specifically, an image of the passenger may be captured by a camera installed in the vehicle. The images are analyzed by using a visual algorithm to determine whether the passenger is at rest or speaking. For example, it may be determined by detecting the facial expression, eye state, and body posture of the passenger. Or a microphone may be used to collect sound inside the vehicle. The characteristics of the sound, such as voice activity detection, are analyzed by audio processing techniques to determine if the passenger is speaking. In addition, the noise level can be estimated by the intensity and frequency of the sound.

When the display condition of the current navigation information of the vehicle is detected, the display state of the navigation information can be obtained through communication with an electronic system of the vehicle. Or use image recognition techniques to directly monitor the on-board screen. The image of the screen is photographed by the camera, and then the image content is analyzed to determine whether the current navigation information is displayed on the in-vehicle screen.

Step S102, determining whether the environment data and/or the display condition hit the preset condition, and if the environment data and/or the display condition hit the preset condition, triggering the non-audible prompting mechanism to take effect.

In the embodiment of the application, the environment data (such as noise data in the vehicle, sound conditions of other devices in the vehicle, the state of passengers in the vehicle and the like) and/or the display conditions (such as whether navigation information is displayed on a display screen of the vehicle) are judged to see whether the environment data and the display conditions meet the preset conditions. And triggering a non-audible prompting mechanism to take effect if the environment data and/or the display condition meet the preset conditions. Navigation-related information is communicated to the driver, for example, by non-audible means such as vibration, flashing lights, etc., to ensure that the driver is still able to obtain the necessary navigation prompts under certain conditions, such as when the ambient noise is loud resulting in poor voice prompts. In addition, the voice prompt of the navigation system in the vehicle can be closed, so that the navigation system can not provide information such as route guidance through sound.

Step S103, acquiring the instant traffic situation data of the vehicle.

In the embodiment of the application, the instant traffic situation data of the vehicle comprises the running data of the vehicle and the path condition of the path where the vehicle is located. The running data of the vehicle includes a vehicle speed, acceleration, and the like. The vehicle speed can be obtained in real time through a speed sensor on the vehicle or equipment in communication with the vehicle. Acceleration can be measured by an acceleration sensor. The path conditions of the path along which the vehicle is located include whether to change a lane or turn, whether there is a safety risk, and the like.

Step S104, a prompt strategy corresponding to the instant traffic situation data is obtained based on a non-hearing prompt mechanism, and a driver is prompted according to the prompt strategy.

In the embodiment of the application, different reminding modes are set in the aspects of hearing, vision and touch. The imaging equipment is arranged at a plurality of positions of the vehicle by utilizing various optical imaging technologies in the visual aspect, so that comprehensive visual navigation information is provided for a driver, the comprehensive visual coverage is realized, and the driver can conveniently acquire navigation instructions under different visual angles. In the auditory aspect, through the sounding equipment of the loudspeaker, basic sound reminding is provided, the tone quality and the sound field azimuth of sound can be adjusted according to the navigation guidance azimuth, the augmented reality effect is realized, a driver can feel the change of the driving direction more intuitively in auditory sense, and the driving safety and convenience are improved. In the aspect of touch sense, the vibration of the in-vehicle equipment contacted with the body, such as steering wheel vibration, seat belt pre-tightening and the like, is used for providing a tactile navigation prompt for a driver, increasing the channel of information transmission, further improving the perception capability of the driver on navigation information, being beneficial to reducing the distraction of the driver and improving the driving safety especially in a complex driving environment.

Based thereon, it may be determined that non-audible alert mechanisms include visual alert, tactile alert, and the like. The visual prompt comprises ① instrument panel display, wherein traffic situation information such as vehicle speed, vehicle distance, road congestion, front accident warning and the like is displayed on the vehicle instrument panel in a form of graphics, icons or numbers. ② HUD head-up display, namely, key traffic information is directly projected into the sight range of a driver, so that the driver does not need to look at an instrument panel in a low head, and distraction is reduced. The navigation screen displays information such as real-time traffic road conditions, route suggestions, estimated arrival time and the like through a screen of the vehicle-mounted navigation system. ③ Atmosphere lamp-different color indicator lamps are used to indicate different traffic conditions, e.g. green for clear, yellow for light congestion and red for severe congestion.

And the touch prompt is ①, namely the steering wheel vibrates, and when the driver needs to change the road or turn, the steering wheel generates slight vibration to remind the driver of paying attention. ② Seat vibration-the seat may generate vibration according to traffic conditions, for example, when the vehicle deviates from the lane or approaches other vehicles, by which the driver is alerted. ③ The seat belt pretensions the seat belt as a tactile cue means, for example to alert the driver in case of overspeed of the vehicle.

Specifically, as shown in fig. 2, the telematics control unit (TELEMATICS CONTROL UNIT, TCAM) acquires positioning information of the vehicle using a Global Navigation Satellite System (GNSS). The navigation module receives the real-time positioning information from the TCAM and judges whether the reminding is needed according to preset conditions. If reminding is needed, the navigation module sends out corresponding signals. When a reminder is needed, a signal is sent to the Display Human-machine interface (Display Human MACHINE INTERFACE, DHU). After receiving the Display signal, the DHU presents the displayed reminding information on a Head-Up Display (HUD), a meter and other Display screens in other positions, so that a driver can intuitively see the relevant reminding content.

The sound signal will also be sent to the DHU. After the DHU converts the sound signals, the sound signals are sent to a loudspeaker, so that sound reminding is achieved, and a driver acquires relevant information through hearing.

The vibration signals are sent to a power steering control module (Power Steering Control Module, PSCM), a seat motor drive (Seat Motor Driver, SMD), and a Supplemental restraint system (Supplemental RESTRAINT SYSTEM, SRS), respectively. PSCM triggers steering wheel vibration according to received signal, SMD triggers seat vibrator vibration according to signal, SRS carries out the warning of safety belt pretension according to the signal. With these vibratory alerts, the driver can tactilely feel the relevant alert.

Fig. 3 is a flowchart of a prompting method for vehicle navigation according to an embodiment of the present invention, as shown in fig. 3, the flowchart includes the following steps:

In step S201, the display condition of the current navigation information of the vehicle is detected.

In the embodiment of the application, for the passenger state in the environment data, the image of the passenger can be captured through the camera installed in the vehicle. These images are then analyzed in depth using visual algorithms. Whether the passenger is in a resting state or is performing other activities, such as speaking, is determined by detecting the facial expression of the passenger, such as whether the passenger is relaxed or stressed, observing the eye state, such as whether the eyes are closed or blinking frequently, and analyzing the body posture, such as whether the passenger is resting on a seat or has other specific actions. In addition, for judging whether the passenger speaks, in addition to the above-described overall state judgment, the mouth motion of the passenger may be detected more specifically by a visual algorithm. If the mouth has obvious opening and closing actions and other characteristics such as facial expression, eye spirit and the like are combined, whether the passenger is speaking can be judged more accurately.

For noise data in the environmental data, a microphone may be used to collect sound inside the vehicle. Audio processing techniques may perform feature analysis on these sounds. By the voice activity detection technique, it is possible to determine whether or not the voice of the human being is contained in the sound, thereby determining whether or not the passenger is speaking. In addition, the intensity (volume) and frequency distribution of sound can be analyzed to evaluate the magnitude of noise in the vehicle. For example, continuous high intensity noise may mean that the interior environment of the vehicle is noisy.

For the display condition of the current navigation information of the vehicle, the information about whether the navigation information is displayed on the vehicle-mounted screen can be directly acquired by establishing communication connection with the electronic system. Or take an image of the on-vehicle screen with a camera. These image contents are then analyzed using an image recognition algorithm. It is determined whether the current navigation information is displayed on the on-vehicle screen by recognizing a specific icon, text, or map feature on the screen. The method is relatively visual, but may be affected by factors such as light, screen angle and the like, and an image recognition algorithm needs to be optimized to improve accuracy.

Step S202, determining whether the environment data and/or the display condition hit the preset condition, and if the environment data and/or the display condition hit the preset condition, triggering the non-audible prompting mechanism to take effect.

In the embodiment of the application, determining whether the environmental data and/or the display condition hit the preset condition comprises the steps of acquiring noise data and the passenger state in the vehicle from the environmental data, judging whether the noise data, the passenger state and/or the display condition hit the preset condition, wherein if the noise data is larger than the preset noise data, and/or the passenger state is in a rest state, and/or the display condition is not displayed, determining that the noise data hit the preset condition.

Specifically, whether the noise data, the passenger state and/or the display condition hit the preset condition is judged, wherein the specific content of the preset condition is that the noise data is considered to hit the preset condition if the noise data is larger than a preset noise data threshold value. Passenger status, if the passenger status is judged as resting status, it is also considered to hit the preset condition. Display condition, if the display condition is not displayed, the display condition is also determined to hit the preset condition.

As an example, there is a set of data with a noise data of 70 dB and a preset noise data threshold of 60 dB. The passenger state is detected as a resting state. The display is not shown. Judging according to preset conditions, wherein in the aspect of noise data, 70 dB is larger than 60 dB, and the noise data hits the preset conditions. In terms of the passenger state, the passenger state is a resting state, and the preset condition is hit. In the aspect of display conditions, the display conditions are not displayed and preset conditions are hit. In this example, the noise data, the passenger status, and the display conditions all hit the preset conditions.

Step S203, obtaining the real-time traffic situation data of the vehicle.

In the embodiment of the application, the instant traffic situation data of the vehicle is acquired, which comprises the following steps of A1-A3:

Step A1, detecting current driving data of the vehicle.

Specifically, data related to the travel of the vehicle is collected by various sensors and monitoring devices on the vehicle. Such data includes, but is not limited to, vehicle speed, acceleration, direction of travel, vehicle position, and the like. Wherein, the vehicle speed, namely the real-time running speed of the vehicle is obtained through a vehicle speed sensor. Acceleration, i.e. measuring the acceleration value of the vehicle during acceleration or deceleration. And the running direction of the vehicle is obtained through an electronic compass or a navigation system. Vehicle location, i.e., the current geographic location of the vehicle.

And step A2, acquiring the path condition of the current path of the vehicle based on the current navigation information.

In particular, the navigation system on the vehicle will be utilized to obtain detailed information about the current path of the vehicle, generally including road type, speed limit, road congestion, road construction, path geographic features, and so forth. The road type indicates that the road on which the vehicle is traveling is an expressway, an urban road, a rural road, or the like. The geographical characteristics of the path such as the grade of the road, curve, etc. By acquiring the path condition information, the vehicle running environment can be better known, and an important reference is provided for constructing the instant traffic situation data.

And step A3, constructing instant traffic situation data based on the driving data and the path condition.

Specifically, the running data (speed, acceleration, position, etc.) of the vehicle and the path conditions (road type, speed limit, congestion conditions, etc.) are integrated to form a unified data set. And taking the integrated data as the instant traffic situation data.

Step S204, a prompt strategy corresponding to the instant traffic situation data is obtained based on a non-hearing prompt mechanism, and a driver is prompted according to the prompt strategy.

In the embodiment of the application, a prompt strategy corresponding to the instant traffic situation data is obtained based on a non-auditory prompt mechanism, and a driver is prompted according to the prompt strategy, and the method comprises the following steps of:

and step B1, determining whether the vehicle currently needs to carry out path adjustment or not based on the path condition.

Specifically, the path condition acquired through the vehicle navigation system can determine whether the vehicle deviates from a predetermined route, whether there is an obstacle in front, a road condition change, or the like. By analyzing and processing the information, whether the vehicle currently needs to perform path adjustment or not can be judged. If the driving path of the vehicle is normal and no condition that adjustment is required occurs, the flow will not enter the subsequent steps. If it is determined that path adjustment is required, the next step is entered.

And step B2, if the current need of path adjustment is determined, determining the adjustment direction and the adjustment amplitude of the path adjustment.

Specifically, if it is determined that path adjustment is required, the direction and magnitude of the adjustment are further determined. The adjustment direction may be left or right, and the magnitude of the angle of adjustment. The magnitude of the adjustment then indicates how much change in the direction of travel of the vehicle is required, such as a slight adjustment or a greater magnitude of steering. This information will be used as a basis for subsequent operations.

And B3, determining a vibration area of a steering wheel in the vehicle according to the adjustment direction, and determining a target light prompting device which is in the same direction as the adjustment direction from a plurality of light prompting devices in the vehicle.

Specifically, according to the determined adjustment direction, the vibration area on the steering wheel is determined accordingly. For example, if it is desired to adjust the direction to the left, the left area of the steering wheel will be determined as the vibration area. Meanwhile, from a plurality of light prompting devices in the vehicle, the device with the same adjusting direction is selected as the target light prompting device. For example, if left adjustment is desired, the light prompting device on the left side of the vehicle will be selected.

And step B4, determining vibration equipment corresponding to the vibration area, and obtaining vibration times corresponding to the adjustment amplitude.

Specifically, after the vibration area is determined, the vibration device corresponding to the area is determined. These vibration devices are mounted inside the steering wheel for transmitting vibration signals to the driver. Meanwhile, according to the determined adjustment amplitude, the corresponding vibration times are calculated. The larger the adjustment amplitude, the more the number of shocks is, so as to more strongly inform the driver of the adjustment operation that needs to be performed.

And B5, controlling the vibration equipment to perform vibration operation on the steering wheel according to the vibration times, and controlling the target lamplight prompting equipment to flash according to the preset frequency.

Specifically, the system controls the vibration device to perform vibration operation on the corresponding area of the steering wheel according to the calculated vibration times so as to remind a driver of performing direction adjustment. Meanwhile, the system can control the target lamplight prompting device to flash according to the preset frequency, so that the prompting effect is further enhanced. By the mode, a driver can sense the path adjustment information required to be carried out through two modes of touch sense (steering wheel vibration) and vision (lamplight flickering) at the same time, so that the driver can respond more timely and accurately, and the safety and stability of vehicle running are ensured.

As one example, a deviation of a current travel path of the vehicle from a preset path is analyzed. If the vehicle is found to deviate from the preset path to a certain extent, determining that the vehicle currently needs to carry out path adjustment. Further analysis determines that the vehicle needs to be adjusted to the left by a certain angle. At this time, the adjustment direction of the path adjustment is left, and the adjustment range is a specific angle value. And determining the left area of the steering wheel in the vehicle as a vibration area according to the left adjustment direction. Meanwhile, from among a plurality of light prompting devices (e.g., a headlight, a rear lamp, an in-vehicle instrument panel lamp, etc.) in the vehicle, a turn lamp located on the left side of the vehicle is determined as a target light prompting device in the same direction as the adjustment direction. And finding vibration equipment corresponding to the vibration area on the left side of the steering wheel, and determining corresponding vibration times according to the angle value corresponding to the adjustment amplitude. And controlling the vibration equipment to perform vibration operation on the left side area of the steering wheel according to the vibration times so as to remind a driver of adjusting the direction leftwards. Meanwhile, the steering lamp on the left side of the vehicle is controlled to flash according to the preset frequency, so that the prompt of left adjustment is further enhanced.

The method provided by the embodiment of the application determines whether the path adjustment is needed according to the path condition, so that the vehicle can better adapt to different road conditions and running requirements, and the flexibility and adaptability of path planning are improved. And secondly, by determining the adjustment direction and the adjustment amplitude of the path adjustment, clear adjustment information is provided for a driver, so that more accurate path correction is realized, and the accuracy and the safety of running are improved. Visual direction indication is provided for a driver through a vibration area of the steering wheel and target light prompt equipment in the same direction. The combination of vibration and light cues can more effectively draw the attention of the driver, making it easier to understand and respond to adjustment needs.

In one embodiment of the application, a prompt strategy corresponding to the instant traffic situation data is obtained based on a non-auditory prompt mechanism, and a driver is prompted according to the prompt strategy, and the method comprises the following steps of C1-C4:

And step C1, acquiring the running speed of the vehicle based on the running data, and acquiring a speed limit value corresponding to the current running path.

Specifically, the current running speed of the vehicle is extracted from the running data of the vehicle. Meanwhile, the speed limit value corresponding to the current running path of the vehicle is obtained through a vehicle navigation system or other map data sources.

And C2, if the running speed exceeds the speed limit value, determining the ratio of the part of the running speed exceeding the speed limit value to the speed limit value.

Specifically, if the running speed of the vehicle exceeds the speed limit value of the current running path, a value is calculated in which the running speed exceeds the speed limit value. This excess value is then divided by the speed limit value to obtain a ratio. For example, if the speed limit value is 60 km/h and the running speed of the vehicle is 70 km/h, the excess is 10 km/h, and the ratio is 10/60=1/6.

And C3, inquiring a ratio range in which the ratio falls, and determining a prompt color corresponding to the ratio range.

Specifically, some ratio ranges are preset, and a prompt color is allocated to each ratio range. When the ratio of the travel speed exceeding the speed limit value is calculated, the ratio is compared with a set ratio range to determine which range it falls within. And then, carrying out subsequent operation according to the prompt color corresponding to the ratio range. For example, the ratio is set to be between 0 and 0.2 for green, between 0.2 and 0.4 for yellow, and 0.4 and above for red.

And C4, controlling light prompting equipment in the vehicle to prompt according to the prompting color, and controlling the safety belt at the main driving position to execute pre-tightening operation.

Specifically, according to the determined prompt color, the light prompt device in the vehicle is controlled to display the corresponding color. For example, if the alert color is red, the light alert device in the vehicle will emit red light. Meanwhile, the safety belt at the main driving position is controlled to execute pre-tightening operation so as to remind a driver of paying attention to overspeed conditions and enhance safety.

As one example, first, a travel speed is extracted from travel data of a vehicle. The navigation system or map data of the vehicle provides speed limit value information corresponding to the current travel path. Next, the acquired travel speed is compared with the speed limit value. If the running speed exceeds the speed limit value, calculating the ratio of the part of the running speed exceeding the speed limit value to the speed limit value, wherein the calculation formula is that the ratio= (the running speed limit value)/the speed limit value. Then, a plurality of preset ratio ranges are obtained, and corresponding prompt colors are set for each ratio range. For example, the ratio is between 0 and 0.2, and the prompt color is yellow. The ratio is between 0.2 and 0.5, and the prompt color is orange. The ratio is greater than 0.5, and the prompt color is red. Inquiring the range of the ratio which the calculated ratio falls into according to the calculated ratio, and determining the corresponding prompt color. And after the lamplight prompt equipment in the vehicle receives the prompt color information, lamplight prompt is carried out according to the corresponding color. The light prompting device emits yellow light if the prompting color is yellow, orange light if the prompting color is orange, and red light if the prompting color is red.

According to the method provided by the embodiment of the application, the running speed and the speed limit value of the vehicle are obtained in real time, and the overspeed condition is monitored and prompted, so that a driver can be timely reminded of paying attention to the speed, and the traffic accident risk caused by overspeed is reduced. When the running speed exceeds the speed limit value, the safety belt at the main driving position is controlled to execute the pre-tightening operation, so that the safety of a driver in an emergency situation is improved. And then determining the ratio of the part of the running speed exceeding the speed limit value to the speed limit value, and determining the prompt color according to the ratio range, wherein the visual feedback mode can enable a driver to more clearly judge the overspeed degree, and provides a personalized and easily perceived warning mode for the driver. In addition, timely overspeed prompt and safety belt pre-tightening operation can help drivers take measures before potential danger occurs, and the severity of accidents is reduced.

In one embodiment of the application, a prompt strategy corresponding to the instant traffic situation data is obtained based on a non-auditory prompt mechanism, and a driver is prompted according to the prompt strategy, and the method comprises the following steps D1-D4:

And step D1, determining whether a safety prompt road section exists in front of the vehicle based on the path condition.

Specifically, whether a road section needing to be subjected to safety prompt exists in front of the vehicle or not is judged according to the current running path of the vehicle and navigation information. The safety prompting road sections comprise sharp turns, steep slopes, accident-prone areas, construction road sections, crosswinds, railway road openings, continuous curved roads, continuous downslopes, road narrowing, easy-to-slide road sections, reverse curves and the like.

Step D2, if a safety prompt road section exists in front of the vehicle, determining the distance change condition between the vehicle and a maneuvering point of the safety prompt road section, and determining the remaining time of the vehicle reaching the maneuvering point and the remaining time change condition of the vehicle reaching the maneuvering point according to the running speed;

Specifically, if it is determined that a safety-promoting section exists in front of the vehicle, some relevant parameters are further calculated. First, a distance change condition between the vehicle and a mechanical point (e.g., a start point of a sharp turn, a start point of a steep slope, etc.) of the safety-presenting road segment is determined. This can be done by monitoring the position and direction of travel of the vehicle in real time by sensors on the vehicle (such as radar, cameras, etc.), and calculating the change in distance between the vehicle and the maneuver point in combination with the map information. Secondly, according to the running speed and the current position of the vehicle, the remaining time of the vehicle reaching the driving point according to the current speed is calculated. This remaining time may help drivers better understand their time urgency from the hazard area. Finally, the change condition of the remaining time of the vehicle reaching the mechanical point is calculated. This means that the trend of the remaining time is constantly monitored, such as whether the remaining time is gradually decreasing, what the rate of decrease is, etc. Such information may reflect changes in the state of travel of the vehicle and the proximity to the maneuver point.

Step D3, determining corresponding seat vibration frequency according to the distance change condition, or determining corresponding seat vibration frequency according to the residual time, or determining corresponding seat vibration frequency according to the residual change condition;

Specifically, the corresponding seat vibration frequency is determined according to the calculated distance change condition, the remaining time or the remaining time change condition. Specifically, a corresponding rule may be preset to correlate the distance change condition, the remaining time, or the remaining time change condition with the seat vibration frequency. For example, if the distance between the vehicle and the maneuver point is decreasing rapidly, or the remaining time for the vehicle to reach the maneuver point is short, the system may select a higher seat vibration frequency to more strongly alert the driver to safety. Conversely, if the distance is changing more slowly, or the remaining time is longer, the system may select a lower seat vibration frequency as a milder cue. By adjusting the seat vibration frequency according to different conditions, safety information can be more effectively transmitted to the driver, and the driver is helped to respond better.

For example, it is set that when the distance between the vehicle and the maneuver point is rapidly shortened from 100 meters to 20 meters in 10 seconds, or the remaining time for the vehicle to reach the maneuver point is less than 5 seconds, the system will select a higher seat vibration frequency of 10Hz to more strongly alert the driver to safety. Conversely, if the distance is slowly shortened from 100 meters to 80 meters in 30 seconds, or the remaining time is greater than 15 seconds, the system may select a lower seat vibration frequency of 2Hz as a milder cue. By adjusting the seat vibration frequency according to different conditions, the system can more effectively communicate safety information to the driver, helping the driver react better.

And D4, controlling a vibrator installed on the main driving seat to perform vibration operation on the main driving seat according to the seat vibration frequency.

Specifically, the determined seat vibration frequency is sent to a vibrator mounted on the main driving seat, and the vibrator is controlled to perform vibration operation on the main driving seat according to the frequency. Thus, the driver can feel the safety prompt through the vibration of the seat, so that the driver is more focused and the driving safety is improved.

As one example, if a sharp turn road segment 2 km ahead is detected, a safety cue road segment is determined to be present ahead of the vehicle. Once it is determined that a safety-alert section exists ahead, a change in distance between the vehicle and the maneuver point (e.g., the point at which a sharp turn begins) of the safety-alert section is calculated. Assuming that the current speed of the vehicle is 60 km/h and there is 2 km from the maneuver point, the remaining time for the vehicle to reach the maneuver point at the current speed is 2 minutes. At the same time, the change of the remaining time is continuously monitored. The corresponding seat vibration frequency is then determined based on the change in distance. For example, as the vehicle gets closer to the motor point, the vibration frequency gradually increases. Or the seat vibration frequency is determined based on the remaining time, such as the lower the remaining time, the higher the vibration frequency. Or according to the change condition of the residual time, if the reduction speed of the residual time is increased, the vibration frequency is correspondingly increased. And finally, controlling a vibrator arranged on the main driving seat to perform vibration operation on the main driving seat according to the determined seat vibration frequency. As the vehicle gets closer to the maneuver point of the tight turn section, the vibration of the primary driver's seat will gradually increase to alert the driver to the safety.

The method provided by the embodiment of the application can intuitively transmit the road safety information to the driver by determining whether the safety prompt road section exists in front of the vehicle and determining the vibration frequency of the seat according to the related conditions to execute the vibration operation on the main driving seat. The touch prompt can draw the attention of a driver, so that the driver is more alert and reacts in time, and the driving safety is improved. Compared with the traditional visual or audible prompt, the seat vibration tactile feedback mode can enable a driver to feel potential safety risks more directly without dispersing visual attention of the driver. This approach may more effectively alert the driver, especially in complex traffic environments or when the driver is not focused. In addition, the vibration frequency of the seat is determined according to the change condition of the distance between the vehicle and the motor point of the safety prompt road section, the residual time of the vehicle reaching the motor point and the change condition of the residual time, so that a personalized prompt mode is realized. Different conditions correspond to different vibration frequencies, so that a driver can know the emergency degree of the road condition more accurately.

In an embodiment of the present application, after prompting the driver according to the prompting policy, as shown in fig. 4, the method further includes:

step S301, at least one feedback information of the driver on the prompt strategy is obtained.

In the embodiment of the application, the purpose of acquiring the feedback information of the driver on the prompt strategy is to collect the response and the opinion of the driver on the implemented prompt strategy. Feedback information may be obtained in a variety of ways, such as by using a voice interactive system to allow drivers to directly dictate their feelings and advice on the prompting strategies. Or observe the behavior and reaction of the driver, for example, whether to operate according to the prompt, whether to present impatience to the prompt, etc., and take these observations as feedback information.

Step S302, data analysis is carried out on the feedback information, and distribution conditions of different feedback types are obtained.

In the embodiment of the application, after feedback information of a driver is collected, the information needs to be arranged and analyzed. Feedback information may be divided into different categories, for example, that drivers consider a prompt strategy helpful to their driving and would like to continue to use. Or the driver considers the prompt strategy to be problematic, such as prompting too frequently, inaccurately or not clearly, etc. Or the driver proposes an improvement suggestion to the reminder strategy, such as a way in which it is desirable to add certain functions or adjust the reminder. By classifying and counting the feedback information, the distribution situation of different feedback types, such as satisfactory proportion, unsatisfactory proportion, suggested proportion and the like, can be obtained.

Step S303, determining the optimized content of the prompt strategy according to the distribution conditions of different feedback types.

In the embodiment of the application, according to the obtained distribution condition of the feedback types, the aspect of prompting strategy to be optimized can be determined. For example, if the ratio of dissatisfaction is high, careful analysis of the cause of the dissatisfaction is required and improvements are made to these problems. For example, if the driver thinks the prompts are too frequent, the frequency of the prompts may be considered to be adjusted, and if the proportion of the proposed suggestions is high, the driver's suggestions need to be carefully studied and a reasonable fraction thereof included in the optimization. For example, if the driver suggests adding certain functions, the feasibility and practicality of these functions may be assessed and added where possible.

And step S304, optimizing the prompt strategy according to the optimized content, and storing the optimized prompt strategy.

In the embodiment of the application, after the optimized content of the prompt strategy is determined, the prompt strategy is required to be modified and perfected correspondingly. Such as adjustments to the hinting algorithm, modifications to the hinting content, control of the hinting frequency, etc. After the optimization is completed, the optimized prompt strategy needs to be stored so as to be used in practical application. Meanwhile, the optimized prompt strategy can be tested and verified, so that the expected effect can be ensured.

For example, a prompt strategy for determining the vibration frequency of the seat according to factors such as the change of the distance between the vehicle and the mechanical point has been implemented for a while. There is now a need to obtain driver feedback information on the prompting strategy. Firstly, at least one feedback information of a driver on a prompt strategy is obtained through an interaction interface or a sensor in the vehicle. For example, the driver may select the perception of the prompt via a button, such as "too strong", "just enough", "not obvious enough", etc. And then, carrying out data analysis on the feedback information to obtain the distribution conditions of different feedback types. For example, it was found by analysis that 30% of drivers considered too strong a prompt, 50% of drivers considered appropriate, and 20% of drivers considered less obvious. And then, determining the optimized content of the prompt strategy according to the distribution conditions of different feedback types. In this example, since more drivers consider the cues to be too strong, it may be considered appropriate to reduce the seat vibration frequency to adjust the intensity of the cues.

According to the method provided by the embodiment of the application, the actual demand and the feeling of the driver can be known by acquiring the feedback information of the driver on the prompt strategy, so that the optimization is performed pertinently, and the experience of the driver when using the related prompt function is improved. And carrying out data analysis on the feedback information, and determining the optimized content of the prompt strategy according to objective data. The prompt strategy can be better adapted to the requirements and preferences of different drivers by optimizing according to the distribution conditions of different feedback types, personalized service is realized, and the practicability and effectiveness of the prompt strategy are improved. And optimizing and storing the prompt strategy according to the optimized content to form a continuously improved cycle. The prompt strategy is beneficial to continuously improving the performance and effect of the prompt strategy, so that the prompt strategy can better meet the requirements and expectations of drivers and adapt to the continuously-changing driving environment and user requirements.
