step S10: and acquiring the starting time of the blind spot monitoring system.
It should be noted that, the execution main body of the embodiment may be a device having a vehicle identification alarm recognition function, and the device may be a vehicle-mounted computer, a tablet computer, a mobile phone, a notebook computer, and the like, and the embodiment takes the vehicle-mounted computer as an illustration, and the embodiment and the following embodiments take the vehicle-mounted computer as an example to describe the vehicle identification alarm method of the present invention. .
It should be understood that because there is the vision blind area in the automobile rearview mirror, can't see the vehicle of blind area before changing the way, if there is overtaking vehicle in the blind area, change the way and easily take place the collision accident this moment promptly, blind spot monitoring system is the high-tech configuration of a safe class on the car, and the main function is to clear away the rearview mirror blind area, surveys the overtaking vehicle in the rearview mirror blind area of vehicle both sides through microwave radar, in order reminding the driver to avoid taking place the accident because the rearview mirror blind area at the change way in-process. When can be through the millimeter wave radar monitoring vehicle in vehicle rear both sides when traveling, control the vehicle in side rear and dead-back, if there is the vehicle in the blind area (0-10 m behind the car), then send alarm information, remind the driver, blind spot monitoring system also can obtain all ring edge border object information according to the radar of backing a car simultaneously, for example: stumps, road stumps and flower beds at the lateral rear part of the vehicle, children playing behind the vehicle and the like.
It is understood that the startup duration may refer to the duration of the initial startup of the blind spot monitoring system in the vehicle system, for example: the initial startup time of the blind spot monitoring system is 3 seconds, 5 seconds, 9 seconds and the like, and can also be the preheating time before the activation of the blind spot monitoring system.
In specific implementation, the vehicle-mounted computer can obtain the starting-up time of the blind spot monitoring system through a counter in the vehicle-mounted system.
Step S20: and when the starting time exceeds the preset time, acquiring target radar information, and determining tracking target information according to the radar information.
It should be noted that the preset time length may be a time length set by human operation, or a time length set according to vehicle parameter configuration.
The target radar information can be understood as radar information after a blind spot monitoring system is filtered once after being started for the first time, wherein the filtering is to filter more stray interference signals in the radar information, and the radar information after the stray interference signals are filtered is used as the target radar information.
It should be understood that the tracking target information may refer to information such as a relative speed, a relative position, a relative distance, and a relative angle of the vehicle under test.
In the specific implementation, when the vehicle-mounted computer recognizes that the startup duration exceeds the preset duration, for example: the preset time length set at present is 3 seconds, and the starting time length is 4 seconds, namely, the vehicle-mounted computer can output two paths of intermediate frequency signals I and Q after the signals reflected by the target to be detected are received by the millimeter wave radar receiving array antenna and are amplified by the amplifier and the like. I. The Q signal is amplified by the filter circuit and the operational amplifier respectively, and then converted into a digital signal for analysis. Through the digital signal, the frequency and amplitude information of the I, Q signal can be obtained, the speed, distance and angle information of a target can be further analyzed, and more stray interference signals exist in the I, Q signal generated by receiving and need to be filtered out through a filter circuit. And taking the filtered information as target radar information. And determining information such as relative speed, relative position, relative distance and relative angle between the detected vehicle and the self vehicle according to the target radar information.
Step S30: and judging whether first relatively static target information exists according to the tracking target information, and if the first relatively static target information exists, giving an alarm according to first alarm information.
It should be noted that the tracking target may be information generated by the vehicle under test, such as: the first relative stationary target information may be information generated when the vehicle to be measured and the own vehicle are kept relatively stationary. For example: the relative stationary information may be determined from information such as a relative distance, a relative speed, a relative angle, and a relative position between the vehicle under test and the own vehicle.
It can be understood that the first alarm information may refer to alarm information generated by the vehicle-mounted computer according to a current relative stationary state when the vehicle and the detected vehicle are kept relatively stationary, and the alarm information may include an alarm code, an information category, and a real serial number. Time when the information occurs, controller number, and the like.
It should be understood that the alarm prompt may be prompt information generated according to the first alarm information, and the alarm prompt may prompt a warning display that the driver may have an abnormal condition on a screen of the vehicle-mounted display, or may prompt the driver through voice broadcast.
In specific implementation, the vehicle-mounted computer can judge whether first relatively static target information exists according to the tracking target information, and if the first relatively static target information exists, alarm prompt is carried out according to first alarm information. For example: the vehicle-mounted computer acquires information such as speed, distance and angle of a detected vehicle contained in the tracking target information from the radar information, judges whether relative static information exists between the detected vehicle and the vehicle according to the driving information of the vehicle, and can determine first alarm information according to the relative distance information contained in the current relative static information when the relative static information exists, such as: when the current relative distance is in a small range, the vehicle-mounted computer sends a primary alarm code to generate a primary alarm signal, and the alarm system reminds a driver through voice prompt according to the primary alarm signal.
According to the embodiment, the method and the device, the starting time of the blind spot monitoring system is obtained, the target radar information is obtained when the starting time exceeds the preset time, the tracking target information is determined according to the radar information, whether the first relatively static target information exists or not is judged according to the tracking target information, if the first relatively static target information exists, the alarm prompt is carried out according to the first alarm information, and because whether the relatively static target information exists or not is judged according to the starting time and the radar information, the interference information in the radar information is directly filtered, in comparison with the prior art, the radar information is screened through the starting time of the blind spot monitoring system to obtain the relatively static target information, the alarm prompt is carried out, so that the effective identification of the relatively static target is realized, and the performance of a driving system is improved.
Referring to fig. 3, fig. 3 is a flowchart illustrating a second embodiment of the vehicle identification warning method according to the present invention, and the second embodiment of the vehicle identification warning method according to the present invention is proposed based on the first embodiment illustrated in fig. 2.
In this embodiment, the step S20 includes:
step S201: and when the starting-up time exceeds the preset time, filtering clutter information in the radar information, and acquiring target radar information.
The clutter information may refer to radar scattered echo information of other objects (e.g., a detected vehicle) in the radar information, or may refer to echo information of a relatively stationary target.
It is understood that the target radar information may refer to radar information that filters out radar-scattered echoes of objects other than the object under test. The target radar information can also be radar information obtained after the clutter information is filtered from the historical radar information once when the self-vehicle blind spot monitoring system is started for the first time and reaches the preset time.
In specific implementation, when the starting-up time exceeds the preset time, filtering clutter information in radar information, and acquiring target radar information, for example: and after the vehicle-mounted computer is started for 3 seconds, activating a blind spot monitoring system, filtering clutter information in the radar information generated within three seconds, and acquiring target radar information.
Step S202: and judging whether a tracking target enters an alarm area or not according to the target radar information, and if so, determining tracking target information.
It should be noted that the alarm area may be an area for alarming when an object is approaching in the front, rear, left, and right 360 ° blind areas of the vehicle, and the alarm area range may be a distance manually set or may be a parameter configured by the vehicle.
In the specific implementation, objects around a vehicle body are tracked in the running process of the vehicle, and tracking target information is acquired after a target object enters a blind area.
Further, in order to accurately identify clutter information in the radar information, the duration of a timer can be obtained; and when the time length of the timer is within a preset time length range, stopping filtering clutter information in the radar information, and acquiring first identification information.
It should be noted that the timer duration may be a timing duration of a timing device installed in the vehicle-mounted system; the timing device starts timing after the blind spot monitoring system is activated, and the preset duration range can be set according to the habit of a driver or the configuration parameters of the vehicle. For example: the preset time period range may be set to 0.5s-1.0 s.
It will be appreciated that the first identification information may be identification information comprising clutter information from which the first relatively stationary target information may be determined. After the first identification information can be processed by noise, according to the identification module in the vehicle-mounted system, the characteristic information contained in the first identification information, such as: the method comprises the steps of identifying size, contrast, density, linear characteristics and the like, extracting characteristics of a target area to form a characteristic vector, matching the characteristic vector with preset characteristics stored in a database to obtain a matching result, and determining first identification information according to the matching result.
It is to be understood that the relative stationary object information may be information determined from relative speed information, relative distance information, relative angle information between the own vehicle and the measured object.
In the specific implementation, in order to more accurately identify the target object within the blind area range and prevent missing report, the time length of the timer can be obtained; and when the time length of the timer is within a preset time length range, stopping filtering clutter information in the radar information, and acquiring first identification information.
Further, in order to enable the driver to accurately obtain the danger prompt, whether the first relatively static target information exists or not can be judged according to the first identification information, and a first judgment result is obtained. Determining a first alarm type according to the first judgment result; and searching corresponding first alarm information from a first preset mapping table according to the first alarm type, and giving an alarm prompt according to the first alarm information.
It should be noted that the first determination result is a result of determining whether a target object exists in the blind area range according to the first relative stationary target information. The first preset mapping table may be a corresponding relationship table between the first alarm type and the first alarm information.
It will be appreciated that the first warning type may be a warning type determined from the driving situation, for example: when the vehicle runs on the expressway, the ringtone playing type can be adopted, and the ringtone alarm signal information corresponding to the ringtone playing type can be used.
In specific implementation, the vehicle-mounted computer can judge whether the first relatively static target information exists according to the first identification information, obtain a first judgment result and associate with an alarm system in the vehicle-mounted system according to the first judgment result.
Further, in order to clearly prompt the driver for the danger prompt, the first alarm type includes an emergency alarm state and a warning release state; the alarm type may be determined to be an emergency alarm state when the first determination result indicates that the first relatively stationary object information exists; and when the first judgment result indicates that the first relative static target information does not exist, determining that the alarm type is in an alarm release state.
It should be noted that the emergency alarm state may refer to an alarm system sending an emergency alarm prompt when a relatively stationary object is identified, for example: and the vehicle-mounted computer carries out emergency alarm prompt according to the relative distance information contained in the first relative static target information, and when the relative distance is smaller and smaller, the vehicle-mounted computer controls the alarm system to send out emergency voice broadcast to prompt a driver.
It is to be understood that disarming the alert state may refer to disarming the pre-warning alert state when no relatively stationary target is identified.
In the concrete implementation, in the preset time duration, the target object can be acquiescent, and the early warning state is kept, if: and keeping the existence of a default target object within 0.5s, and keeping the early warning state. And stopping filtering clutter within 0.5s-1 s. If a relatively static target exists, the alarm state is kept, the timer is reset, the state is recovered, and clutter is filtered again; if the target object is not found, the alarm is closed, the timer is reset, the state is recovered, and clutter is filtered again.
In the embodiment, by obtaining the starting-up time of the blind spot monitoring system, when the starting-up time exceeds the preset time, clutter information in radar information is filtered, and target radar information is obtained; and judging whether a tracking target enters an alarm area or not according to the target radar information, if so, determining tracking target information, judging whether first relatively static target information exists or not according to the tracking target information, and if so, giving an alarm according to first alarm information. Because whether the tracking target enters the alarm area or not is judged according to the target radar information, compared with the prior art, clutter information is directly filtered to cause false alarm, the method and the device realize the identification of the relatively static target in the driving process, and identify the dangerous signal more accurately.
Referring to fig. 4, fig. 4 is a flowchart illustrating a third embodiment of the vehicle identification warning method according to the present invention, and the third embodiment of the vehicle identification warning method according to the present invention is proposed based on the first embodiment illustrated in fig. 2.
In the third embodiment, after step S30, the method further includes:
step S40: and when the starting-up time does not exceed the preset starting-up time, stopping filtering clutter information in the radar information, and obtaining second identification information.
Note that the second identification information may be identification information including clutter information. After the second identification information can be processed by noise, the second identification information is subjected to characteristic information contained in the second identification information according to an identification module in the vehicle-mounted system, such as: and identifying the size, the contrast, the density, the linear characteristics and the like, extracting the characteristics of the target area to form a characteristic vector, matching the characteristic vector with preset characteristics stored in a database to obtain a matching result, and determining second identification information according to the matching result.
In specific implementation, when the starting-up time length does not exceed the preset starting-up time length, filtering of clutter information in the radar information is stopped, and second identification information is obtained. For example: the preset starting-up time is 3S. The current startup duration is 2S, namely clutter information contained in the radar information is not filtered in 3S, the radar information is subjected to noise processing, the characteristic information contained in the radar information is identified according to an identification module contained in a vehicle-mounted system, target characteristic information is obtained, the target characteristic information is matched with preset characteristics stored in a database according to the target characteristic information, a matching result is obtained, and second identification information is determined according to the matching result.
Step S50: and judging whether second relative static target information exists according to the second identification information, and obtaining a second judgment result.
It should be noted that the second relatively stationary target information may be already-existing relatively stationary target information around the vehicle body of the vehicle when the blind area monitoring system is just turned on.
It can be understood that the second judgment result is a result of judging whether the target object exists in the blind area range according to the second relative stationary target information.
In a specific implementation, the vehicle-mounted computer can judge whether the second relative stationary target information exists according to the second identification information, obtain a second judgment result, and associate with an alarm system in the vehicle-mounted system according to the second judgment result.
Step S60: and determining a second alarm type according to the second judgment result.
It should be noted that the second alarm type may be a type that alarms on objects around the vehicle body when the vehicle is just started, and may be broadcast by using a display screen.
In a specific implementation, the vehicle-mounted computer may select a second alarm mode according to a second judgment result, for example: when the vehicle is just started and target objects around the vehicle body are identified, if second relative static information exists, the driver can be prompted through voice broadcasting.
Step S70: and searching corresponding second alarm information from a second preset mapping table according to the second alarm type, and giving an alarm according to the second alarm information.
It should be noted that the second preset mapping table may refer to a corresponding relationship between the second alarm information and the second alarm type.
It will be appreciated that the second warning type may be a warning type determined from the driver's state, for example: when the driver is tired, the alarm sound with large decibel is adopted to prompt the driver, and the alarm information can be determined according to the alarm sound signal
In specific implementation, the vehicle-mounted computer can search corresponding second alarm information from a second preset mapping table according to the second alarm type, and carry out alarm prompting according to the second alarm information. For example;
further, in order to effectively identify a relatively stationary target and prompt a driver, the second alarm type includes an early-warning alarm state and a non-early-warning state, and the alarm type may be determined to be the early-warning alarm state when the second determination result indicates that the second relatively stationary target information exists; and when the second judgment result indicates that the second relatively static target information does not exist, determining that the alarm type is in a non-early-warning state.
In the implementation, when the vehicle-mounted computer determines that the relative static target exists at present according to the blind spot monitoring system, the vehicle-mounted computer enters an early warning state and gives an alarm, clutter is filtered after three seconds, and when the relative static target does not exist, the system does not give an alarm and starts to filter the clutter.
