S10: Obtain the current vehicle speed of the vehicle 100;

S20: When the current vehicle speed is less than or equal to the preset vehicle speed, detect whether there is a load on the seat 10 of the vehicle 100;

S30: When there is a load on the seat 10, control the seat 10 to execute a preset adjustment mode at a first speed V1;

S40: When there is no load on the seat 10, control the seat 10 to execute the preset adjustment mode at the second speed V2, the second speed V2 is greater than the first speed V1.

Please refer to FIG. 2 , the seat 10 provided by the embodiment of the present application includes a main body 11 , a sensor 12 , a two-speed motor 13 and a controller. The sensor 12 is connected to the main body 11 . The two-speed motor 13 is connected with the sensor 12 . The controller is connected with the main body 11 . The controller is used to implement the above-mentioned method for adjusting the seat 10 .

In other words, the controller is used to obtain the current vehicle speed of the vehicle 100; it is also used to detect whether there is a load on the seat 10 of the vehicle 100 when the current vehicle speed is less than or equal to the preset vehicle speed; it is also used to detect when there is a load on the seat 10 , for controlling the seat 10 to perform a preset adjustment mode at a first speed V1; and for controlling the seat 10 to perform a preset adjustment mode at a second speed V2 when there is no load on the seat 10, the second speed V2 being greater than the first speed V2 Speed V1.

Please refer to FIG. 2 and FIG. 3 , the vehicle 100 provided by the embodiment of the present application includes the above-mentioned seat 10 .

Referring to FIG. 4 , the control device 20 provided by the embodiment of the present application includes an acquisition module 21 , a detection module 22 , a first control module 23 and a second control module 24 . The obtaining module 21 is used for obtaining the current vehicle speed of the vehicle 100 . The detection module 22 is used to detect whether there is a load on the seat 10 of the vehicle 100 when the current vehicle speed is less than or equal to a preset vehicle speed. The first control module 23 is used for controlling the seat 10 to execute a preset adjustment mode at a first speed V1 when the seat 10 is loaded. The second control module 24 is used for controlling the seat 10 to execute a preset adjustment mode at a second speed V2 when there is no load on the seat 10 , and the second speed V2 is greater than the first speed V1 .

In this way, when there is no load on the seat 10, the seat 10 can be adjusted to the set state at a faster speed to reduce the waiting time, and when there is a load on the seat 10, the seat 10 can be adjusted at a slower speed. The adjustment is so that the occupants can accurately dock the seat 10 to the comfortable position they want, by intelligently distinguishing whether there is a load on the seat 10, and calling the corresponding running speed of the seat 10 to adjust the state of the seat 10 after distinguishing, Improve user experience.

Wherein, the controller of the seat 10 can perform information interaction with the vehicle 100 through the vehicle network signal, so that the controller of the seat 10 can obtain the current speed of the vehicle 100 synchronously.

In step S20 , the sensor 12 of the seat 10 can be used to detect whether there is a load on the seat 10 of the vehicle 100 , wherein the sensor 12 can be a pressure sensor, and the pressure sensor can be arranged on the cushion 112 of the seat 10 . The pressure sensor can be used to detect the weight on the seat 10. When the weight is greater than the preset weight, it can be determined that there is a load on the seat 10. When the weight is less than or equal to the preset weight, it can be determined that there is no load on the seat 10. In some embodiments, the sensor 12 can also be an infrared sensor, and the infrared sensor can be used to detect whether there is a load on the seat 10 . The type of sensor 12 is not restricted here.

In some embodiments, the seat 10 may further include a camera device, which may be used to acquire images on the seat 10 . After processing and analyzing the image, it can be determined whether there is a load on the seat 10 . Wherein, the load may be a person, an animal, or an object.

In step S30, when there is a load on the seat 10, the seat 10 is controlled to perform a preset adjustment mode at a slower speed, so that the passenger on the seat 10 can feel the current position of the seat 10 while adjusting the seat 10 Whether or not the angle is appropriate can facilitate the passengers on the seat 10 to accurately adjust the seat 10 to a position or angle that meets their own needs, so as to improve user experience.

Meanwhile, when the speed of the seat 10 is too fast during the execution of the preset adjustment mode, the passengers on the seat 10 may be injured. For example, when the seat 10 is unfolded rapidly, the occupant on the seat 10 will suddenly lean back, or when the seat 10 is folded rapidly, the user will be squeezed. Therefore, when the seat 10 is loaded, controlling the first speed V1 of the seat 10 to execute the preset adjustment mode can also ensure the safety of the passengers on the seat 10 .

Wherein, the value range of the first velocity V1 may be 1 cm/s˜3 cm/s, which is not limited here. Control the seat 10 to adjust the state of the seat 10 itself at the first speed V1, which can be to adjust the angle between the backrest 111 of the main body 11 and the seat cushion 112, such as folding or unfolding, etc., or to adjust the windshield of the seat 10 relative to the front. The position of the glass, such as forward or backward.

In step S40, when there is no load on the seat 10, the seat 10 is controlled to execute the preset adjustment mode at a faster speed, so that the seat 10 can quickly move to the set target position, thereby reducing the user's effort. waiting time. Wherein, the value range of the second velocity V2 may be 4 cm/s˜6 cm/s, which is not limited here.

In one embodiment, the preset vehicle speed is 5km/h. When the vehicle 100 is traveling on a congested road section at a speed of 4km/h, and the passenger in the co-pilot seat wants to adjust the seat 10 to a bed mode, the passenger can pass through the seat. The button on the chair 10 makes the backrest 111 of the seat 10 rotate backward at a speed of 2 cm/s until the backrest 111 stays at an angle that meets the passenger's needs. When the passenger in the co-pilot seat gets off the vehicle and the vehicle 100 is parked on the side of the road, in order to restore the state of the co-pilot seat 10, the driver can use the central control screen of the vehicle 100 to make the backrest 111 of the seat 10 move toward The front rotation makes the passenger seat 10 quickly return to the state before the last adjustment.

It should be noted that the above-mentioned examples and specific numerical values are for the convenience of describing the implementation of the present application, and should not be construed as limiting the protection scope of the present application.

Referring to Fig. 5, in some embodiments, the two-speed motor 13 may include a motor 131, a switch 132, a first terminal 133 and a second terminal 134, and when the motor 131 is working, the armature (rotor) simultaneously generates Back EMF, the direction of the motor 131 is opposite to the direction of the armature current. To rotate the motor 131, the applied voltage must overcome the effect of the back electromotive force. When the rotation speed of the motor 131 increases, the back electromotive force increases, and only when the applied voltage is equal to the back electromotive force, the rotation speed of the armature can be stable. Three brushes are used to change the number of coils connected in series between the positive and negative brushes to realize variable speed. Thus, the two-speed motor 13 can be used to control the seat 10 to execute the preset adjustment mode at the first speed V1 when there is a load on the seat 10; Two-speed V2 implements preset regulation mode.

When the switch 132 is connected to the first terminal 133 , current flows in through the first terminal 133 , and the motor 131 operates at a low speed, and when the switch 132 is connected to the second terminal 134 , the motor 131 operates at a high speed. Wherein, when the current flows in through the first terminal 133, the resistance value of the effective winding passing through is smaller than the effective winding passing through the current flowing in through the second terminal 134. Therefore, when the switch 132 is connected to the first terminal 133, the resistance of the motor 131 The operating speed is lower than the operating speed of the motor 131 when the switch 132 is connected to the second terminal 134 .

When the seat 10 is loaded, the switch 132 of the two-speed motor 13 is connected to the first terminal 133 to control the seat 10 to execute the preset adjustment mode at the first speed V1. When there is no load on the seat 10, the switch 132 of the two-speed motor 13 is connected to the second terminal 134, and the seat 10 is controlled to execute the preset adjustment mode at the second speed V2. It should be pointed out that when the seat 10 executes the preset adjustment mode at the first speed V1, the torque of the motor 131 is greater than that when the seat 10 executes the preset adjustment mode at the second speed V2. Since the passenger sits on the seat 10 with a heavy load, the torque requirement of the motor 131 is relatively large. Preferably, the torque of the motor 131 when the seat 10 is loaded is about twice that of the seat 10 when the seat 10 is unloaded.

In this way, after using the sensor 12 to determine whether there is a load on the seat 10, the two-speed motor 13 can call the corresponding working speed to adjust the state of the seat 10,

A two-speed motor 13 is used to support the realization of the adjustment method of the seat 10 . Compared with the related art, which uses a high-power single-speed seat drive motor to control the adjustment of the seat through PWM (pulse width modulation technology) voltage regulation, the two-speed motor 13 of the seat 10 provided by the embodiment of the present application The volume is smaller, the mass is smaller and the cost is lower, so that the vehicle 100 can be reduced in weight while reducing the cost.

It should be noted that, in some embodiments, when the current vehicle speed is greater than the preset vehicle speed, the control seat 10 executes the preset adjustment mode at the first speed V1. That is, when the current vehicle speed is too fast, regardless of whether there is a load on the seat 10 , the seat 10 is controlled to perform the preset adjustment mode at a slower rate, thereby ensuring safety in the vehicle 100 when the seat 10 is adjusted.

In some embodiments, the preset adjustment mode includes: adjusting the position of the seat 10 , and/or, adjusting the deployment angle of the seat 10 . In this way, the user can adjust the position of the seat 10 and adjust the deployment angle of the seat 10 according to actual needs.

Specifically, the main body 11 may include a seat cushion 112 and a backrest 111 connected to the seat cushion 112 , and the deployment angle of the seat 10 is the angle between the seat cushion 112 and the backrest 111 . Adjusting the position of the seat 10 refers to adjusting the distance of the seat 10 relative to the front window, and may also be adjusting the distance of the seat 10 relative to the floor, which is not limited here.

The preset adjustment mode may also include a passenger toilet in and out mode, a folding mode, a one-key bed forming mode, and a recovery mode, etc., which are not limited here. Exemplarily, the passenger in and out mode may refer to controlling the seat 10 to move a certain distance forward or backward relative to the front window. The folding mode means that the unfolding angle of the control seat 10 is reduced. The one-button bed formation mode refers to controlling the expansion angle of the seat 10 to increase. The recovery mode means that the state of the control seat 10 is restored to the state before the last adjustment or the initial state.

It should be pointed out that when there is no load on the seat 10 and the seat 10 is controlled to execute the preset adjustment mode at the second speed V2, the position and deployment angle of the seat 10 are preset, that is, the seat 10 can Automatic adjustment to a predetermined target position at a second speed V2. For example, the control seat 10 is moved backward by 5 cm, the control seat 10 is moved forward by 5 cm, the control seat 10 is unfolded to 135 degrees, the control seat 10 is folded to 95 degrees, etc., and the control seat 10 is restored to the initial state, etc., which will not be done here. limit.

Among them, the initial state can be set according to user habits. For example, the initial state is that the distance between the seat 10 and the central control screen is 10 cm, and the angle between the backrest 111 and the seat cushion 112 of the seat 10 is 95 degrees.

It should be noted that the above-mentioned examples and specific numerical values are for the convenience of describing the implementation of the present application, and should not be construed as limiting the protection scope of the present application.

When there is a load on the seat 10 and the seat 10 is controlled to execute the preset adjustment mode at the first speed V1, the position and deployment angle of the seat 10 are adjusted by the user in real time, and the user can feel the current seat while adjusting the seat 10. Whether the position and deployment angle of the chair 10 are appropriate, so that the seat 10 can be accurately adjusted to the state desired by the user. It should be pointed out that when the control seat 10 executes the preset adjustment mode at the first speed V1 or the second speed V2 , the first speed V1 and the second speed V2 refer to the speed of adjusting the position of the seat 10 . The speed of adjusting the unfolding angle of the seat 10 is the ratio of the first speed V1 or the second speed V2 to the height of the backrest 111 of the seat 10 .

Referring to FIG. 6, in some embodiments, before obtaining the current vehicle speed of the vehicle 100 (step S10), the method for adjusting the seat 10 includes:

S01: Receive adjustment instructions;

S02: Analyze the adjustment command to determine the preset adjustment mode of the seat 10 .

In some implementations, the control device 20 may further include an instruction module 25 for receiving an adjustment instruction and analyzing the adjustment instruction to determine a preset adjustment mode of the seat 10 .

In some embodiments, the controller is configured to receive adjustment commands and to analyze the adjustment commands to determine a preset adjustment mode for the seat 10 .

In this way, the user can issue a corresponding adjustment instruction, through which the preset adjustment mode of the seat 10 is determined, and the seat 10 is controlled to execute the preset adjustment mode so that the seat 10 can be adjusted to a state that meets the user's actual needs.

Specifically, the adjustment instruction can be issued by means of buttons on the seat 10, by a remote control device that can remotely control the status of the seat 10, by user voice, or by the central control screen of the vehicle 100, etc. This is not limited. The preset adjustment mode of the seat 10 may include, but not limited to, the seat 10 moves forward, backward, folded, unfolded, or restored to its original state.

In one embodiment, the passenger on the seat 10 presses the button on the seat 10 to control the seat 10 to move backward so as to get off, and the seat 10 moves backward at a speed of 1.5 cm/s. When the user reaches a position convenient for activities, the user releases the button so that the seat 10 stops moving backwards. In another embodiment, when there is no passenger on the No. 3 seat 10 of the vehicle 100, after the driver utters the voice "No. 3 seat 10 moves forward 3 cm", the No. 3 seat 10 moves forward at 0.6 cm/s for 5 seconds. Stop exercising.

It should be noted that the above-mentioned examples and specific numerical values are for the convenience of describing the implementation of the present application, and should not be construed as limiting the protection scope of the present application.

Referring to FIG. 7, in some embodiments, the method for adjusting the seat 10 includes:

S50: Obtain the distance between the seat 10 and the target object during the execution of the preset adjustment mode, and the target object is located in the movement direction of the seat 10;

S60: When the distance is less than the preset distance, the control seat 10 stops executing the preset adjustment mode.

In some embodiments, the first control module 23 or the second control module 24 is used to obtain the distance between the seat 10 and the target object during the execution of the preset adjustment mode, and the target object is located in the movement of the seat 10 In the direction, it is also used to control the seat 10 to stop executing the preset adjustment mode when the distance is less than the preset distance.

In some embodiments, the controller is used to obtain the distance between the seat 10 and the target object in the process of executing the preset adjustment mode, and the target object is located in the moving direction of the seat 10, and is also used to obtain the distance between the seat 10 and the target object when the distance is less than the preset adjustment mode. When the distance is set, the control seat 10 stops executing the preset adjustment mode.

In this way, the user does not need to observe in real time with the eyes during the adjustment process of the seat 10, and it can also avoid the seat 10 squeezing the surrounding people or obstacles during the adjustment, so as to realize the anti-pinch function of the seat 10 and avoid the seat 10 from being on the other side. Targets cause damage and reduce the risk of occupants being crushed by seat 10 .

Specifically, in some embodiments, the sensor 12 may also include a distance measuring sensor, and the distance measuring sensor may be used to measure the distance between the seat 10 and the target in the moving direction of the seat 10 . The ranging sensor may include, but not limited to, an infrared ranging sensor or an ultrasonic ranging sensor.

It should be pointed out that the acquisition of the distance between the seat 10 and the target object may be acquired in real time, or at regular intervals so as to reduce energy consumption. Wherein, the preset distance can be set according to the distance measurement accuracy of the distance measurement sensor and the adjustment speed of the seat 10 , which is not limited here.

In one embodiment, the preset distance is 9cm, and the occupants make the seat 10 move backward at a speed of 2cm/s through the button on the seat 10, and a carton is placed behind the seat 10, and the seat 10 moves backward at the rear of the seat 10. During the moving process, the ranging sensor detects and acquires the distance between the seat 10 and the carton in real time, and when the distance between the seat 10 and the carton is 8.8 cm, the seat 10 is controlled to stop moving backward.

It should be noted that the above-mentioned examples and specific numerical values are for the convenience of describing the implementation of the present application, and should not be construed as limiting the protection scope of the present application.

In some embodiments, the seat 10 can also be provided with a radar, which can emit electromagnetic waves to irradiate the target and receive its echo, thereby obtaining the distance information of the seat 10 and the target in the direction of motion of the seat 10 . Wherein, the radar device may be a millimeter wave radar, a microwave radar, or a laser wave radar, etc., which is not limited here.

In some implementations, during the execution of the preset adjustment mode, the current value of the two-speed motor 13 of the seat 10 is acquired, and when the current of the two-speed motor 13 is greater than the preset current, the seat 10 is controlled to stop performing the preset adjustment mode. Set adjustment mode. In this way, the anti-pinch function of the seat 10 can also be realized without the need for the user to observe in real time with eyes.

It should be explained that when the seat 10 performs the preset adjustment mode, when the adjustment of the position and/or deployment angle of the seat 10 is not hindered by obstacles, the two-speed motor used to adjust the state of the seat 10 13 is a normal working state, and the current flowing through the two-speed motor 13 is a normal working current. When the adjustment of the position and/or deployment angle of the seat 10 is hindered by an obstacle, the two-speed motor 13 is blocked and the two-speed motor 13 is locked. The current of the motor 13 increases sharply for a period of time. Therefore, it is also possible to judge whether the process of executing the preset adjustment mode of the seat 10 is hindered by detecting whether the current of the two-speed motor 13 is greater than the preset current.

Referring to FIG. 8, in some embodiments, the method for adjusting the seat 10 includes:

S70: During the execution of the preset adjustment mode, when the seat 10 moves to the mechanical stop of the seat 10, control the seat 10 to stop executing the preset adjustment mode.

In some embodiments, the first control module 23 or the second control module 24 is used to control the seat 10 to stop when the seat 10 moves to the mechanical stop point of the seat 10 during the execution of the preset adjustment mode. Execute preset adjustment mode.

In some embodiments, the controller is configured to control the seat 10 to stop executing the preset adjustment mode when the seat 10 moves to the mechanical stop of the seat 10 during the execution of the preset adjustment mode.

In this way, damage to the seat 10 and other components in the vehicle 100 due to over-adjustment of the seat 10 during the adjustment process can be avoided.

Specifically, the mechanical dead point of the seat 10 may be the maximum travel point of the seat 10 . For example, when the distance between the passenger seat 10 and the central control screen is 3 cm, the position of the seat 10 is the mechanical stop of the seat 10, and when the distance between the passenger seat 10 and the central control screen is 20 cm, the position of the seat 10 is is the mechanical dead point of the seat 10, when the angle between the backrest 111 of the seat 10 and the seat cushion 112 is 30°, the position of the seat 10 is the mechanical dead point of the seat 10, when the backrest 111 of the seat 10 and the seat cushion 112 are 30° The position of the seat 10 when the angle between the seat cushions 112 is 170° is the mechanical dead point of the seat 10 .

In some implementations, the sensor 12 can be used to determine whether the seat 10 has reached the mechanical stop. For example, the distance sensor can be used to detect the distance between the seat 10 and the central control screen and the distance between the seat 10 and the central control floor. The distance between them, the angle sensor can also be used to measure the angle between the backrest 111 and the seat cushion 112.

In one embodiment, when the distance between the seat 10 and the central control screen is 2 cm, the position of the seat 10 is the mechanical dead point of the seat 10, and the seat 10 is controlled to move backward by 5 cm at the first speed V1, and then the seat 10 is controlled to Move forward 8 cm at the first speed V1, and then control the seat 10 to move forward 15 cm at the first speed V1. During the process of moving the seat 10 forward 15 cm at the first speed V1, the distance sensor 12 detects the distance between the seat 10 and the central control screen. When the distance between them is equal to 2 cm, stop the seat 10 from continuing to move forward at the first speed V1 so as to prevent the seat 10 from damaging the central control platform of the vehicle 100 .

Referring to FIG. 9, in some embodiments, when there is no load on the seat 10, the seat 10 is controlled to perform a preset adjustment mode at a second speed V2 (step S40), including:

S41: During the execution of the preset adjustment mode, when the current vehicle speed is equal to zero, control the deployment angle of the seat 10 to a maximum value.

In some embodiments, the second control module 24 is configured to control the deployment angle of the seat 10 to a maximum value when the current vehicle speed is equal to zero during the execution of the preset adjustment mode.

In some embodiments, the controller is used to control the deployment angle of the seat 10 to a maximum value when the current vehicle speed is equal to zero during the execution of the preset adjustment mode.

In this way, when the current vehicle speed is equal to zero, the unfolding angle of the seat 10 is controlled to expand to a maximum value so as to place more items on the seat 10 or facilitate passengers to lie down and have a rest on the seat 10 .

Specifically, when the vehicle 100 is in the driving state, the expansion angle of the seat 10 is controlled to expand to the maximum value, and the motion stroke of the seat 10 is relatively large. Due to the relatively fast second speed V2, the seat 10 will generate relatively large motion during the motion process. Loud sound will affect the driver's attention and affect driving safety. Therefore, in order to ensure driving safety, when the current vehicle speed is equal to zero, the expansion angle of the seat 10 is controlled to expand to a maximum value. In some embodiments, when the vehicle 100 is in the P or N gear and the handbrake or EPB is in the parking state, the deployment angle of the seat 10 can be controlled to expand to the maximum value, so that the seat 10 can be deployed into a bed mode .
