[0029] In the related art, some methods for actively adjusting the wing support are provided. The first solution is based on vision, which controls the inflation and deflation of the wing support system after judging the road ahead information, vehicle speed and steering angle. The defect of this solution is that it is highly dependent on camera perception and image processing capabilities, the cost is high, and it does not recognize the scene of providing wing support during straight-line acceleration. The second solution uses vehicle speed and steering angle as conditions for judging the adjustment of wing support. The defect of this solution is that when only the steering angle signal is used, it cannot identify the vehicle conditions that need support during straight-line acceleration and provide wing support scenes.
[0030] To this end, the present application provides a vehicle seat control method that can achieve active control of wing supports.
[0031] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.
[0032] like Figure 4 The vehicle of the present application may include a seat, the seat being provided with at least one wing support, wherein the seat may be a driver's seat or a passenger's seat. In the following description, the driver, the passenger, etc. are collectively referred to as occupants. The wing support may provide support for the occupants to enhance the occupants' sense of wrapping and improve the comfort of the occupants when driving or riding the vehicle.
[0033] The seat in the present application may be provided with a wing support, for example, a wing support may be provided on the seat back, etc.; the seat in the present application may also be provided with multiple wing supports, for example, wing supports may be provided on both the left and right sides of the seat back, or wing supports may be provided on both the left and right sides of the seat cushion. The state of the wing support may be switchable, and the state of the wing support may be adjusted according to the actual working condition of the vehicle. For example, the wing support may have a supporting state and a releasing state, in which the wing support may provide lateral support to the occupant in the supporting state, and in the releasing state, the wing support may release the support to the occupant.
[0034] like Figure 1 and Figure 2 According to an embodiment of the present application, the vehicle seat control method may include:
[0035] Step 1: Get the vehicle's driving status information.
[0036] The driving state information may include one or more of the following information: vehicle acceleration, steering, steering angle, and vehicle speed. The vehicle acceleration may include linear acceleration (x-axis acceleration of the vehicle) and lateral acceleration (y-axis acceleration of the vehicle); the steering may be left steering or right steering; the steering angle may be the inclination angle of the vehicle driving direction relative to the current direction of the vehicle; and the vehicle speed may be the driving speed of the vehicle. The driving state information may come from information collected by sensors provided on the vehicle body, such as obtaining information such as vehicle acceleration, steering, and steering angle by detecting using an IMU (Inertial Measurement Unit); for another example, the linear acceleration and steering acceleration of the vehicle body may be obtained by detecting using a vehicle body sensor; for another example, the vehicle speed may be determined by detecting the wheel speed. The driving state information may also be determined by an external device, such as a position detection device. By determining the driving state information of the vehicle, the state of the vehicle may be determined, such as whether the vehicle is in a high-speed straight-line driving state, a straight-line accelerated driving state, a high-speed left-turn driving state, a left-turn accelerated driving state, a high-speed right-turn driving state, a right-turn accelerated driving state, and a low-speed driving state.
[0037] Step 2: Control the working state of the wing support according to the driving state information.
[0038] The working state of the side wing support can be determined according to different driving conditions, so that the vehicle can provide a comfortable riding environment for the passengers in different driving conditions, and effectively improve the comfort and safety of the seat. For example, when the vehicle is in different acceleration states or at different steering angles, the working state of the side wing support can be adjusted to improve the wrapping and support feeling of the passengers.
[0039] The working state includes at least a supporting state and a releasing state. That is, in the present application, the working state of the wing support is determined by the driving state information, wherein the seat may be provided with one wing support, and the working state of the wing support is determined according to the driving state information; or, the seat may be provided with two wing supports, and the working states of the two wing supports are determined according to the driving state information, or the working state of one of the two wing supports is determined, etc. In addition, the seat in the present application may also be provided with more than three wing supports, etc.
[0040] According to the seat control method of the embodiment of the present application, the working status of the wing support can be determined according to the driving status information of the vehicle, and the wing support can be quickly adjusted according to the driving status of the vehicle, so as to timely and actively control the wing support, so as to provide the occupants with good riding comfort and improve the stability and safety of the vehicle.
[0041] like Figure 2 The working state of the wing support in the present application can be determined according to the driving state information, and the driving state information can include information such as vehicle acceleration, vehicle speed, steering and steering angle. The method for determining the working state of the wing support in the present application can include but is not limited to the following implementation methods.
[0042] In implementation mode 1, the driving state information includes vehicle body acceleration, wherein the vehicle body acceleration may include the linear acceleration of the vehicle, and may also include the lateral acceleration of the vehicle. Wherein, controlling the working state of the wing support according to the driving state information includes:
[0043] If the vehicle body acceleration a0 is greater than or equal to the acceleration threshold a1, a0 ≥ a1, then the side wing support is controlled to be in the support state. The acceleration threshold can be set to be greater than 0 m / s 2 Preferably, the acceleration threshold is set to be greater than 3m / s 2 , further preferably, the acceleration threshold is set to be greater than 5 m / s 2 .
[0044] In some examples, if the steering angle of the vehicle is less than the first angle threshold, and the body acceleration is greater than or equal to the acceleration threshold, the vehicle is in a linear acceleration state, and the working state of the wing support is determined to be a support state. At this time, the wing support can provide support for the occupants, enhance the occupants' sense of wrapping, and improve the occupants' riding or driving comfort. The wing support can support the occupants' backs or left and right sides. The first angle threshold can be set to be greater than 0° and less than 15°, and the first angle threshold can be determined according to the type of vehicle, design purpose, etc. In addition, the first angle threshold can be set to a calibrated value or an adjustable value.
[0045] In some other examples, at least one wing support includes a first wing support provided on the left side of the seat and a second wing support provided on the right side of the seat, wherein the driving state information also includes a steering angle, and the controlling the working state of the wing support according to the driving state information also includes: if the steering angle of the vehicle is less than a first angle threshold, it can be determined that the vehicle is in a linear acceleration state, then the working state of the first wing support is controlled to be a supporting state, and the working state of the second wing support is controlled to be a supporting state. At this time, the first wing support and the second wing support can provide support for the occupant, enhance the occupant's sense of wrapping, and improve the occupant's riding or driving comfort.
[0046] For example, the wing support may include a first air bag arranged on the left side of the seat and a second air bag arranged on the right side, wherein the first air bag and the second air bag will be in a supporting state after the inflation amount reaches a predetermined value; and the first air bag and the second air bag will be in a released state after being deflated. The first air bag and the second air bag are connected by an air pump and a control valve to adjust the air storage amount in the air bag. According to the above example of the present application, when the occupant gets on the vehicle and fastens the seat belt, the vehicle speed reaches a vehicle speed threshold (for example, 40KM / h, which can be a calibrated fixed value or an adjustable value), and a linear acceleration signal value is detected that is an acceleration threshold (for example, 3m / s 2 , which can be a calibrated fixed value or an adjustable value), an inflation signal Qm is sent to trigger the control valve to simultaneously connect the first airbag, the second airbag and the air pump passage, and at the same time drive the air pump to work so that the connected first airbag and the second airbag are inflated. The occupant leans backward due to inertia, and the inflated airbag supports the rear of the occupant. After the inflation is completed, the preset length of time (for example, 3s, which can be a calibrated fixed value or an adjustable value) is maintained. If the acceleration is less than the acceleration threshold, a deflation signal is sent, the solenoid valve performs the deflation action, and the airbag is deflated, otherwise the original inflation state is maintained.
[0047] In some further examples, at least one side wing support includes a first side wing support provided on the left side of the seat and a second side wing support provided on the right side of the seat, wherein when the vehicle is turning left, the working state of the second side wing can be set to a supporting state (the working state of the first side wing support can be a supporting state or other states, such as a released state); and / or, when the vehicle is turning right, the working state of the first side wing can be set to a supporting state (the working state of the second side wing support can be a supporting state or other states, such as a released state).
[0048] In implementation mode 2, the driving state information further includes a steering angle, wherein the steering angle may be a steering angle when the vehicle turns left or a steering angle when the vehicle turns right. Wherein, controlling the working state of the wing support according to the driving state information further includes: if the steering angle B0 of the vehicle is greater than or equal to a second angle threshold B2, that is, B0 ≥ B2, then controlling the working state of at least one wing support to be a support state. When the vehicle turns, the wing support may be used to offset the centrifugal force of the occupant during the turning process, provide lateral support for the occupant, and thus improve the riding or driving comfort.
[0049] In addition, in some embodiments, at least one wing support includes a first wing support provided on the left side of the seat and a second wing support provided on the right side of the seat, wherein the driving state information also includes steering information, and controlling the working state of the wing support according to the driving state information also includes:
[0050] If the vehicle's steering information indicates that the vehicle is turning right, the first wing support is controlled to be in a supporting state; if the vehicle's steering information indicates that the vehicle is turning left, the second wing support is controlled to be in a supporting state. This can provide the occupants with a support force opposite to the steering force, thereby providing the occupants with a centripetal force and improving comfort.
[0051] In some examples, the controlling the working state of the wing support according to the driving state information further includes: if the steering angle of the vehicle is greater than a second angle threshold, and the vehicle is in a steering state (the vehicle speed may be in an increasing, decreasing, or maintaining state), then controlling the working state of the first wing support and / or the second wing support to be a supporting state. When the vehicle is turning left, the working state of the second wing support may be set to a supporting state (the working state of the first wing support may be a supporting state or a released state, etc.); when the vehicle is turning right, the working state of the first wing support may be set to a supporting state (the working state of the second wing support may be a supporting state or a released state, etc.).
[0052] For example, the wing support may include a first air bag disposed on the left side of the seat and a second air bag disposed on the right side, wherein the first air bag and the second air bag are in a supporting state when the inflation volume reaches a predetermined value; and are in a releasing state when the first air bag and the second air bag are deflated. The first air bag and the second air bag are connected by an air pump and a control valve to adjust the air storage volume in the air bag. According to the above example of the present application, when the occupant gets on the vehicle and fastens his seat belt, and the vehicle speed reaches the vehicle speed threshold (for example, 40KM / h, which can be a calibrated fixed value or an adjustable value), it detects that the left turn angle signal value is greater than or equal to the second angle threshold B2 (for example, 10°, which can be a calibrated fixed value or an adjustable value), then the trigger module sends an inflation signal Qn, triggers the control valve to connect the second air bag and the air pump passage, and drives the air pump to work at the same time to inflate the connected second air bag. The occupant leans to the right due to inertia, and the inflated air bag supports the right side of the occupant. After the inflation is completed, it maintains a preset time (for example, 3s, which can be a calibrated fixed value or an adjustable value). If the steering angle returns to the correct position, a deflation signal is sent, the control valve performs the deflation action, and the air bag deflates, otherwise it maintains the original inflated state. On the contrary, turning right triggers the inflation of the first airbag. When the vehicle speed reaches the vehicle speed threshold (for example, 40KM / h, which can be a calibrated fixed value or an adjustable value), it detects that the right turn angle signal value is greater than or equal to the second angle threshold B2 (for example, 10°, which can be a calibrated fixed value or an adjustable value), then the trigger module sends an inflation signal Qn, triggers the control valve to connect the first airbag and the air pump passage, and drives the air pump to work so that the connected first airbag is inflated. The occupant leans to the left due to inertia, and the inflated airbag supports the left side of the occupant. After the inflation is completed, it is maintained for a preset time (for example, 3s, which can be a calibrated fixed value or an adjustable value). If the steering angle returns to the right position, a deflation signal is sent, and the control valve performs the deflation action to deflate the airbag.
[0053] In some embodiments, the working state further includes a pre-support state, and the controlling the working state of the wing support according to the driving state information further includes: if the steering angle is less than the second angle threshold and greater than the first angle threshold, the vehicle is in a steering state, but the steering angle is small, and the wing support does not need to be in a supporting state, then the working state of at least one wing support is controlled to be a pre-support state, wherein the first angle threshold is less than the second angle threshold. By setting the pre-support state, the wing support is between the supporting state and the released state, and when the wing support needs to be adjusted to the supporting state, the time required for the wing support to change from the pre-support state to the supporting state is less than the time required for the wing support to change from the released state to the supporting state, thereby shortening the time for the wing support to change from the released state to the supporting state, and realizing a rapid response of the wing support.
[0054] The pre-support state of the wing support is a state between the release state and the support state. For example, the wing support includes an air bag, and the first inflation amount of the air bag when the working state of the wing support is the pre-support state is less than the second inflation amount of the air bag when the working state is the support state. In this way, before the wing support is about to enter the support state, part of the gas is introduced into the air bag in advance, and when it is necessary to continue to inflate, the time taken to inflate the air bag to the support state is shortened.
[0055] For example, according to the above example of the present application, when the occupants get on the vehicle and fasten their seat belts, the vehicle speed reaches a vehicle speed threshold (for example, 40KM / h, which can be a calibrated fixed value or an adjustable value), and a left turn angle signal value is detected that is greater than a first angle threshold and less than a second angle threshold (for example, between 5° and 10°, which can be a calibrated fixed value or an adjustable value), the trigger module sends a pre-inflation signal, triggers the control valve to connect the second airbag and the air pump passage, and drives the air pump to work so that the connected second airbag is inflated. At this time, the inflation amount of the second airbag is less than the inflation amount in the supporting state. When the steering angle continues to increase to be greater than or equal to the second angle threshold When the steering angle reaches a value greater than the first angle threshold (for example, greater than 10°), the second airbag continues to be inflated, and the second airbag is in a supported state; when it is detected that the right turn angle signal value is greater than the first angle threshold and less than the second angle threshold (for example, between 5° and 10°, which can be a calibrated fixed value or an adjustable value), the trigger module sends a pre-inflation signal, triggers the control valve to connect the first airbag and the air pump passage, and drives the air pump to work so that the connected first airbag is inflated. At this time, the inflation amount of the first airbag is less than the inflation amount in the supported state. When the steering angle continues to increase to be greater than or equal to the second angle threshold (for example, greater than 10°), the first airbag continues to be inflated, and the first airbag is in a supported state.
[0056] In implementation mode 3, the driving state information further includes vehicle speed, and controlling the working state of the wing support according to the driving state information further includes: if the vehicle speed is greater than or equal to a vehicle speed threshold, controlling the working state of the wing support according to the driving state information; and / or, if the vehicle speed is less than the vehicle speed threshold, controlling the working state of the wing support to the release state. Whether the wing support needs to be adjusted to the support state can be determined according to the vehicle speed. When the vehicle speed is low, the wing support can be used to provide support for the occupant without the wing support; when the vehicle speed is high, the wing support can be used to quickly provide support for the occupant.
[0057] In implementation mode 4, the driving status information further includes a seat occupancy signal, and controlling the working status of the side wing support according to the driving status information further includes: if the seat occupancy signal of the vehicle indicates that an occupant is seated, controlling the working status of the side wing support according to the driving status information; and / or, if the seat occupancy signal of the vehicle indicates that no occupant is seated, controlling the working status of the side wing support to the released status.
[0058] For example, Figure 3 This is the workflow diagram for the wing support follow-up adjustment.
[0059] Step S1, the information processing module receives the vehicle speed signal, steering information, acceleration signal and seat occupancy signal sent by the vehicle body;
[0060] Step S2, determining whether the seat occupancy signal is valid, if it is valid, it means that the seat has been occupied by an occupant and proceeding to S3, otherwise the side wing support on the seat will not be activated;
[0061] Step S3, judging whether the vehicle speed s0 is greater than the vehicle speed threshold s1, the vehicle speed threshold s1 is specifically determined by actual calibration or negotiation, if it is greater than the vehicle speed threshold s1, proceeding to step S4, otherwise ending, the side wing adjustment system of the seat will not be started, wherein the vehicle speed threshold s1 can be set within the range of 0 KM / h to 60 KM / h, preferably, the vehicle speed threshold s1 can be set within the range of 20 KM / h to 50 KM / h, further, the vehicle speed threshold s1 can be set to 40 KM / h, and the vehicle speed threshold s1 can be a calibrated fixed value or an adjustable value;
[0062] Step S4, comprehensively judge the steering angle B0 and the acceleration a0, and meet the "or" condition for entering step S5, that is, the steering angle B0 is within the set range or the acceleration a0 is within the set range, which can trigger entering step S5. If both are not satisfied at the same time, the process ends, and the wing adjustment system on the seat will not start. Step S4 takes the judgment of decomposing and grading the received vehicle body signal into multiple groups, executes different inflation strategies and outputs them to step S5, triggering different inflation signals Q, which can effectively respond to the wing adjustment actuator in a timely manner. When responding to the inflation caused by the steering angle, specifically, when a left turn is received, the right airbag is inflated, and when a right turn is received, the left airbag is inflated. The left and right turn status and angle information of the vehicle are reflected in the steering angle information that the module needs to receive; when responding to the inflation triggered by the linear acceleration, specifically, when a linear acceleration signal is received, the left and right airbags are inflated at the same time, and the steering angle signal is responded to first; such as Figure 3 In step S4, when the steering angle B0 is very small but enters the interval determined by the module (for example, greater than the first angle threshold and less than the second angle threshold), it indicates that the vehicle is about to enter a curve state, and an inflation signal Qm2 is generated;
[0063] Step S5, the execution module performs inflation, which is equivalent to pre-inflation of the airbag;
[0064] Step S6, if the steering angle B0 continues to increase within the interval (for example, greater than the second angle threshold), an inflation signal Qm3 is generated, and the execution module inflates the airbag. At this time, the airbag state is superimposed on the previous state, and the time to inflate to the current state is shorter than that of a one-time filling, which is equivalent to a shortened response time. The above steering angles B1~Bn and acceleration values a1~an and the generated Q1~Qn need to be rigorously calibrated. Step S6 is the system waiting time M, which also needs actual calibration;
[0065] Step S7, the system receives a vehicle body signal again after S6. If the steering angle is less than the third angle threshold D and the acceleration is less than the second acceleration threshold E, the deflation signal is triggered, and then the next working cycle ends. The S7 condition is an "and" condition, otherwise the state is maintained until the next signal change.
[0066] In some embodiments of the present application, the driving state information also includes an active control signal, and the controlling the working state of the wing support according to the driving state information also includes: if the active control signal is obtained, the working state of the wing support is controlled according to the active control signal. In other words, the adjustment can be made according to user active control, mobile terminal control or cloud platform control, and the adjustment method of the car cover support can be expanded to meet the needs of more working conditions. For example, on a bumpy road, when the acceleration, speed, steering angle, etc. of the vehicle are relatively small, a comfortable riding experience can also be obtained through the main control.
[0067] In some embodiments, the wing support includes an air bag, and the control method further includes: when the working state is a supporting state, the air bag is in an inflated state; when the working state is a releasing state, the air bag is in a deflated state.
[0068] For example, the wing support may include a first air bag disposed on the left side of the seat and a second air bag disposed on the right side, wherein the first air bag and the second air bag are in a supporting state when the inflation volume reaches a predetermined value; and are in a releasing state when the first air bag and the second air bag are deflated. The first air bag and the second air bag are connected by an air pump and a control valve to adjust the air storage volume in the air bag.
[0069] The present application provides a comprehensive information judgment method based on vehicle speed, steering, vehicle acceleration, and seat occupancy status, which cooperates with the side wing adjustment device arranged on the seat to realize the real-time adjustment function of the vehicle seat side wing support, covering the steering scenarios and straight-line acceleration scenarios where the occupants need seat support, so that the occupants always have a sense of wrapping and comfort.
[0070] This application integrates the judgment of vehicle acceleration information, covers straight-line acceleration and also needs to provide supporting scenarios (application condition expansion); multi-level grouping is used for signal judgment, and pre-inflation is entered in advance, with a short response time.
[0071] Specifically, 1. It integrates the vehicle acceleration information judgment, covers the linear acceleration and also needs to provide support scenarios, which has a wider coverage than the existing solutions, such as Figure 3 In process S4, when the steering angle B0 is very small, the vehicle is not in a turning state, and the acceleration a0 is judged to be large, indicating that the vehicle is in a linear acceleration state, thereby triggering the inflation signal Qm1, and the execution module inflates the airbag to provide the seat wrapping and support feeling in the linear acceleration scene; 2. Compared with the traditional solution, there is a large response time difference between the side wing adjustment action and the body state, and the support cannot be provided in a timely manner. The received body signal is decomposed and graded into multiple groups, and different inflation strategies are executed, which can effectively respond to the side wing adjustment execution device in a timely manner. In addition, when the steering angle B0 is very small but enters the interval judged by the module, it means that the vehicle is about to enter the curve state, and the process S5 is entered. At this time, the inflation signal Qm2 is generated, and the execution module inflates, which is equivalent to pre-inflating the airbag, and the process S6 is entered. If the steering angle B continues to increase in the interval, the inflation signal Qm3 is generated, and the execution module inflates the airbag. At this time, the airbag state is superimposed on the previous state, and the time to inflate to the current state is shorter than that of a one-time filling, which is equivalent to shortening the response time.
[0072] Furthermore, when the car is driving on rough roads, the occupants can set the inflation level of the seat side wings through the active control switch to adjust the seat's support and wrapping feeling for the occupants.
[0073] The present application provides a system and control method for adjusting the seat wing support follow-up, such as Figure 4 The system is mainly composed of information processing module and execution module.
[0074] The signal processing module is used to obtain the vehicle's driving status information, where the driving status information includes vehicle speed signal, steering angle signal, acceleration signal, and seat occupancy signal. The above signals can be sent via Ethernet, CAN or LIN signals. Figure 2 The workflow processing can comprehensively judge the driving status of the vehicle and output corresponding signals to the execution module such as Figure 2 .
[0075] The air pump and solenoid valve response signals of the execution module are pulse width modulation signals (PWM), which drive the execution module to work. The execution module consists of an air pump, a solenoid valve connecting the air pump and the air bag, and an air bag arranged on the side wings of the seat back. The air bags can be multiple and can also be arranged on both sides of the seat cushion at the same time, such as Figure 5The figure is a schematic diagram of the layout of an airbag execution module.
[0076] According to an embodiment of the present application, the electronic device includes a processor, the processor is connected to a memory, the memory stores a computer program, and the processor executes the computer program to implement the aforementioned method.

The signal processing module 11 is used to obtain the driving state information of the vehicle, wherein the driving state information may include one or more of the vehicle body acceleration, steering, steering angle and vehicle speed. For example, the signal processing module 11 can be connected to an IMU (Inertial Measurement Unit) to obtain the vehicle body acceleration, steering and steering angle information; for another example, the signal processing module 11 can be connected to a vehicle body sensor to obtain the linear acceleration and steering acceleration of the vehicle body; for another example, the driving state information can also be determined by an external device (such as a position detection device, a mobile terminal or a cloud server, etc.), and the signal processing module 11 can be connected to an external device to obtain the driving state information of the vehicle. The control module 12 is connected to the signal processing module 11 and is configured to execute the steps of the aforementioned vehicle seat control method. The control module 12 can determine the working state of the wing support according to different driving states, so that the vehicle can provide a comfortable riding environment for the occupants in different driving states, and effectively improve the comfort and safety of the seat. For example, when the vehicle is in different acceleration states or at different steering angles, the working state of the wing support is adjusted to improve the wrapping feeling and support of the occupants. The execution module 13 is connected to the control module 12 and is controlled by the control module 12 to adjust the wing support. For example, the wing support includes an air bag, and the execution module 13 can be an air pump and a control valve for controlling the inflation and deflation of the air bag; for another example, the wing support is a baffle, and the execution module 13 can be a motor for controlling the rotation of the baffle. Through the aforementioned seat control device, the wing support can be quickly adjusted according to the driving status information of the vehicle, so as to timely and actively control the wing support, so as to provide good riding comfort for the occupants and improve the stability and safety of the vehicle.
