As an important component that integrates functionality, safety, comfort and aesthetics, the seat has attracted the attention of major manufacturers and consumers. Among them, the side support of the seat is particularly important for the feel and comfort of the vehicle while driving.

[0003] In related technologies, the side wing support of vehicle seats remains relatively fixed after adjustment. However, the applicability of the fixed side wing support strength is poor, making it difficult to meet the needs of drivers and passengers for side wing support under different driving conditions. For example, under the driving condition of fixed side wing support strength, if the vehicle turns quickly, the center of gravity of the driver and passengers will shift significantly. At this time, the side wing can no longer provide effective support, which will affect the comfort of the driver and passengers. Summary of the Invention

According to the switching frequency corresponding to the different cycles, the switching device is controlled to open or close to adjust the amount of air pumped to the side air bag, so as to adjust the pressure value of the side air bag to the desired pressure value of the corresponding cycle, until the pressure value of the side air bag reaches the target pressure value.

[0023] In related technologies, the support strength of the vehicle's side wing supports can be adjusted by inflating / deflating the side wing airbags with an air pump. However, when using a regular air pump, the inflation process is very slow. Although this ensures the comfort of the driver and passengers during inflation, it sacrifices the adjustment response speed of the side wing supports. On the other hand, when using a high-pressure air pump, the inflation speed is faster, causing the side wing airbags to pop out too quickly and with greater force, thus causing discomfort to the driver and passengers.

[0024] To address the problems existing in the aforementioned related technologies, this embodiment provides a method, device, electronic device, storage medium, and vehicle for adjusting vehicle seats.

[0025] like Figure 1 As shown in the figure, an embodiment of the present invention provides a method for adjusting a vehicle seat, wherein the seat is provided with side wing supports and a side wing adjustment device for adjusting the support strength of the side wing supports. The method for adjusting a vehicle seat includes the following steps: Step S100: Obtain vehicle speed information and turning information, wherein the turning information includes turning angle and / or lateral acceleration.

[0026] In some embodiments, vehicle speed information can be obtained by detecting a vehicle speed sensor configured on the vehicle, turning angle can be obtained by detecting a steering angle sensor configured on the vehicle, and lateral acceleration can be obtained by detecting a yaw rate sensor configured on the vehicle. Alternatively, vehicle speed and turning information can also be obtained using other methods.

[0027] Step S200: Determine the target support strength of the side wing support based on the vehicle speed and turning information.

[0028] Understandably, at a given vehicle speed, the greater the turning information, the greater the target support strength of the side wing support. Conversely, at a given turning information, the faster the vehicle speed, the greater the target support strength of the side wing support. In other words, the greater the turning information and / or the faster the vehicle speed, the stronger the feeling of body roll for the driver and passengers. Therefore, when turning too fast and / or with a greater turning information, the inertia is greater. Consequently, the target support strength of the side wing support should be adjusted to be greater to ensure that the side wing support has sufficient support strength to support the body of the driver and passengers, thereby improving the riding comfort of the driver and passengers.

[0029] Step S300: Based on the vehicle's turning information and the target support strength of the side wing support, determine the target time required for the side wing support to adjust from the initial support strength to the target support strength.

[0030] Specifically, the turning information and the target time required to adjust the support strength of the side wing supports are inversely proportional. The greater the turning information, the greater the inertia, requiring a shorter target time to adjust the support strength for a rapid response. Conversely, the smaller the turning information, the smaller the inertia, allowing for a longer target time to adjust the support strength and avoid abrupt changes. Furthermore, the target support strength and the target time required to adjust the side wing support strength are directly proportional; that is, the greater the target support strength, the longer the target time, and vice versa. A mapping relationship exists between the vehicle's turning information, target support strength, and target time, which is pre-calibrated based on data from vehicle dynamic testing.

[0031] Step S400: Within the target time, the control side wing adjustment device adjusts the side wing support from the initial support strength to the target support strength according to a predetermined curve over time; wherein, the predetermined curve is a mathematical function that has a continuous rate of change and a consistent direction of change under the boundary constraints from the initial support strength to the target support strength.

[0032] Specifically, firstly, the adjustment process of the lateral support strength must be completed within the target time to avoid excessively long adjustment time. In addition, the adjustment of the lateral support strength is not a step-like change, but a continuous and smooth change according to a predetermined curve based on the time variable, ensuring that the lateral support strength is not subject to shock oscillations during the adjustment process. Among them, the mathematical function corresponding to the predetermined curve must have three characteristics: (1) Smoothness: The first derivative (rate of change) of the predetermined curve is continuous and without abrupt changes, avoiding mechanical shock and physical discomfort caused by acceleration step changes; (2) Monotonicity: The predetermined curve increases or decreases monotonically within the adjustment time, ensuring that the direction of support strength change is consistent and without repeated fluctuations; (3) Boundary constraints: The predetermined curve strictly satisfies the boundary conditions between the initial strength and the target strength to achieve accurate tracking. Among them, the mathematical function corresponding to the predetermined curve can be a fifth-order polynomial, an S-curve, etc. In this way, when the vehicle enters a curve and needs to strengthen the lateral support, the system will gradually increase the lateral support strength according to the predetermined curve, avoiding discomfort to the driver and passengers caused by instantaneous increase in support strength.

[0033] In some embodiments, the seat may have two side wing supports, respectively located on the left and right sides of the seat. There may also be two side wing adjustment devices, each corresponding to one of the two side wing supports. If the vehicle is turning left, the support strength of the left side wing support is increased to the target support strength; if the vehicle is turning right, the support strength of the right side wing support is increased to the target support strength. Furthermore, the seat may have other numbers and locations of side wing supports, which will not be described in detail in this embodiment.

[0034] In this embodiment, vehicle speed and turning information are acquired to provide data support for subsequently determining the target support strength of the side wing support. Based on the vehicle speed and turning information, the target support strength of the side wing support is determined. This determines the required support strength of the side wing support under the current vehicle condition to ensure passenger comfort during cornering. Based on the vehicle's turning information and the target support strength of the side wing support, the target time required for the side wing support to adjust from its initial support strength to the target support strength is determined, enabling the determination of the optimal adjustment time for the side wing support and achieving efficient support adjustment. Within the target time, the side wing adjustment device is controlled to adjust the side wing support from its initial support strength to the target support strength according to a predetermined curve over time. This predetermined curve is a mathematical function with a continuous rate of change and a consistent direction of change, satisfying the boundary constraints from the initial support strength to the target support strength. This ensures a smooth and natural transition in support strength adjustment, avoiding jerks or sudden forces during the adjustment process and improving system comfort and stability.

[0035] Optionally, the predetermined curve includes: the curve corresponding to a fifth-degree polynomial.

[0036] Specifically, the expression for the fifth-degree polynomial is as follows: ; in, , , , , , The coefficients of the fifth-degree polynomial, t For time variables, The time variable is t The support strength of the lateral wing supports varies depending on the specific calculation method. t This can be adjusted for time. Furthermore, if the entire adjustment process is divided into multiple cycles, then... t This can be set to the number of cycles corresponding to the current adjustment time. For example, if the adjustment process is divided into 10 cycles, then... t When =1, it indicates the first cycle. t =10 indicates the 10th cycle.

[0037] In this optional embodiment, the control side wing adjustment device adjusts the side wing support from the initial support strength to the target support strength according to the curve corresponding to the fifth degree polynomial. Since the curve corresponding to the fifth degree polynomial has continuous first and second derivatives, it can ensure that there are no sudden changes or steps in the support strength change process, avoid mechanical shock or riding discomfort, and significantly improve the smoothness of the adjustment process.

[0038] Optionally, such as Figure 2 As shown, this embodiment of the invention also provides a method for determining the coefficients in a fifth-degree polynomial, including the following steps: Step S210: Obtain the initial support strength, initial adjustment speed, and initial adjustment acceleration corresponding to the start of support strength adjustment, and obtain the end adjustment speed and end adjustment acceleration corresponding to the target support strength.

[0039] Specifically, the initial support strength is the support strength of the wing support when the adjustment is triggered, which can be 0 or an initial value. The initial adjustment speed and initial adjustment acceleration are the adjustment speed and adjustment acceleration of the wing support when the adjustment is triggered, and the final adjustment speed and final adjustment acceleration are the adjustment speed and adjustment acceleration of the wing support when the target support strength is reached after adjustment. In order to ensure that the entire adjustment process is smooth and has a linear adjustment feel, the initial adjustment speed and initial adjustment acceleration are both 0, and the final adjustment speed and final adjustment acceleration are also 0.

[0040] Step S220: Obtain the target number of cycles required for the preset support strength adjustment process, and the initial number of cycles corresponding to the support strength adjustment process.

[0041] Specifically, the target time corresponding to the adjustment process of the side wing support strength can be divided into N cycles. Therefore, the initial number of cycles for the support strength adjustment process is 0, and the target number of cycles is N. The target number of cycles is a preset value, which is related to the service life of the side wing adjustment device. In each cycle, the side wing adjustment device needs to adjust the support strength once. The more target cycles the target time corresponding to the adjustment process is divided into, the higher the adjustment frequency of the side wing adjustment device, resulting in a decrease in the service life of the side wing adjustment device, and vice versa. Therefore, testers will predetermine a target number of cycles based on the vehicle's dynamic test data. In some embodiments, the target number of cycles can be 10. That is, when the target time required for the adjustment process is 1.8s, then 1.8s is divided into 10 cycles, with each cycle corresponding to a time of 0.18s.

[0042] Step S230: Determine the coefficients of the fifth-order polynomial based on the initial support strength, initial adjustment speed, and initial adjustment acceleration corresponding to the start of support strength adjustment, the end adjustment speed and end adjustment acceleration corresponding to the target support strength, and the initial and target number of cycles in the process of adjusting the support strength of the wing support.

[0043] Specifically, assuming the initial cycle number corresponding to the start of the adjustment process is 0, i.e., t=0, and the target cycle number is N, i.e., t=N, according to the above... The fifth-degree polynomial can be obtained as follows: Initial support strength ; Target support strength: = ; Initial adjustment speed: = ; End of speed adjustment: = ; Initial adjustment acceleration = ; End of acceleration adjustment: = ; If the initial support strength is The target support strength is Furthermore, as mentioned above, the initial adjustment speed, initial adjustment acceleration, final adjustment speed, and final adjustment acceleration are all 0. Substituting these parameters into the above expression yields the coefficients of the fifth-degree polynomial. , , , , , .

[0044] In this optional embodiment, the coefficients of a suitable fifth-degree polynomial can be determined based on the initial support strength, initial adjustment speed, and initial adjustment acceleration corresponding to the start of support strength adjustment, the end adjustment speed and end adjustment acceleration corresponding to the target support strength, and the initial number of cycles and the target number of cycles in the process of adjusting the support strength of the wing support.

[0045] Optionally, the wing support includes wing airbags, and the wing adjustment device includes an inflation adjustment device. The support strength of the wing support can be the pressure value of the wing airbag, the inflation amount of the wing airbag, and the lifting height of the wing airbag. Corresponding to different support strengths, the target support strength can be the target pressure value, the target inflation amount, and the target lifting height. The initial support strength can be the initial pressure value, the initial inflation amount, and the initial lifting height. It should be noted that the initial pressure value is usually the atmospheric pressure value of the current environment, and the initial inflation amount and initial lifting height are the inflation amount and lifting height corresponding to the wing airbag when it is not inflated, and can be taken as 0.

[0046] This embodiment uses the support strength as the pressure value as an example for explanation. Figure 3 As shown, within a target time period, the control flank adjustment device adjusts the flank support from the initial support strength to the target support strength according to a predetermined curve, including the following steps: Step S310: Determine the expected pressure value corresponding to the side airbags in each cycle during the adjustment process according to the fifth-order polynomial; wherein, the duration of the adjustment process is divided into several target cycles, and each cycle during the adjustment process is each cycle between the initial cycle number and the target cycle number of the adjustment process.

[0047] Specifically, the initial number of cycles is 0, and the target number of cycles is N. Since the support strength corresponding to the initial number of cycles is the initial support strength, which is a known value, for each cycle from 1 to N, the number of cycles is... t Substitute (1-N) into the fifth-degree polynomial with known coefficients as described above. In this process, the expected pressure value corresponding to each cycle from 1 to N can be obtained.

[0048] Step S320: Based on the expected pressure values ​​corresponding to the side air bags in different cycles during the adjustment process, control the inflation adjustment device to adjust the pressure value of the side air bags to the target pressure value. In each cycle, control the inflation adjustment device to adjust the pressure value of the side air bags to the corresponding expected pressure value.

[0049] Specifically, each cycle corresponds to a different expected pressure value, thus dividing the entire adjustment process into multiple parts. The more parts there are, the smoother the adjustment process becomes. Therefore, this segmented control can meet the needs of rapid response while ensuring the smoothness and stability of the adjustment process.

[0050] In this optional embodiment, segmented control is adopted, which can not only meet the rapid response requirements of the wing support, but also ensure the smoothness and stability of the support strength adjustment process.

[0051] Optionally, the inflation regulating device includes an air pump and a switch assembly, with the air pump and the switch assembly connected via an air circuit.

[0052] In some embodiments, in order to ensure the inflation response speed, the air pump in this embodiment is a high-pressure air pump. The output pressure of the high-pressure air pump can typically reach hundreds of kPa to several MPa, and it has the characteristics of fast response and large flow rate.

[0053] In some embodiments, the switching component can be a solenoid valve. When the solenoid valve is open, the air passage between the air pump and the side air bag is connected, and the air pump can inflate the side air bag. When the solenoid valve is closed, the air passage between the air pump and the side air bag is disconnected, and the air pump cannot inflate the side air bag. Therefore, the inflation amount of the air pump to the side air bag can be controlled by controlling the switching frequency of the solenoid valve, thereby adjusting the pressure value of the side air bag.

[0054] like Figure 4As shown, based on the desired pressure values ​​corresponding to different cycles during the adjustment process, the inflation adjustment device is controlled to adjust the pressure value of the side airbags to the target pressure value, including the following steps: Step S410: Determine the switching frequency of the switching components for different cycles based on the expected pressure values ​​corresponding to the side airbags during the adjustment process.

[0055] Specifically, based on the pressure values ​​corresponding to the side airbags in different cycles, the target output value of the air pump can be determined. Then, based on the output value of the air pump after one switch of the switching assembly, the target output value of the air pump is divided by the output value of the air pump during each switch to obtain the number of times the switching assembly switches per unit time, i.e., the switching frequency of the switching assembly. The output value of the air pump when the switching assembly switches once is related to the model of the switching assembly.

[0056] Step S420: According to the switching frequency corresponding to different cycles, control the switching device to open or close to adjust the amount of air pump to inflate the side air bags, so as to adjust the pressure value of the side air bags to the desired pressure value of the corresponding cycle, until the pressure value of the side air bags reaches the target pressure value.

[0057] In this optional embodiment, the switching frequency of the periodic control switch assembly can be adjusted to the target pressure value of the side airbags, and the adjustment process is more gentle.

[0058] Optionally, turning information includes turning angle and / or lateral acceleration.

[0059] like Figure 5 As shown, the target support strength of the side wing is determined based on the vehicle's speed and turning information, including the following steps: Step S510: Determine whether the vehicle's turning angle meets the first preset condition. If the first preset condition is met, trigger the adjustment of the side wing support strength. Determine the target support strength of the side wing support based on the vehicle speed information and turning angle. The vehicle speed information, turning angle, and target support strength have a corresponding first preset relationship.

[0060] Specifically, at a given vehicle speed, the larger the turning angle, the greater the target support strength of the side wing support. Conversely, at a given turning angle, the faster the vehicle speed, the greater the target support strength of the side wing support. In other words, the larger the turning angle and / or the faster the vehicle speed, the stronger the feeling of body roll for the occupants. Therefore, the first preset relationship is: when the turning speed is too fast and / or the turning angle is too large, the target support strength of the side wing support should be adjusted to be greater so that the side wing support has sufficient support strength to support the body of the occupants, thereby improving the riding comfort of the occupants.

[0061] Specifically, the first preset relationship is a pre-defined correspondence relationship.

[0062] Step S520: Determine whether the lateral acceleration of the vehicle meets the second preset condition. If the second preset condition is met, trigger the adjustment of the support strength of the side wing support, and determine the target support strength of the side wing support based on the vehicle speed information and lateral acceleration. The vehicle speed information, lateral acceleration and target support strength have a corresponding second preset relationship.

[0063] Specifically, under a certain vehicle speed, the greater the lateral acceleration, the greater the target support strength of the side wing support. Conversely, under a certain lateral acceleration, the faster the vehicle speed, the greater the target support strength of the side wing support. In other words, the greater the lateral acceleration and / or the faster the vehicle speed, the stronger the feeling of body roll for the driver and passengers. Therefore, the second preset relationship is: when the turning speed is too fast and / or the lateral acceleration is greater, the target support strength of the side wing support should be adjusted to be greater so that the side wing support has sufficient support strength to support the body of the driver and passengers, thereby improving the riding comfort of the driver and passengers.

[0064] Specifically, the second preset relationship is a pre-defined correspondence relationship.

[0065] In this optional embodiment, it is determined whether to trigger the adjustment of the support strength of the side wing support based on the vehicle's turning angle and / or lateral acceleration, and a suitable target support strength to be adjusted is determined, so that the timing and amount of adjustment of the support strength of the side wing support are more accurate.

[0066] like Figure 6 As shown, Figure 6 This diagram illustrates a comparison between adjusting the support strength of the wing supports using a high-pressure air pump in a conventional manner and using a fifth-order polynomial. In the diagram, A represents the conventional adjustment method, while B1-B3 represent the fifth-order polynomial adjustment method. B1 represents adjustment at level one, B2 at level two, and B3 at level three. The levels one, two, and three are related to the number of divisions in the adjustment process (target number of cycles). Level one corresponds to a higher target number of cycles, while levels two and three correspond to lower target number of cycles. As can be seen from the diagram, compared to the conventional method, adjusting the support strength of the wing supports using a fifth-order polynomial results in a smoother change in support strength and allows for multi-level adjustment, moving beyond a single adjustment mode.

[0067] like Figure 7 As shown, an embodiment of the present invention provides a vehicle seat adjustment device 700, wherein the seat is provided with side wing supports and a side wing adjustment device for adjusting the support strength of the side wing supports. The vehicle seat adjustment device 700 includes: The data acquisition module 710 is used to acquire vehicle speed and turning information; The target support strength determination module 720 is used to determine the target support strength of the side wing support based on the vehicle's speed and turning information. The adjustment time determination module 730 is used to determine the target time required for the side wing support to adjust from the initial support strength to the target support strength based on the vehicle's turning information and the target support strength of the side wing support. The adjustment module 740 is used to control the flank adjustment device to adjust the flank support from the initial support strength to the target support strength according to a predetermined curve over time within a target time.
