[0031] Figure 1 FIG. 1 is a flow chart of a vehicle control method provided in an embodiment of the present application. Figure 1 As shown, the vehicle control method may include:
[0032] Step 101: When a first wheel of a vehicle is excited by a road surface, the acceleration, height and unsprung speed of the first wheel are obtained;
[0033] In some possible implementations of the embodiments of the present application, road surface excitation refers to a dynamic force on the vehicle caused by a change in road surface profile or road surface height. The embodiments of the present application do not limit the method used to detect whether the wheel is subjected to road surface excitation, and any available method can be applied to the embodiments of the present application.
[0034] In some possible implementations of the present application, the acceleration of the wheel in the present application can be detected by a vehicle body acceleration sensor, and the height and unsprung speed of the wheel can be detected by a height sensor. The unsprung vertical speed is the speed of the unsprung mass (such as the wheel) in the vertical direction.
[0035] Step 102: determining excitation information corresponding to the road surface excitation received by the first wheel according to the acceleration, height and unsprung speed of the first wheel;
[0036] In some possible implementations of the embodiments of the present application, step 102 may include: calculating the product of a first absolute value of the acceleration of the first wheel, a second absolute value of the height of the first wheel, and a third absolute value of the unsprung motion speed of the first wheel, to obtain excitation information corresponding to the road surface excitation received by the first wheel.
[0037] For example, assuming that the left front wheel of the vehicle is excited by the road surface, the acceleration, height and unsprung motion speed of the left front wheel of the vehicle are obtained as BodyAcc_FL, CornerHeiPosn_FL and Damper V_FL respectively. |BodyAcc_FL| is calculated and multiplied by |CornerHeiPosn_FL|, and then multiplied by |Damper V_FL| to obtain the excitation information corresponding to the road surface excitation received by the left front wheel.
[0038] Step 103: determining, based on the excitation information, a first electrical parameter that needs to be applied to a shock absorber of a second wheel of the vehicle when the second wheel is excited by the road surface; wherein the second wheel is a wheel corresponding to the front and rear of the first wheel;
[0039] In some possible implementations of the embodiment of the present application, the electrical parameter in the embodiment of the present application includes current or voltage. The corresponding relationship of the wheels in the embodiment of the present application is: the left front wheel corresponds to the left rear wheel, and the right front wheel corresponds to the right rear wheel.
[0040] In some possible implementations of the embodiments of the present application, step 103 may include: when the excitation information is greater than or equal to a first threshold and less than or equal to a second threshold, determining, based on the correspondence between the electrical parameters, wheel height and unsprung movement speed, a second electrical parameter corresponding to the height and unsprung movement speed of the second wheel when the second wheel is excited by the road surface, wherein the first threshold is less than the second threshold; and determining the second electrical parameter as the first electrical parameter.
[0041] In some possible implementations of the embodiments of the present application, a correspondence between the electrical parameter, the wheel height, and the unsprung speed may be established in advance. Optionally, a calibrator may calibrate the electrical parameter corresponding to a certain wheel height and a certain unsprung speed, obtain the correspondence between the electrical parameter, the wheel height, and the unsprung speed, and calibrate the first threshold and the second threshold.
[0042] Exemplarily, assuming that the left front wheel of the vehicle is first excited by the road surface, it is determined that the excitation information of the left front wheel being excited by the road surface is greater than or equal to a first threshold and less than or equal to a second threshold. When the left rear wheel is excited by the road surface, the electrical parameters corresponding to the height and unsprung speed of the left rear wheel are determined based on the correspondence between the electrical parameters, wheel height and unsprung speed, and the determined electrical parameters are used as the electrical parameters that need to be applied to the shock absorbers corresponding to the left and right wheels.
[0043] In some possible implementations of the embodiments of the present application, the vehicle control method provided by the embodiments of the present application may also include: when the excitation information is less than a first threshold, determining the electrical parameter requested by the electrical parameter request when the second wheel is excited by the road surface as the first electrical parameter, wherein the electrical parameter request is used to request the electrical parameter to be applied to the shock absorber of the second wheel.
[0044] In some possible implementations of the embodiments of the present application, the electrical parameter request for applying electrical parameters to the shock absorber of the second wheel when the second wheel is stimulated by the road surface includes but is not limited to: a skyhook control request, a groundhook control request, a steering operation request, etc.
[0045] Exemplarily, assuming that the left front wheel of the vehicle is first excited by the road surface, it is determined that the excitation information of the left front wheel excited by the road surface is less than a first threshold value. When the left rear wheel is excited by the road surface, a skyhook control request is obtained. The electrical parameters requested by the skyhook control request are determined as the electrical parameters that need to be applied to the shock absorbers corresponding to the left and right wheels.
[0046] In some possible implementations of the embodiments of the present application, the vehicle control method provided by the embodiments of the present application may also include: when the excitation information is greater than a second threshold, determining the electrical parameter applied to the shock absorber of the first wheel when the first wheel is excited by the road surface as the first electrical parameter.
[0047] For example, assuming that the left front wheel of the vehicle is first excited by the road surface, when the left front wheel of the vehicle is excited by the road surface, the electrical parameter applied to the shock absorber of the left front wheel is I FL When the left rear wheel is stimulated by the road surface, I FL Determine the electrical parameters that need to be applied to the shock absorber of the left rear wheel.
[0048] Step 104: When the second wheel is excited by the road surface, the shock absorber of the second wheel is controlled to generate a damping force according to the first electrical parameter to suppress the vibration of the second wheel when the second wheel is excited by the road surface.
[0049] In some possible implementations of the embodiments of the present application, step 104 may include: applying a first electrical parameter to the shock absorber of the second wheel to change the damping force generated by the shock absorber of the second wheel, thereby suppressing the vibration of the second wheel when the second wheel is excited by the road surface.
[0050] In the embodiment of the present application, when the first wheel of the vehicle is excited by the road surface, the acceleration, height and unsprung speed of the first wheel are obtained; according to the acceleration, height and unsprung speed of the first wheel, the excitation information corresponding to the road surface excitation received by the first wheel is determined; according to the excitation information, the first electrical parameter to be applied to the shock absorber of the second wheel when the second wheel of the vehicle is excited by the road surface is determined; wherein the second wheel is a wheel corresponding to the front and rear of the first wheel; when the second wheel is excited by the road surface, the shock absorber of the second wheel is controlled to generate a damping force according to the first electrical parameter to suppress the vibration of the second wheel when the second wheel is excited by the road surface. In this way, after the first wheel of the vehicle is excited by the road surface, when the second wheel corresponding to the front and rear of the first wheel is excited by the road surface, the shock absorber of the second wheel is suppressed according to the road surface excitation received by the first wheel, the vibration of the second wheel when the second wheel is excited by the road surface can be suppressed, the vibration of the second wheel when the second wheel is excited by the road surface can be timely reduced, good vehicle body and unsprung control can be achieved, and the vehicle ride comfort during vehicle driving is improved.
[0051] In some possible implementations of the embodiments of the present application, when the excitation information is greater than or equal to the first threshold and less than or equal to the second threshold and when the second wheel is excited by the road surface, before the shock absorber of the second wheel is controlled according to the first electrical parameter to generate the damping force, the vehicle control method provided in the embodiments of the present application may also include: when the second wheel is not excited by the road surface, controlling the shock absorber of the second wheel to generate the damping force according to the third electrical parameter, wherein the third electrical parameter is the minimum electrical parameter that needs to be applied to the shock absorber of the second wheel.
[0052] Exemplarily, assuming that the left front wheel of the vehicle is first excited by the road surface, it is determined that the excitation information of the left front wheel being excited by the road surface is greater than or equal to the first threshold and less than or equal to the second threshold. When the left rear wheel is not excited by the road surface, the minimum electrical parameters are first applied to the shock absorbers corresponding to the left and right wheels to meet the upcoming road surface excitation. When the left rear wheel is excited by the road surface, the electrical parameters corresponding to the height and unsprung movement speed of the left rear wheel are determined according to the correspondence between the electrical parameters, wheel height and unsprung movement speed. The determined electrical parameters are used as the electrical parameters that need to be applied to the shock absorbers corresponding to the left and right wheels, and then the determined electrical parameters are applied to the shock absorbers of the left and right wheels to change the damping force generated by the shock absorbers of the left and right wheels, thereby suppressing the vibration of the left and right wheels when the left and right wheels are excited by the road surface.

[0054] It can be understood that when the vehicle is moving forward, the first wheel in the embodiment of the present application is the front wheel of the vehicle body; when the vehicle is moving backward (for example, when reversing), the first wheel in the embodiment of the present application is the rear wheel of the vehicle body.
[0055] In some possible implementations of the embodiments of the present application, when the excitation information corresponding to the road surface excitation received by the first wheel is less than a first threshold value, it indicates that the road surface excitation received by the first wheel is small; when the excitation information corresponding to the road surface excitation received by the first wheel is greater than a second threshold value, it indicates that the road surface excitation received by the first wheel is large; when the excitation information corresponding to the road surface excitation received by the first wheel is greater than or equal to the first threshold value and less than or equal to the second threshold value, it indicates that the road surface excitation received by the first wheel is medium or moderate.
[0056] In some possible implementations of the embodiments of the present application, when the first wheel is first subjected to road excitation and the road excitation received by the first wheel is relatively small, when the second wheel is subjected to the road excitation, the electrical parameters requested by the current electrical parameter request are applied to the shock absorber corresponding to the second wheel to change the damping force generated by the shock absorber; when the first wheel is first subjected to road excitation and the road excitation received by the first wheel is moderate, the minimum electrical parameters are first applied to the shock absorber corresponding to the second wheel to meet the road excitation, and when the second wheel is subjected to the road excitation, the electrical parameters corresponding to the height and the unsprung movement speed of the second wheel are determined according to the correspondence between the electrical parameters, the wheel height and the unsprung movement speed, and the determined electrical parameters are applied to the shock absorber corresponding to the second wheel to change the damping force generated by the shock absorber; when the first wheel is first subjected to road excitation and the road excitation received by the first wheel is relatively large, when the second wheel is subjected to the road excitation, the electrical parameters applied to the shock absorber corresponding to the first wheel when the first wheel is subjected to road excitation are applied to the shock absorber corresponding to the second wheel to change the damping force generated by the shock absorber.
