Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by persons skilled in the art based on the embodiments in the present application in light of the present disclosure, are within the scope of protection of the present application.
The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the above-described drawings (if any) are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It should be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the application described herein may be implemented in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
With the rapid development of science and technology, people put forward higher requirements on the comfort of vehicles, and the vehicles mainly reduce the vibration of the vehicle body through a shock absorber in the driving process, so that the comfort in the driving process is improved. The shock absorber has a plurality of working grades, and different working grades correspond to different damping forces.
In the setting of the vehicle, different driving modes correspond to different working levels of the shock absorber, the driving mode can be automatically switched according to the operation of a user on the vehicle during the running process of the vehicle, so that the working level of the shock absorber can be indirectly adjusted, at the moment, the condition required by the vehicle for switching the driving mode is the operation of the user, whether the driving mode is required to be switched by the user is judged according to the operation of the user, for example, when the speed of the user for stepping on the accelerator pedal is greater than a set threshold value, the situation that the user wants sufficient power at the moment is indicated, and the driving mode can be switched to the corresponding driving mode. In addition, the vehicle can automatically switch the driving mode according to the information such as the fuel quantity, the vehicle speed and the like of the vehicle, and further indirectly adjust the working grade of the shock absorber. In this case, the condition required for the vehicle to switch the driving mode is information such as the fuel amount of the vehicle, the vehicle speed, etc., and the vehicle determines the corresponding driving mode based on the information such as the fuel amount of the vehicle, the vehicle speed, etc., in order to balance the energy saving and the sufficient power of the vehicle.
When the vehicle runs on different roads, the vehicle automatically switches the driving mode according to the operation of a user, the fuel quantity and the vehicle speed, and then indirectly adjusts the working grade of the shock absorber, so that the matching degree of the working grade of the shock absorber and the road condition is low.
In order to improve the matching degree between the road surface condition and the working level of the shock absorber, the inventor considers that when a vehicle runs on different road surfaces, the current range of an electromagnetic valve in the shock absorber of the vehicle and the acceleration range of the vehicle in the vertical direction are different according to the difference of the vehicle speed, so that the working level of the shock absorber can be calibrated according to the vehicle speed and the current range of the electromagnetic valve, or the vehicle speed and the acceleration range of the vehicle in the vertical direction. When the vehicle runs, the acceleration of the vehicle in the vertical direction and/or the current of the electromagnetic valve exceed the range corresponding to the current level of the shock absorber, the working level of the shock absorber can be determined according to the speed of the vehicle and the acceleration of the vehicle in the vertical direction and/or the current of the electromagnetic valve, so that when the vehicle runs on different road surfaces, the working level of the shock absorber determined by the vehicle is different, and the matching degree of the road surface condition and the working level of the shock absorber is higher. Based on the inventive concept, the control scheme of the vehicle shock absorber in the application is designed.
For example, an application scenario of the control method for the vehicle shock absorber provided by the present application is described below, the present application may be applicable to a vehicle running under various road conditions, and in order to improve comfort of a user driving the vehicle or riding the vehicle, the vehicle is usually provided with the shock absorber to reduce jolt of the vehicle during running. Generally speaking, the shock absorbers correspond to different working levels according to different generated damping forces, in the application, a user wants that a vehicle can adaptively adjust the working levels of the shock absorbers according to road conditions, and can preset an adaptive mode of the shock absorbers, in the mode, the working levels of the shock absorbers can be adaptively adjusted according to the vehicle speed and by combining the acceleration of the vehicle in the vertical direction and/or the current of an electromagnetic valve, and in the application scene, the user can preset the adaptive mode of the shock absorbers.
For example, fig. 1 is a schematic diagram of a vehicle Control system provided in the present application, and as shown in fig. 1, the Control of the shock absorber may be performed by a Unit having a Control function in the vehicle, for example, the Control may be generally performed by an Electronic Control Unit (ECU) in the vehicle. The ECU can respond to the damper self-adaptive mode opened by a user to control the damper to work, the current operation parameters of the damper are detected, the current operation parameters of the damper can be various, the acceleration of the vehicle in the vertical direction, the current of the electromagnetic valve and the like, the current grade and the vehicle speed of the damper can be further obtained, the vehicle speed, the acceleration of the vehicle in the vertical direction and the current of the electromagnetic valve can be obtained in real time, and then the ECU determines the corresponding current range and/or acceleration range according to the current grade and the real-time obtained vehicle speed of the damper.
When the road condition changes, the acceleration of the vehicle in the vertical direction and the current of the electromagnetic valve, which are acquired in real time, can change, and when the acceleration of the vehicle in the vertical direction, which is acquired in real time, is not in an acceleration range or the current of the electromagnetic valve, which is acquired in real time, is not in a current range, the ECU can determine the target working grade of the shock absorber according to the current vehicle speed, which is acquired in real time, in combination with the acceleration of the vehicle in the vertical direction and/or the current of the electromagnetic valve, which is acquired in real time.
And then the ECU controls the damper to operate according to the target working grade of the damper, so that the working grade self-adaption actual road condition of the damper is realized, and the matching degree of the road condition and the working grade of the damper is improved.
It should be noted that the application scenario is only a schematic diagram of an application scenario provided in the embodiment of the present application, and the embodiment of the present application does not limit actual forms of various devices included in the application scenario, nor limits an interaction manner between the devices, and in a specific application of a scheme, the application scenario may be set according to actual requirements.
The technical solution of the present application will be described in detail below with reference to specific examples. It should be noted that the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
Fig. 2 is a schematic flowchart of a first embodiment of a control method for a vehicle shock absorber, where an execution main body of the embodiment of the present application may be an ECU and is implemented in a software manner. It is understood that the implementation may be realized by other hardware, or a combination of hardware and software. As shown in fig. 2, the control method of the vehicle shock absorber specifically includes the steps of:
s201: during the running of the vehicle, the current operating parameters of the shock absorber are detected.
During the running process of the vehicle, the working grade of the shock absorber can be adjusted in a self-adaptive mode according to the road surface condition.
In this step, during the running of the vehicle, the ECU detects the current operating parameters of the shock absorber, so as to determine the target working level of the shock absorber according to the current operating parameters of the shock absorber in the following, the working level of the shock absorber corresponds to the magnitude of the damping force generated by the shock absorber, and the damping forces corresponding to different working levels are different.
Illustratively, detecting the current operating parameter of the shock absorber includes: acceleration of the vehicle in the vertical direction, or current of a solenoid valve in the shock absorber. The ECU may acquire the acceleration of the vehicle in the vertical direction through the acceleration sensor.
It should be noted that the condition for triggering the vehicle adaptation to adjust the working level of the shock absorber according to the road surface condition may be: when the vehicle starts to run, the working grade of the shock absorber can be automatically adjusted according to the road condition. The conditions for triggering the vehicle adaptation to adjust the working level of the shock absorber according to the road surface condition may also be: a user starts a self-adaptive mode of the shock absorber, the starting of the mode indicates that the user does not need to manually switch the working level of the shock absorber, and the vehicle can self-adaptively adjust the working level of the shock absorber according to the road condition in the mode. The embodiment of the application does not limit the condition for triggering the self-adaption of the vehicle to adjust the working grade of the shock absorber according to the road condition, and can be set according to the actual condition.
It should be noted that, the way for the user to turn on the adaptive mode of the shock absorber may be by turning on a corresponding physical switch on the vehicle; the button on the graphical user interface on the vehicle-mounted terminal can be clicked; it is also possible to send an instruction to the vehicle to switch on the damper adaptation mode by means of the terminal device. The method and the device for starting the self-adaptive mode of the shock absorber are not limited, and can be selected according to actual conditions.
It should be noted that the shock absorber may be a hydraulic shock absorber, a magnetorheological shock absorber, or a semi-active suspension system, and the embodiment of the present application does not limit the type of the shock absorber, and may be selected according to actual situations.
S202: and judging whether the current operating parameters of the shock absorber are matched with the current working grade of the shock absorber, and if not, determining the target working grade of the shock absorber according to the current running speed and the current operating parameters of the vehicle.
In this step, after the ECU detects the current operating parameter of the shock absorber, it is necessary to determine whether the current operating parameter of the shock absorber matches the current working level of the shock absorber in order to determine whether the current road surface condition matches the current working level of the shock absorber. And if the current operation parameters are matched with the current working grade of the shock absorber, the current road condition is matched with the current working grade of the shock absorber, the working grade of the shock absorber does not need to be changed, and the shock absorber is controlled to operate according to the current working. If the current operation parameter is not matched with the current working grade of the shock absorber, it is indicated that the road condition changes at the moment, and the working grade of the shock absorber needs to be adjusted, so that the target working grade of the shock absorber needs to be determined according to the current running speed of the vehicle and the current operation parameter, and the working grade corresponds to the damping force generated by the shock absorber.
S203: and controlling the shock absorber to adjust from the current working grade to the target working grade for operation.
In the step, after the ECU determines the target working grade of the shock absorber, the ECU controls and controls the shock absorber to adjust from the current working grade to the target working grade to operate, and the working grade of the shock absorber is automatically adjusted according to the road surface condition.
After the ECU adjusts the operation level of the shock absorber, the ECU repeatedly executes steps S201 to S203 to automatically adjust the operation level of the shock absorber according to different road surface conditions.
According to the control method for the vehicle shock absorber, in the driving process of a vehicle, the ECU detects the current operation parameters of the shock absorber, when the current operation parameters are not matched with the working grade of the shock absorber, the target working grade of the shock absorber is determined, and then the working grade of the shock absorber is adjusted to the target working grade. Compared with the prior art, the working grade of the shock absorber is adjusted by switching the driving mode, when the road condition changes, the working grade of the shock absorber is determined through the current running parameters of the shock absorber and the vehicle speed, and the working grade is automatically adjusted, so that the matching degree of the road condition and the working grade of the shock absorber is effectively improved, and the user experience is improved.
Fig. 3 is a schematic flowchart of a second embodiment of the control method for the vehicle shock absorber provided by the present application, and as shown in fig. 3, on the basis of the above embodiment, the operating parameter may be the acceleration of the vehicle in the vertical direction, or the current of the solenoid valve in the shock absorber, and the target operating level of the shock absorber is determined and adjusted by referring to one of the operating parameters. Step S202 in the first embodiment can be implemented by the following steps:
s301: and determining the operation parameter range corresponding to the current running speed and the current working grade of the shock absorber according to the preset corresponding relation between the running speed of the vehicle, the working grade of the shock absorber and the operation parameter range of the shock absorber.
In this step, after the ECU detects the current operating parameter of the shock absorber, in order to determine when to adjust the operating level of the shock absorber, it is necessary to determine the operating parameter range corresponding to the current operating speed and the current operating level of the shock absorber according to the preset corresponding relationship between the operating speed of the vehicle, the operating level of the shock absorber, and the operating parameter range of the shock absorber.
Specifically, when the operation parameter is the current of the solenoid valve in the shock absorber, for example, table 1 shows the correspondence relationship between the running speed of the vehicle, the operation level of the shock absorber, and the current range of the solenoid valve.
TABLE 1
Figure BDA0003653056230000091
As shown in table 1, V represents the running speed of the vehicle, I represents the current of the battery valve, and the current range can be determined according to the current level of the shock absorber and the vehicle speed acquired in real time. For example, when the vehicle is running on a cement road, the current grade is a, the current vehicle speed is 30km/h, and according to table 1, the current range is I < 0.3A. When the vehicle runs on a cobblestone pavement, the obtained current grade is D, the current speed is 40km/h, and according to the table 1, the current range is 1.1A, I is more than or equal to 1.3A.
It should be noted that table 1 is only an example of a corresponding relationship between a driving speed of a vehicle, a working level of a shock absorber, and a current range of an electromagnetic valve, and the corresponding relationship is set in the vehicle by a worker before the scheme is executed, and the worker can determine the corresponding relationship through information such as a current value range collected under different road conditions. The working grade, the vehicle speed and the current range of the shock absorber and the corresponding relation of the working grade, the vehicle speed and the current range are not specifically limited, and the working grade, the vehicle speed and the current range can be set according to actual conditions.
In the case where the operation parameter is the acceleration of the vehicle in the vertical direction, for example, table 2 shows the corresponding relationship among the running speed of the vehicle, the operation level of the shock absorber, and the acceleration range.
TABLE 2
Figure BDA0003653056230000101
As shown in table 2, V represents the running speed of the vehicle, and the acceleration range can be determined based on the current level of the shock absorber and the vehicle speed acquired in real time. For example, when the vehicle is running on a concrete road, the current level is a and the current vehicle speed is 30km/h, and according to table 2, the acceleration range is [ -2, 2 ]. When the vehicle runs on the belgium road, the obtained current grade is E, the current vehicle speed is 40km/h, and according to table 2, the acceleration range is (— infinity, -10) U (10, + ∞).
It should be noted that table 2 is only an example of a corresponding relationship between the driving speed of the vehicle, the working level of the shock absorber, and the acceleration range, and the corresponding relationship is set in the vehicle by the worker before the implementation of the scheme, and the worker may determine the corresponding relationship by information such as the acceleration range collected under different road conditions. The working grade, the vehicle speed and the acceleration range of the shock absorber and the corresponding relation of the working grade, the vehicle speed and the acceleration range are not specifically limited, and the working grade, the vehicle speed and the acceleration range can be set according to actual conditions.
S302: judging whether the current operation parameter belongs to the determined operation parameter range; if the current operation parameter belongs to the determined operation parameter range, executing S303; if the current operating parameter does not belong to the determined operating parameter range, S304 is performed.
S303: and controlling the shock absorber to operate according to the current working grade.

When the vehicle runs to Belgium road, the ECU obtains that the current is 1.4A, the current speed is 20km/h, the road condition is changed due to the fact that 1.4A is not in the range that I is less than 0.3A, and the target working grade of the shock absorber is E according to the table 1.
It should be noted that the above example is only an example of the process of determining the target operation level of the shock absorber, and the embodiment of the present application does not specifically limit the road surface condition, the operation level of the shock absorber, the vehicle speed, the current magnitude, and the like, and can be determined according to the actual condition.
Optionally, after the ECU obtains the current of the electromagnetic valve in real time, the current of the electromagnetic valve may be filtered, and then the filtered current of the electromagnetic valve and the vehicle speed are used to determine the target working grade of the shock absorber.
Optionally, when the current of the electromagnetic valve is not within the current range, the ECU may continuously obtain the current of the electromagnetic valve for a preset time period, and then average the current for the preset time period, or average after filtering, and then determine the target working level of the shock absorber by using the average and the vehicle speed. The preset time length can be 3 seconds, 5 seconds or 10 seconds, and the preset time length is not limited in the embodiment of the application and can be set according to actual conditions.
In particular, when the operating parameter is the acceleration of the vehicle in the vertical direction, on the basis of the above example, the vehicle is exemplifiedWhen the vehicle runs on the cement road surface, the obtained current grade is A, the current vehicle speed is 50km/h, and according to the table 2, the acceleration range is [ -2, 2]. When the vehicle runs to a cobblestone pavement, the ECU acquires that the vertical acceleration of the current vehicle is 9m/s 2 The current vehicle speed is 50km/h, since 9m/s 2 Is not in [ -2, 2 [)]In the range (D), the target working class of the shock absorber is obtained from table 2, which shows that the road surface condition changes.
It should be noted that the above example is only an example of the process of determining the target operation level of the shock absorber, and the embodiment of the present application does not limit the road surface condition, the operation level of the shock absorber, the vehicle speed, the acceleration of the vehicle in the vertical direction, and the like, and can determine the operation level according to the actual condition.
Optionally, after acquiring the acceleration of the vehicle in the vertical direction in real time, the ECU may filter the acceleration, and then determine the target working level of the shock absorber by using the filtered acceleration and the filtered vehicle speed.
Optionally, when the acceleration of the vehicle in the vertical direction is not within the acceleration range, the ECU may continuously obtain the acceleration of the vehicle in the vertical direction for a preset time period, and further average the acceleration for the preset time period, or average the acceleration after filtering, and then determine the target working level of the shock absorber by using the average and the vehicle speed. The preset time length can be 3 seconds, 5 seconds or 10 seconds, and the preset time length is not limited in the embodiment of the application and can be set according to actual conditions.
According to the control method of the vehicle shock absorber, the working grade of the shock absorber is determined by combining the current of the electromagnetic valve or the acceleration of the vehicle in the vertical direction according to the vehicle speed, and the accuracy of the determined working grade of the shock absorber is effectively improved.
Fig. 4 is a schematic flow chart of a third embodiment of a method for controlling a vehicle shock absorber provided by the present application, and as shown in fig. 4, on the basis of the above embodiment, after an operating parameter within a set time period is obtained, the present embodiment performs a mean square error calculation on the operating parameter, and determines and adjusts a target operating level of the shock absorber according to a mean square error calculation result. Step S202 in the first embodiment can be implemented by the following steps:
s401: and calculating the mean square error according to the operation parameters in the current set time period.
In this step, after the ECU detects the current operating parameters of the shock absorber, in order to determine when to adjust the operating level of the shock absorber, it is necessary to perform a mean square error calculation according to the operating parameters within the current set time period.
Illustratively, the operating parameter is an acceleration of the vehicle in a vertical direction, and the preset time period is 3 seconds. The process of detecting the operating parameters of the shock absorber by the ECU is real-time, so that the operating parameters in a preset time period can be acquired. Therefore, after acquiring the acceleration of the vehicle in the vertical direction for 3 seconds, the mean square error calculation can be performed on these accelerations.
It should be noted that the operation parameter may also be the current of the solenoid valve in the shock absorber, and the preset time period may also be 1 second or 5 seconds. The embodiment of the application does not specifically limit the operation parameters and the preset time period, and can be selected and set according to actual conditions.
S402: judging whether the result of the mean square error calculation is matched with the current working grade of the shock absorber or not; if the result of the mean square error calculation is matched with the current working grade of the shock absorber, executing S403; if the result of the mean square error calculation does not match the current operation level of the shock absorber, S404 is performed.
S403: and controlling the shock absorber to operate according to the current working grade.
S404: it is determined that the current operating parameter does not match the current operating level of the shock absorber.
S405: and determining the target working level of the shock absorber according to the current running speed of the vehicle and the result of the mean square error calculation.
In the above steps, after the ECU performs the mean square error calculation, it is necessary to determine whether the result of the mean square error calculation matches the current working class of the shock absorber, and since there is a corresponding relationship between the vehicle speed, the mean square error range, and the working class of the shock absorber, it is possible to determine the corresponding mean square error range according to the current running speed of the vehicle and the current working class of the shock absorber, determine whether the result of the mean square error calculation is within the determined mean square error range, and if so, indicate that the current operating parameters of the shock absorber match the current working class of the shock absorber, and further indicate that the current road condition matches the current working class of the shock absorber, and the ECU controls the shock absorber to operate according to the current working class without adjusting the working class of the shock absorber.
If the target working level of the shock absorber is not within the mean square error range, namely the result of the mean square error calculation is not matched with the current working level of the shock absorber, the current operating parameters of the shock absorber are not matched with the current working level of the shock absorber, and further the road surface condition changes at the moment, the working level of the shock absorber needs to be adjusted, and therefore the target working level of the shock absorber needs to be determined according to the current running speed of the vehicle and the result of the mean square error calculation.
According to the control method of the vehicle shock absorber, after the operation parameters are obtained, the mean square error calculation is carried out on the operation parameters, the working grade of the shock absorber is determined according to the mean square error calculation result, and the accuracy of the determined working grade of the shock absorber is effectively improved.
Fig. 5 is a schematic flow chart of a fourth embodiment of the control method for the vehicle shock absorber provided by the present application, and on the basis of the above embodiment, the operating parameters may be the acceleration of the vehicle in the vertical direction and the current of the solenoid valve in the shock absorber, and one of the acceleration of the vehicle in the vertical direction and the current of the solenoid valve in the shock absorber is used as a first parameter, and the other is used as a second parameter, and the target operation level of the shock absorber is determined and adjusted by referring to the first parameter and the second parameter. Step S202 in the first embodiment can be implemented by the following steps:
s501: and determining the range of the first parameter corresponding to the current running speed and the current working grade of the shock absorber according to the preset corresponding relation between the running speed of the vehicle, the working grade of the shock absorber and the range of the first operating parameter of the shock absorber.
In this step, after the ECU detects the current operating parameter of the shock absorber, in order to determine when to adjust the operating level of the shock absorber, it is necessary to determine the range of the first parameter corresponding to the current operating speed and the current operating level of the shock absorber according to the preset corresponding relationship between the operating speed of the vehicle, the operating level of the shock absorber, and the range of the first operating parameter of the shock absorber.
Specifically, when the acceleration of the vehicle in the vertical direction is the first parameter, for example, the acceleration range may be obtained according to table 2. When the current of the solenoid valve is the first parameter, for example, the current range can be obtained according to table 1.
S502: judging whether the currently running first parameter belongs to the range of the first parameter; if the currently running first parameter belongs to the range of the first parameter, executing S503; if the currently running first parameter does not belong to the range of the first parameter, S504 is executed.
S503: and controlling the shock absorber to operate according to the current working grade.
S504: a first target operating level of the shock absorber is determined according to the current running speed of the vehicle and the first parameter of the current operation.
S505: and determining a second target working level of the shock absorber according to the current running speed of the vehicle and the second parameter of the current operation.
In the above steps, after the ECU determines the range of the first parameter, the ECU determines whether the currently operating first parameter belongs to the range of the first parameter, and if the currently operating first parameter belongs to the range of the first parameter, it indicates that the currently operating parameter matches with the current working grade of the shock absorber, and then indicates that the current road condition matches with the current working grade of the shock absorber, and the ECU controls the shock absorber to operate according to the current working grade without adjusting the working grade of the shock absorber.
If the first parameter of the current operation does not belong to the range of the first parameter, the situation of the current road surface is changed, the situation is not matched with the level of the shock absorber, and the working level of the shock absorber needs to be adjusted, determining a first target working level of the shock absorber according to the current running speed of the vehicle and the first parameter of the current operation; and determining a second target working level of the shock absorber according to the current running speed of the vehicle and the second parameter of the current operation. So as to determine the target working level of the shock absorber according to the first target working level and the second target working level.
It should be noted that, the step of determining the first target operation level of the shock absorber and the step of determining the second target operation level of the shock absorber may be executed in sequence, in which the step of determining the first target operation level of the shock absorber is executed first, and then the step of determining the second target operation level of the shock absorber is executed; the step of determining the first target working grade of the shock absorber can be executed after the step of determining the second target working grade of the shock absorber is executed; it is also possible that the step of determining a first target operation level of the shock absorber and the step of determining a second target operation level of the shock absorber are performed simultaneously. The execution sequence of the step of determining the first target working level of the shock absorber and the step of determining the second target working level of the shock absorber is not limited in the embodiment of the application, and can be selected according to the actual situation.
S506: judging whether the first target working level is the same as the second target working level; if the first target working grade is the same as the second target working grade, executing S507; if the first target working level is different from the second target working level, step S504 to step S506 are executed until the second target working level is the same as the first target working level.
S507: and taking the first target working grade or the second target working grade as the target working grade of the shock absorber.
In the above steps, after the ECU determines the first target operation level of the shock absorber and the second target operation level of the shock absorber, in order to verify whether the determined first target operation level of the shock absorber is accurate, it is necessary to determine whether the first target operation level of the shock absorber is the same as the second target operation level of the shock absorber, if the first target operation level of the shock absorber is the same as the second target operation level of the shock absorber, it is determined that the determined first target operation level of the shock absorber is accurate, and the first target operation level or the second target operation level is used as the target operation level of the shock absorber.
If the two are different, it is determined that the determined first target working level of the shock absorber is not accurate, and the steps S504 to S506 need to be executed until the second target working level is the same as the first target working level, that is, the first target working level is determined again according to the current driving speed and the current operating first parameter of the vehicle, the second target working level is determined according to the current driving speed and the current operating second parameter of the vehicle, and whether the newly determined first target working level is the same as the second target working level is determined again until the second target working level is the same as the first target working level.
According to the control method of the vehicle shock absorber, the first target working level and the second target working level of the shock absorber are determined according to the vehicle speed, the current of the electromagnetic valve and the acceleration of the vehicle in the vertical direction, and when the first target working level is the same as the second target working level, the first target working level or the second target working level is used as the target working level of the shock absorber, so that the accuracy of the determined working level of the shock absorber is effectively improved.
