[0002] With the progress of technology, further reduction in cost, and the increasingly fierce competition among automobile manufacturers, intelligent suspensions are increasingly applied to vehicles. At the current stage, the control method of intelligent suspensions is basically as follows: road surface information, vertical acceleration of the vehicle, yaw angular velocity, suspension height and other information of the vehicle are obtained through various sensors, and are fed back to a suspension control module. After the control module receives the corresponding sensor information, it judges the information, and according to a fixed control program, it issues corresponding instructions to each actuator, thereby completing the control of the suspension according to the predetermined function. However, this control program is unified and fixed, and cannot be configured according to the driving habits of individuals. If the control program needs to be replaced, the vehicle has to be sent to an authorized institution or an institution with modification capabilities for offline upgrading and replacement, which requires a lot of cost and time, and the upgraded program may not be more suitable for the habits of the driver than the original program.
