Abstract

The invention relates to an automobile suspension control system based on an event trigger mechanism and a design method thereof. An automobile suspension includes four active suspensions. The control system includes an event trigger device, a state observer, a controller and a zero-order holder, which are connected in order. The output end of the automobile suspension is connected to the event trigger device. The zero-order holder and the input end of the automobile suspension are connected to form a control loop. The event trigger device includes triggers corresponding to the four active suspensions respectively. Each trigger triggers and works according to a set event trigger condition, and transmits output information of one corresponding active suspension to the state observer. The state observer transmits observed state information to the controller. The controller outputs corresponding control force according to the state information observed by the state observer, and then controls the corresponding active suspensions to work. Compared with the prior art, the automobile suspension control system has the advantages that the number of times of data transmission is reduced, resources are saved, the control cost is low, the system is highly practical and highly safe, etc.

Description

technical field [0001] The invention relates to a vehicle suspension control system and a design method thereof, in particular to a vehicle suspension control system based on an event trigger mechanism and a design method thereof. Background technique [0002] Suspension system plays an important role in vehicle performance control because it plays an important role in vehicle ride comfort, driver comfort and driving safety, and it is also a research hotspot in recent years. The suspension control system mainly includes three control modes: passive control, semi-active control and active control. Passive suspension is widely used because of its low price and high structural reliability, but its vibration reduction ability only depends on the characteristics of the system spring and damper. When the road surface disturbance is not within the design range, the control effect will not be ideal. On the basis of the passive suspension system, the semi-active suspension system re...
