Description

technical field

[0001] The invention relates to a vehicle active suspension hydraulic servo control system, which is suitable for the mechanical field. Background technique

[0002] Suspension system is one of the important devices of the car, which affects the ride comfort and stability of the vehicle. From the perspective of control, vehicle suspension can be divided into passive suspension, semi-active suspension and active suspension. Active suspension uses active controllable components to form a closed-loop control system, which can actively respond to road excitation conditions and vehicle motion to improve vehicle performance. At present, most of the vehicle active suspension systems use electro-hydraulic control, which can be roughly divided into high-response flow servo valves and proportional pressure valves.

[0003] In some domestic literatures about electro-hydraulic active suspension, the hydraulic actuator is abstracted as an active control force, without c...
