Description

technical field [0001] The invention belongs to the technical field of automobile suspension systems, and in particular relates to a hydraulic-electric integrated self-powered active suspension actuator and a control method thereof. Background technique [0002] During the driving process of the vehicle, the relative displacement between the sprung mass and the unsprung mass of the vehicle will be caused due to the unevenness of the road surface, which will cause the vehicle to vibrate. The suspension system is a key component that determines the dynamic performance of the vehicle, and it determines the ride comfort and ride comfort of the vehicle. At present, vehicle suspension systems mainly include passive suspension, semi-active suspension and active suspension. Because the parameters of the traditional passive suspension such as stiffness and damping are fixed, the vibration damping effect of the car is greatly limited, and the suspension vibration damping performance ...
