摘要： A control system (200) configured to control a damping force of an actuator (502) of an active suspension system (104) of a vehicle (1) in response to an external disturbance of a wheel (FL, FR, RL, RR) with which the actuator is associated, the control system comprising one or more controllers (301), wherein the control system is configured to: receive (902) a sensed displacement parameter (Z, A) indicative of suspension displacement associated with the wheel; determine (906) whether a condition (700) is satisfied, wherein satisfaction of the condition requires the sensed displacement parameter to indicate a transition from a suspension displacing phase (t1-t2) associated with the external disturbance to a suspension restoring phase (t2-t3) associated with the external disturbance, and wherein satisfaction of the condition depends on an amount of suspension displacement (Z) indicated by the sensed displacement parameter; and output (908) a signal to control the damping force to be greater, during the suspension restoring phase associated with the external disturbance, than if the condition is not satisfied, in dependence on satisfaction of the condition.
