    • 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, V, A) indicative of suspension displacement associated with the wheel; determine (904, 906) whether at least one entry condition (600, 602, 700) is satisfied, in dependence on the sensed displacement parameter exceeding at least one entry condition threshold; and output (908) a signal to control the damping force to be greater, during a suspension restoring phase (t2-t3) associated with the external disturbance, than if the at least one entry condition is not satisfied, until an exit condition (910) is satisfied, in dependence on satisfaction of the at least one entry condition, wherein satisfaction of the exit condition (910) is dependent on the sensed displacement parameter indicating an end of the suspension restoring phase, comprising the sensed displacement parameter being below at least one exit condition threshold.
