A control unit 18 for an active suspension system 14 of a vehicle 10 having one or wheels 22 is provided. The control unit 18 comprises: at least one input for receiving a signal comprising data related to the topography of terrain in a driving direction of the vehicle 10; at least one output for outputting a control signal for controlling one or more suspension system actuators (34, Figure 2a) associated with each respective wheel 22; and a processing module. The processing module is arranged to: analyse data to identify a surface feature, e.g. bump or pot-hole 12; determine a desired wheel displacement relative to the vehicle body for each wheel 22 when each wheel 22 negotiates the surface feature 12; determine a control signal for suspension system actuators in dependence on the desired wheel displacement. The control signal defines future adjustments to the suspension system actuator 34 that are scheduled to coincide with a time period for which the wheels negotiate the surface feature; and output the control signal.
