Abstract
A control system (300) for controlling an active suspension system (104) of a vehicle (100), the active suspension system comprising suspension actuators (502), the control system comprising one or more controller (301), wherein the control system is configured to: in dependence on an activation signal (904), provide (908) a control signal to the active suspension system to cause the suspension actuators of the active suspension system to repetitively pulse vertical force through wheels (FR, FL, RR, RL) of the vehicle in a controlled pattern determined by the one or more controller, to vary wheel-to-surface contact patch forces, wherein the pattern comprises repetitively pulsing vertical force through at least one of the wheels at a first phase and through at least one other of the wheels at a second phase.
