A control system (200, Fig. 2) and a method 600 for controlling an active suspension system (104, Fig. 2) of a vehicle (1, Fig.1 ) are provided. The active suspension system comprises a hydraulic circuit (17, Fig. 5). The hydraulic circuit comprises a hydraulic pump (P) and an accumulator (A1, A3). The control system comprises one or more controllers (201, Fig. 2). The control system is configured to obtain 602 a variable setpoint (p_ref) indicative of required hydraulic pressure in the hydraulic circuit of the active suspension system. The control system is configured to determine 604 a flow control parameter (Q_pump_dyn) for controlling hydraulic pressure to track the variable setpoint. The control system is configured to output 606 the flow control parameter to control the hydraulic pump of the active suspension system. The flow control parameter is proportional to a rate of change of the variable setpoint and inversely proportional to an instant value of the variable setpoint. An active suspension system (104, Fig. 4) including such a control system, a vehicle and computer software (208, Fig. 2) are also disclosed.
