A control system (100 fig 1) comprising controllers (110 fig 1) is provided for a vehicle suspension system (290 fig 2a) comprising an active roll control system (180 fig 2a) and a variable stiffness spring system (190 fig 2a). The control system is configured to receive a total roll signal indicative of a total roll moment 310 of the vehicle. The total roll moment 310 is determined in dependence on a lateral acceleration 302 of the vehicle (600 fig 6). A received spring stiffness signal, indicative of a non-active roll moment component 314 of the vehicle (600), is dependent on a current spring stiffness mode of plural modes of the variable stiffness spring system. The control system (100) determines a target active roll moment component 318 of the vehicle, in dependence on the total roll moment 310 and the non-active roll moment component 314; and outputs an active roll control signal indicative of the target active roll moment component to the active roll control system to control the roll moment of the vehicle (600). The invention is aimed at controlling roll characteristics using coordination of relevant vehicle systems.
