1. A control system for controlling an active suspension of a vehicle, the control system comprising one or more controllers, the control system configured to:
detect or predict a transient suspension disturbance to the vehicle;
determine whether the transient suspension disturbance to the vehicle is from within a cabin of the vehicle; and
control a variable force parameter of the active suspension at one or more axles in dependence on (i) whether the transient suspension disturbance is from within the cabin of the vehicle and (ii) a detected roll angle or pitch angle, the variable force parameter controlling an extent to which the active suspension prevents cabin/body movement of the vehicle.
