A control system (100 fig 1) is provided for an adaptive vehicle suspension system (270), the control system (100) comprising one or more controllers (110 fig 1). The control system (100) is configured to determine, that an impact with an object 230 has occurred at one or more wheels 212 of a first axle (210 fig 2A), preceding a second axle (220 fig 2A) in a direction of travel 240; determine if an impact with the object 230 at a wheel or wheels 222 of the second axle (220) is expected; and output a control signal to control via performance parameter the adaptive suspension system 270 at the second axle (220) if the impact at the wheel or wheels 222 of the second axle (220) is expected. Account may be taken of vertical suspension displacement and acceleration at the front exceeding thresholds and of a deduced vertical suspension velocity. Typically a valve actuator of a rear adaptive spring or an aperture actuator of a rear damper are controlled. The invention softens kerb strike loads at the rear of the vehicle.
