A vehicle, a suspension controller and a method of controlling a suspension are provided. The vehicle 1 has a body 3 and a plurality of suspension units 9-1, 9-2, 9-3, 9-4 mounted to the body 3. The suspension units 9-1, 9-2, 9-3, 9-4 are associated with respective wheels 4-1, 4-2, 4-3, 4-4 of the vehicle 1 and one or more of said suspension units has at least one adjustable actuator 10-1, 10-2, 10-3, 10-4. The vehicle has sensing means for sensing a pitch angle (α) and/or a roll angle (β) of the body relative to an absolute horizontal plane (PXY). A controller 2 is provided having at least one processor 15 configured to receive a pitch angle signal and/or a roll angle signal from said sensing means. A memory device 16 is connected to the at least one processor 15. In dependence on said pitch signal and/or said roll signal, the at least one processor 15 is configured to output a control signal to control one or more of said adjustable actuators 10-1, 10-2, 10-3, 10-4 to reduce the magnitude of the pitch angle (α) and/or the magnitude of the roll angle (β) of the body 3. The present disclosure also relates to a controller for controlling at least one suspension unit to reduce the magnitude of a pitch angle (α) and/or a roll angle (β) of a body of a vehicle. The present disclosure further relates to a method of controlling at least one suspension unit.
