A surface roughness estimator for a vehicle configured to generate a first surface roughness index value indicative of terrain surface roughness and to output a signal in dependence at least in part on the first surface roughness index value, the estimator being configured to receive first acceleration information indicative of a first acceleration along a first axis, receive second acceleration information indicative of a second acceleration along a second axis, calculate a combined value in dependence on the first acceleration and second acceleration, and adjust the combined value in dependence on a speed of the vehicle to generate the first surface roughness index value.
