Abstract
The invention describes an apparatus and method for determining at least one wheel slip of a vehicle and at least one of a pitch angle, a road angle, a roll angle for use in at least one vehicle control system. The method and apparatus are characterized in that at least three deflection displacements are determined, and then at least one wheel slip of the vehicle and at least one of the pitch angle, the road angle, the roll angle of the vehicle are determined based on the at least three deflection displacements. The wheel slip(s) of the vehicle and at least one of the pitch angle, the road angle, and the roll angle of the vehicle may be provided or otherwise made available to the at least one vehicle control system.
