1. A system for measuring the lateral inclination of a supporting surface upon which a vehicle is traversing, the vehicle having at least two laterally spaced means for contacting and traversing the supporting surface, the system including means carried on the vehicle for sensing the lateral inclination of the supporting surface and for generating an uncorrected lateral inclination signal, means for generating a signal indicative of the vehicle speed at at least one of the two laterally spaced contacting means, means for generating a signal indicative of the difference between the vehicle speeds at the two laterally spaced contacting means, and processor means, the processor means receiving the uncorrected inclination signal, the difference signal, and the speed signal and in response thereto, generating a corrected real lateral inclination signal, the real inclination signal being indicative of the true angle of lateral inclination of the supporting surface.
