General Motors Proving Ground Tire Cornering Test Vehicle 710092

This paper discusses the prototype General Motors Proving Ground Tire Cornering Traction Test Vehicle, a device now under development to measure cornering traction and cornering-braking traction on test road surfaces, as well as real world roads.A description is given of the system design and capabilities, including operating features, transducing elements, tracking stabilization, and data signal processing. The equipment will measure cornering traction capabilities as influenced by dynamic slip angle, camber angle, braking, speed, road surface, and road surface contaminants. Comparisons are made with data obtained from laboratory equipment and the PG Model II Friction Traction Trailer.
