Abstract
This paper describes a method for determining vehicle braking efficiency whereby actual stopping distances achieved by the vehicle are compared to ideal stopping distances theoretically achievable if the vehicle brake system were able to modulate the brakes such that the tires produced peak braking forces throughout the stop. Test procedures are described for both vehicle and tire tests, and the method employed for calculating ideal stopping distance is given. Results are presented which demonstrate that the method is viable and realistic. A means of comparing tire peak force capability on a given surface to that produced by a standard tire is also discussed.
