The report 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, along with the method employed for calculating ideal stopping distance. Results from tests and calculating ideal stopping distance. Results from tests and calculations are presented for two vehicles equipped with four-wheel antilock systems, which demonstrate that the method is viable and realistic. A means of comparing tire peak capability on a given surface to that produced by a standard tire is also discussed. (Author)
