PREDICTING THE BRAKING PERFORMANCE OF TRUCKS AND TRACTOR- TRAILERS. PHASE III TECHNICAL REPORT

This report documents three digital computer programs for predicting the braking performance of commercial highway vehicles. The computer programs were developed by the Highway Safety Research Institute of the University of Michigan under the sponsorship of the Motor Vehicle Manufacturers Association. The three programs are applicable to straight trucks, tractor-semitrailers, and doubles combination vehicles. The programs model these vehicle types in detail and include the effects of tandem suspension dynamics, air brake system dynamics, brake fade, antilock system performance, and sprung mass dynamics. The research studies leading to the development of the programs are discussed. The report concludes with a discussion of appropriate applications of these programs, and with a recommendation for further research into the areas of truck tire mechanics, the mechanical friction brake, and antilock systems.
