Abstract

Air power brake system (APBS) on a vehicle was put forwarded in this paper to resolve that the braking distance couldn´t be effective curtailed because of the maximum ground braking force during vehicle braking. We analyzed its working principle, added Fa and researched on the basic simulation of control model. The academic feasibility of initiative air power brake system was expatiated, that was based on the principle of compressed air power reaction which was applied to the brake system, then established dynamics model of a new automotive brake system and simulation model of ABS&APBS based on MATLAB/Simulink. The simulated tests were designed to compare with the curve of vehicle speed and wheel velocity with APBS. The graph prove that APBS reduce braking distances at 6%-14% and braking time at 14%-32%. The results show that the new system can increase braking efficiency.
