【Abstract】An Automotive braking system design and performance evaluation software is developed based on MATLAB/GUI. The software consists of four modules: proportioning valve (proportioning valve, pressure difference proportioning valve, load sensing proportioning valve, acceleration proportioning valve) used in computation and analysis of automobile braking system match; computation and analysis of braking system match for vehicle without proportioning valve; automotive braking stability computation, analysis and evaluation based on pedal force; ECE braking regulation requirement and curve. Simulation computation is carried out with a light duty truck as an example and compare the result with Carsim simulation, reliability and practicability of the software are thus validated.
