Design and Analysis on the Anti-lock Braking Control System of A Four-wheel Vehicle

摘要

A PID Anti-lock Braking Control system has been designed according to the principle and method of vehicle dynamic. A vehicle dynamic mode which includes tire model, the controller model and braking model has been set up by the MATLAB/Simulink software. The vehicle straight line braking condition has been simulated by using the model, compared and analysed the influence of slip ratio and braking distance by the system, the results show that the design was effective and feasible which also can achieve the goal of prevent wheels locking.
