Abstract: This paper presents the simulation in MATLAB/SIMULINK of an anti-lock braking system (ABS) by means of a one quarter vehicle mathematical model, which simulate the braking dynamics of a car during a sudden braking, in addition a PID control is implemented to control the slip different road conditions. It also compares performance of the proposed controller with an uncontrolled sliding brake system and hysteresis type controller that shows the ability to significantly reduce braking distance and time in addition to controlling the slipping during a sudden braking.

Keywords: PID controller, hysteresis controller, anti-lock braking system, slip, friction coefficient, braking torque
