Abstract

The modern vehicle uses the mechanism Anti-lock Braking System (ABS) to maintain vehicle safety by controlling the wheel slip in a stable zone during braking process conditions. The main aim of the controller of the ABS braking is to give a controlled torque required to obtain an optimal wheel slip rate. The slip rate is expressed as a function of automobile linear velocity and the angular speed of the wheels. The ABS mechanism and many control ways are applied. Applying the braking force to the braking system, the response is simulated mathematically in Simulink models. Applying control strategies such as (ON-OFF) Bang-Bang control, PD type and PID type, maintaining the required slip rate is evaluated. It is concluded that using the Bang-Bang, PD and PID controllers give good braking performance since the vehicle velocity as well as the wheel angular speed are controlled at the same time which prevents skidding during braking conditions. It is also found that stopping time and distance are reduced in the PID controller to 23.61 m at stopping time is 2.319 seconds compared to without control, Bang-Bang, PD control.
