Simulation Performance of Antilock Braking System under Different Drag Coefficients

Simulation performance of antilock braking system under different drag coefficient has been presented. The research is aimed at finding the effect of air drag force on the performance of a controller for an ABS during hard braking. Simulink model of a single tyre is obtained. A proportional integral and derivative (PID) controller is developed and integrated with the single tyre model. Simulation was performed in Matlab/Simulink. The results obtained shows that as the drag coefficient increases the braking or stopping distance decreases. This shows that the controller performed effectively irrespective of the increase in the air drag force around a braking vehicle under severe road condition.
