Abstract

Anti-lock braking system detects drastic changes in the speed of wheels. When a sharp deceleration is detected the anti-lock braking system will reduce the hydraulic pressure supplied to the braking system until the wheel begins to accelerate again. When the acceleration is detected the pressure is again increased until an unusual amount of deceleration is detected. This paper presents the formulation of a slip control model for purposes of performing slip tracking of target slip. The design of an anti-lock braking system controller, that automatically minimizes the braking distance by adjusting the braking torque in response to the wheel slip, is develop for multi body vehicle model. Most of the anti-lock braking system controllers developed were aim to maintain the wheel slip at a desired value. This requires accurate measurement of the wheel slip. So, we need to control the brake torque to the optimum longitudinal slip to avoid wheel from locking.
