COMPARISION OF VEHICLE PERFORMANCE WITH & WITHOUT ANTI-LOCK BRAKING SYSTEM

Abstract

An Antilock Brake System (ABS) is a closed loop control system thatmodulates the brake torque that is applied to the wheel in order to prevent thecontrolled wheel from becoming fully locked.ABS is among the most important safety systems in a vehicle. In automatichighway system, automatic brake actuation is a very important part of the overallvehicle control system. It prevents the wheel lock-up under critical brakingconditions, such as those encountered with wet or slippery road surfaces and driverpanic reaction (Bosch, 1995). By preventing the wheel lock-up, ABS ensures that thevehicle remains responsive to steering wheel inputs. Reduced stopping distance onaccount of ABS is more evident on wet or slippery road surfaces (Garrick et al.,1998).

This paper describe the implementation of Antilock Braking System using MATLAB/Simulink, & than the comparison of vehicle performance with & without anti-lock braking system.
