Desirable performance of Anti-lock braking system for any kind of road with its specific qualities in a certain amount of slip occurs, Thus regulation the optimum wheel slip leading to better performance and the car without locking the wheels stopped in a short time after braking. Anti-lock braking system is a nonlinear system with uncertainties, based on the quality of the road which makes it difficult to control wheel slip. The purpose of this paper is designing the sliding mode controller for independent control of vehicle wheels slip or in other words regulate the wheel slip to the reference slip. In this paper, we have presented a model of car with four wheels and the purpose is independent control of each wheel slip. In the evaluation phase of designed controllers, CARSIM simulator has been used which is one of the most prestigious simulator and used the real model of the car. The simulation results show better performance of the controller designed with the method of sliding mode control compared to the conventional methods.
