Anti-lock braking system (ABS) is an automobile safety system that allows the wheels on a motor vehicle to maintain tractive contact with the road surface according to driver inputs while braking, preventing the wheels from locking up and avoiding uncontrolled skidding. The dynamics of the controller needed for antilock braking system depends on various factors. The vehicle model often is in nonlinear form. Controller needs to provide a controlled torque necessary to maintain optimum value of the wheel slip ratio. The slip ratio is represented in terms of vehicle speed and wheel rotation.
In this research study of Matlab ABS model developed for single wheel is carried out and results are obtained for the same. To obtain the complete four wheel simulation CARSIM simulation software is used. The complete ABS model is developed for the hatchback and van segments car and results of both the simulation softwares are compared.
