BUILDING A MODEL FOR TRACTION CONTROL USING AN ABS BRAKE ACTUATOR

Abstract

In the anti-lock braking system, the brake actuator plays an indispensable role, regulating brake fluid to the brake cylinders on the wheels to perform the braking process following the system’s requirements. Regulating brake fluid is a crucial and complex job that affects the effectiveness of the braking process as well as the traction control system of the brake actuator on the vehicle. In this article, the solution to control the brake actuator is proposed based on the control mode of the valves inside it, ensuring that the braking process on the wheels is consistent with their rolling state on the road surface, thereby controlling traction on the active wheels. To achieve this goal, the movement speed of the valves in the actuator and the brake fluid pressure at the wheel cylinders must be controlled by a special control algorithm. In addition, several model parameter variables are also considered. Simulation results are shown to demonstrate the effectiveness of the proposed control law.
