ABSTRACT The incorrect trajectory of cars according to the driver's wishes is one of the main causes of traffic accidents. This paper presents the use of the brake system to stabilize the trajectory of cars. First, an integrated model of a car is proposed, which includes the longitudinal, lateral and vertical motions. Then, the author uses PID control method to design the braking force controller to each wheel to improve the road safety. The parameter considered for the controller design is the deviation of the yaw rate between the actual car model and the ideal one. The simulation results in the time domain clearly show the effect of the proposed controller when reducing survey signals by more than 30% compared to cars without control. Beside that the deviation of the yaw rate is always forward to zero with the short time, which shows that the actual trajectory of the car is almost what the driver wishes.
