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.
