A brake strategy for an automatic parking system of vehicle

The purpose of this research is to develop a braking strategy for an automatic parking system, including the brake controller design, simulation results and system validation. The development of brake control strategy is divided into two parts: PI and Fuzzy-PI control schemes. In addition to the design of controllers, a speed trajectory consisting of acceleration, constant speed, and deceleration is planned in order to provide the driver more comfortable feeling. The simulation is performed in a developed vehicle longitudinal Matlab/Simulink model to observe the response of the overall system. In the system validation, a brake actuator with a microprocessor is equipped and implemented in our experimental platform. The simulated and experimental results indicate that the proposed brake controller can work properly with this automatic parking system and make the process of parking smooth and stable.
