Zhenghe Chen, Xizhi Hu, Yan Li, Zhaoyuan Zhang · 2017
A general structure of motor-brake pedal is put forward to solve the problem of automatic parking system for intelligent driving on traditional fuel vehicles. At the same time, as the large fluctuation of conventional PID control and the parameters of PID cannot be changed in realtime, fuzzy-PID control method is used to control the rotation angle of the pedal. Firstly, the structure of the pedal is designed to replace the original control mechanism. Then the fuzzy controller is designed and the vehicle model and control model are established. By comparing the simulation results of fuzzy PID control and PID control, it is proved that fuzzy PID has better control effect. Finally, the whole has been proved to be effective and stable by the real vehicle test.
