| Abstract: | As an emulator of the intelligent auto,the smart car is the basic object for the research of intelligent auto.In this paper,the structure of the smart car was introduced and the hardware and the software were designed.The smart Par control system was designed on the ARM9 core controller and operated in μC/OS-Ⅱ operation system,with the ultrasonic sensor as the navigation.Fuzzy auto-adjusted PID was used as control strategy and the position and the speed are controlled by steer motor and DC motor respectively.The test results indicate that,the smart car had a position track and fast speed switch performance under the control system.This system can be used as the platform for further study of intelligent auto. |
