Abstract

Freescale MC9S12DG128 16-bit MCU (micro controller unit), as the core control unit, constitutes a intelligent car system with DC motors, steering gear and power source, as well as other circuits, The system has designed hardware and software, and realized the real-time observation for the car through PC. MCU uses PID algorithm to realize real-time control to the angle of steering gear and marching speed. The program has a good real-time performance, which has achieved the result that the car can run rapidly and accurately independently; furthermore, it owns characters of strong anti-interference, small steady-state error and so on.
