Title  Design and Realization of Intelligent Vehicle for the     Freescale Cup —— Hardware Design of the     Photoelectric Sensor Guidance Intelligent Vehicle    Control System based on 32-bit MCU

Abstract This topic is based on the eighth Freescale Cup National University intelligent car contest. According to contest rules, the hardware design of intelligent vehicle control system based on photoelectric guidance has been proposed. And mechanical structure has been adjusted in order to make intelligent vehicle upright on the car models. We use Freescale Coldfire MCF52233 as control core chip to design the entire hardware circuit based on modular thinking, including core control module, power management module, photoelectric sensor module, motor drive module, the speed detection module, human interface module and bluetooth communication module. To ensure the operation performance and reliability of the system, the entire PCB board has been designed according to EMC theory. Finally we complete debugging of every module and the whole system. Actual results show that the system performance meets the design requirements.
