摘　　要：本文采用飞思卡尔公司的MC9S12DG128芯片作为检测和控制的核心,设计并实现了一部能够自主识别路径的智能小车。该系统是由电源管理单元、路径识别电路、车速检测模块、舵机控制单元和直流电机驱动单元5个部分组成。试验证明系统能够很好地满足智能车对路径识别性能和抗干扰能力的要求,可在专门设计的跑道上沿着轨道自主行使,并在稳定的前提下达到一定的速度。In this paper,MC9S12DG128 is used as the control core of the intelligent vehicle which can detect black lines and driver itself in certain race place.There are five parts in this intelligent vehicle,the power source management unit,the way identification circuit,the vehicle speed examination module,the servo control unit and the direct current machine actuates the unit.Experimentation proves that the system can satisfy the requirements of path identifying performance and anti-jamming capability,and it can run along the tracks auto-guided with stable speed.
