智能寻迹车在工业领域具有广泛的用途,智能寻迹车的运行速度和稳定性直接影响到系统的工作效率.为了提高系统的运行速度与稳定性,设计并实现了一种基于高性能的Freescale S12系列微控制器的智能寻迹车.采用激光传感器探测黑色路径的位置,通过对电机调速模块、传感器随动舵机控制模块和前轮转向控制模块的研究,提出了一种传感器随动的寻迹控制策略,实现了小车自动沿黑色路径行驶.经测试智能车速度快,跟踪黑色路径准确.

The intelligent tracing car are widely used in the industry, its efficiency and stability are important to an intelligent system. In order to improve the running velocity and stability, the intelligent tracing car adopt on a high-performance MCU named Free：~cale S12. It uses laser sensors to trace black route. According to research about the motor and steering engine, a lane detection control strategy is creatively presented based on the sensors servo. The experiment shows that the intelligent tracing car can accurately trace the black route with high velocity.
