智能车模型是以一个四轮车模为基础,以一片MC9S12XS128MAL芯片智能车的微控制器,利用CCD信号检测道路基本信号,实现自定义行车轨迹及其以黑色引导线(本课题宽度为25mm)作为引导方式下完成的行驶过程,行车轨迹必须在6m×8m的场地完成,且必须有五个以上的弯道,其中包括三个直角弯道和两个180°弯道;利用单片机输出PWM脉冲和驱动控制舵机和电机的转向和转速,使小车能够安全行驶于预先设计好的路线,并且能在终点处自动停车。
The smart car model is based on a four-wheel car model, with a MC9S12XS128MAL chip smart car microcontroller, the use of CCD signals to detect basic road signals to achieve a custom driving trajectory and its black guide line (the width of 25mm) as Guided completion of the driving process, driving trajectory must be completed in the 6m × 8m site, and must have more than five corners, including three right-angle corners and two 180 ° corners; the use of single-chip PWM pulse output and Drive controls the steering and speed of the servos and motors to allow the car to travel safely on a pre-engineered route with automatic parking at the end point.
