摘要
以MC9S12DG128为控制器,设计了一种智能车系统。该系统由路面检测模块、测速模块、电机驱动模块、电源模块组成,是一个集环境感知、规划决策、自动驾驶等多种功能于一体的综合系统。在控制算法上采用了PID控制算法,它可以自动调节PWM波的占空比,从而控制小车的速度。
MC9S12DG128 is used as controller to design an intelligent vehicle system. The system makes up of road monitor module, testing velocity module, moving motor module and electricity module, including collecting information, make a decision, automatic driving and so on. The system adopts PID algorithm which can automatically modulate duty cyele and period, and controls velocity further.
