飞思卡尔智能车控制代码，我们做的是变形三轮直立组，目前只有三轮状态下的运动控制代码，PID参数需要结合自己车模的结构参数做相应的调整，速度环和方向环均采用的是位置式pid算法。(Freescale Intelligent Vehicle Control Code, we do deformation three-wheel vertical group, currently only three-wheel motion control code, PID parameters need to be adjusted with the structural parameters of their own model, speed loop and direction loop are using position PID algorithm.)
