本文并初步探讨了汽车运动的控制算法,包括横向控制算法和纵向控制算法, 并建立起汽车运动控制系统的简化模型。在MATLAB 环境下对汽车运动控制系统进行PID 和根轨迹的设计和校正。由此，确定汽车运动控制系统的期望静态指标（稳态误差）和动态指标（超调量和上升时间）。该方法简便快捷，结果准确可靠，它是汽车运动控制系统设计的优秀手段之一。

Abstract: The paper describes a control algorithm of Automobile Motion, including horizontal control algorithm and longitudinal control algorithm and then set up the simple model of auto kinetic control system. Auto kinetic control system was adjusted by PID and roots locus methods in the condition of MATLAB. There out, the static index (steady- state error) and the dynamic index (overshoot and rise time) of auto kinetic control system can be fix on. The method is simpler and more convenient, and the result is more precise and reliable, the method is excellent in the design of auto kinetic control system.
