Brief Analysis of Dynamic All-wheel Steering System of Audi

动态全轮转向系统是汽车转向系统的新结构。该系统根据实验获得的不同运转条件下的控制方法,并从传感器输入信号判定车辆的行驶状况,计算出执行电机所需要的工作电流,利用改变电动机电流的方向和幅值,向功率控制器发出驱动信号。该系统减少了许多繁杂的机械传动机构,从而降低了成本和重量。它可以协助驾驶员行车,并减轻身体和心理负担。具有转向能力强、转向响应速度、弯道行驶稳定等优点。本文介绍了动态全轮转向系统的基本组成和工作原理,阐述了电子控制动态全轮转向系统对汽车操纵稳定性的影响。

Dynamic all-wheel steering system is a new structure of automobile steering system.According to the control methods under different operating conditions obtained from the experiment,the system determines the running condition of the vehicle from the input signal of the sensor,calculates the working current required for the execution of the motor,and sends the driving signal to the power controller by changing the direction and amplitude of the motor current.The system reduces many complicated mechanical transmission mechanisms,thus reducing cost and weight.It can help the driver to drive,and reduce the physical and psychological burden.It has the advantages of strong steering ability,steering response speed,stable driving on corners,etc.This paper introduces the basic composition and working principle of dynamic all-wheel steering system,and expounds the influence of electronic control dynamic all-wheel steering system on vehicle handling stability.
