大众动态全轮转向系统浅析

Analysis of VW Dynamic All Wheel Steering System

大众动态全轮转向系统可以解决汽车对于低速时和高速时对转向系统性能要求相矛盾的需求,采用动态全轮转向系统可以根据速度调节转向传动比来提高车辆的操纵稳定性和灵活性。文章研究了大众奥迪动态全轮转向系统的结构组成,重点学习其软件调节系统的工作原理,分析了底盘控制单元中各软件间的数据共享,以做到不同速度下精准控制转向轮的转向角,以达到低速时降低转向传动比增加转向的灵活性,高速时增加转向传动比提高转向的安全稳定性,大大改善车辆的行驶动力学性能。

The dynamic all wheel steering system combines the dynamic steering system with the rear wheel steering system.The traditional steering tie rod in the front wheel steering system is replaced by an actuator.The rear wheel is equipped with a steering control device.For the vehicle equipped with this system,the driver can independently control the steering angle of the front wheel and the rear wheel,which are independent of each other.Finally,the front and rear axles can be adjusted.The system can achieve accurate steering angle and greatly improve the driving dynamics performance of the vehicle.
