汽车线控转向系统的现状与发展前景研究

摘要

Wire control steering (Steer-By-Wire,SBW)system refers to the cancellation of the traditional mechanical steering device,which completely got rid of the limitations of previous steering system,without any mechanical connections between steering gear and steering column but through communicating network to connect control system of all parts.The system has good driving motion and quick response time,so it is good for environmental protection and lowing developing costs of chassis.It also can well improve the vehicle's handling stability and the safety of the car.This paper studied the de-velopment of automotive wire control steering system at home and abroad,and introduced the basic structure and working principle of wire control steering and its advantages and the wire control steering technology development prospects.%线控转向(steer-by-wire,简称 SBW)系统指取消了传统的机械式转向装置,摆脱了传统转向系统的诸多限制,转向器与转向柱间没有任何的机械连接,而是通过通信网络连接各部件的控制系统。线控转向系统的转动效率高,响应时间快,利于环境的保护,可降低车辆底盘的开发成本,改善车辆的驾驶特性,可以很大程度上改善车辆的操纵稳定性,提高汽车碰撞安全性和整车主动安全性。本文研究了汽车线控转向系统的国内外发展现状,介绍了该系统的基本结构、工作原理及其特点,展望了线控转向技术的发展前景。
