摘要
作为线控转向技术的应用场景之一,四轮转向(4WS)技术能够改善车辆低速行驶的灵活性和中高速行驶的操纵稳定性。文章主要从4WS结构方案、控制策略和失效容错方案3个方面进行文献综述,分析当前汽车4WS技术中的主要研究方法和成果,为进一步研发安全可靠的四轮转向系统提供借鉴。
As one of the application scenarios of SBW technology,four-wheel steering(4WS)technology can improve the flexibility of the vehicle at low speed and the handling stability at high speed.In this paper,the 4WS schemes,the 4WS control strategies and the 4WS fault-tolerance designs are reviewed,the main research methods and achievements in the current 4WS research are analyzed,in order to provide reference for the further development of 4WS system.
