摘要
汽车的操纵性能决定了汽车的舒适性、安全性等关键性能,而转向系统直接决定了汽车的操纵性能。为了改进汽车转向系统的性能,线控转向技术的控制研究显得尤为重要,文章对于线控转向控制的核心进行介绍,将线控转向系统核心的控制分为三部分,路感模拟控制、主动转向控制、故障诊断与容错控制。详细说明了每一部分目前的研究现状,并对于不同的方法进行了比较分析。最后对于线控转向系统的瓶颈和发展的前景作出了分析。
The car's handling performance determines the car's comfort,safety and other key performance,and the steering system directly determines the car's handling performance.In order to improve the performance of automobile steering system,the control research of steer by wire technology is particularly important.This paper introduces the core of steer by wire control.The core control of steer by wire system is divided into three parts:road sense simulation control,active steering control,fault diagnosis and fault-tolerant control.The paper describes the current research status of each part and the different methods.Finally,the bottleneck and development prospect of steer by wire system are analyzed.
