摘要
本文介绍了乘用车电控转向系统的发展概况。转向系统是汽车上驾驶者与其紧密接触的操控装置,其发展应考虑人因工程和驾驶安全两个方面。转向系统电控化是汽车技术发展对转向系统提出的必然要求,也是提高驾驶舒适性和安全性的基本途径。按照电控转向系统的发展历程,本文综述了电动助力转向系统、前轮主动转向系统、前轮线控转向系统以及后轮线控转向系统的结构及工作原理、关键技术以及进一步发展所面临的挑战;从结构简洁、布置方便、修正驾驶者过渡操作等方面来看,线控转向系统是电控转向系统的发展趋势。
This paper introduces the development of passenger car steering systems with electronic control. Steering system is the operation device on vehicle with which the driver will get in touch the vehicle. Ergonomics and drive safety should be taken into account in the development of vehicle steering system. Electronic control of the steering system is a tendency of the development of passenger car technology and a basic way to increasing the drive safety and comfort. This paper summarizes the structure and working principle of electric power steering system, active front steering system, front wheel steer-by-wire system and rear wheel steer-by- wire system respectively in accordance with the progress history of electronically controlled steering systems. Also, the paper sketches the key technologies, advantages and challenges to be faced of the above-mentioned steering systems. Finally, it concludes that steer-by-wire system will be the development trend of electronic control steering system from the point of view of concise construction, convenient layout and correcting driver＇s over operation.
