汽车电子转向技术发展与展望

汽车电子转向系统是一种全新概念的转向系统，其取消了转向盘和转向车之间的机械连接，通过软件协调它们之间的运动关系，可以实现一系列传统转向系统无法实现的特殊功能。它可以实现传动比的任意设置，并对随车速变化的参数进行补偿。并且可以和ABS、汽车动力学控制、防碰撞、单个车轮转向、轨道跟踪、自动侧向导航等功能相结合，实现对汽车的整体控制。综述了国外汽车电子转向技术的研究现状，介绍了电子转向系统的结构及性能特点，阐述了电子转向系统的关键技术、主要问题及解决方法，并展望了电子转向系统的发展趋势。

Development and Forecast of Automotive Electronic Steering Technology

Automotive electronic steering sys te m is a complete new concept in steering system,the mechanical con-nec tions b etween steering wheel and turning vehicle wheel are eliminated,motion relations hip can be coordinated between them by software and a series of special function s can be realized for which can not be realized by the traditional steering syst em.It can realize the freedom setting up of driving ratio and can compensate th e parameters with vehicle speed varia-tion.It can combine with the functions o f ABS,automotive dynamic s control,anti-collision,single wheel turning,trac k tracing and automatic lateral navigation,etc.to realize a whole control of a vehicle.The paper describes present research status of automotive electronic steering technologies in foreign countries,introduces the structure and perform ance of electronic steering system,explains the key technologies,main problems and troubleshootings of electronic steering system and fore-casts the develop ing trend of electronic steering system.
