摘要
传统的液压助力转向系统只能提供有效的转向助力,但不能根本地解决汽车驾驶员操纵"路感"不足的问题。文章介绍了汽车电动助力转向系统(EPS)的构成、分类、主要特点及未来发展方向。说明了EPS不但可以提供轻便和灵敏的操作,而且可以提供良好的"路感"。通过对EPS的结构和原理分析,指出EPS是未来汽车技术发展的必然趋势。
Traditional hydraulic power steering system only provides effective steering, but cannot give a ‘road feel’ to driver. This article introduces the structure, principles, features and future development of automotive electric power steering. It is showed that EPS can provide perfect‘road feel’ besides light and sensitive operation. By analyzing the structure and principle of EPS, it is indicated that EPS will be the inevitable trend of auto development in the future.
