摘　　要：目前国内外生产的低、中档轿车普遍采用恒定助力的动力转向系统,但国外生产的高档轿车已经引入按车速与转向盘转速或转矩自动变助力的电控液压动力转向系统或电动助力转向系统,上海大众生产的Polo轿车也装配了电控液压助力转向系统。以Koyo公司研制的EHPS系统和上海大众Polo轿车装配的EHPS系统为例,研究EHPS系统的结构、工作原理以及控制原理。The steering system is one important subsystem of a car. As a result, the capability of the steering connects with handling stability and driving comfort. Traditional mechanical steering and hydraulic power steering cannot satisfy the rising requirements on handling stability and driving comfort. Electrical hydraulic power steering (EHPS) developed by Koyo has many advantages over traditional hydraulic power steering, such as saving energy and superior capability. The car Polo made by Shanghai VW is equipped with EHPS. This paper presents the configuration, operation and control principle of EHPS.
