Electric Power Steering System Design
ABSTRACT
Automotive electric power steering system is a new type of car steering systems, and compared to traditional hydraulic steering system using electric motors to provide power directly, with many advantages. It can in a variety of driving conditions to provide the best possible help to save fuel, environmentally friendly. In recent years, many in high-end car is equipped with electric power steering system device, EPS studies have become a hot topic in the automotive industry, has important research value and great potential applications. First introduced the design of automotive electric power steering system of the overall layout and working principle of the electric power steering system has done a detailed analysis of components; Then, we introduce the design of electrical main control circuit;In the electric power steering system with the control strategy is highlighted in the study back to working with active damping control strategy,through research, calculations prove slightly,the control strategy can improve the speed of vehicles back positive,inhibition of return when the vehicle speed is overshoot;And in imposing the back after working with active damping control, the driver's control handle has not been adversely affected.
