ABSTRACT

In this paper, the hardware index design of EPS system based on functional safety is deeply studied and analyzed. In the process of car driving, EPS system plays a crucial role, it improves the driving stability and handling by controlling the steering force of the vehicle. Under the requirement of functional safety, the hardware index design of EPS system is very important. First of all, this paper gives an overview of EPS system, introduces its basic principle and functional safety requirements. Then, we focus on hardware index design, including hardware architecture design, signal processing design and circuit protection design. Through the research and analysis of these aspects, this paper puts forward some effective methods and strategies to meet the requirements of EPS system under functional safety. Finally, the performance of the system is analyzed, including functional safety performance evaluation, reliability analysis and fault tolerance design.
