【Abstract】 The electric power steering system, as a key system for vehicle lateral control, is built on the traditional hardware(mechanical structure) of car steering, with high sensing sensor components, efficient software control strategies, and precise motor assisted control as the core technologies to achieve intelligent car steering and promote the development of steering technology towards a more advanced and intelligent future. Research on the sources, principles, strategies, and influencing factors of end protection function, combined with the end protection problems that occur in actual vehicles, analyzes the three factors that affect end protection function, and formulate optimization measures. And through the collection of a large amount of data and subjective evaluation verification of actual vehicles, the study determines that the optimization measures are effective and achieve the optimal steering performance.更多还原
