The full English name of EPS is Electronic Power Steering, which refers to the electronic power steering system. It uses the power generated by the electric motor to assist the driver in power steering. The steering system, as an important component of the entire vehicle, is one of the key systems that affect the handling stability, comfort, and driving safety of the vehicle.

In the design of steering systems, in order to alleviate the contradiction between vehicle steering portability and steering sensitivity, most commercial vehicles and 50% of sedans use power steering systems. Since the 1950s, the power steering system has gone through three development stages: conventional hydraulic power steering system (HPS), electro-hydraulic power steering system (EHPS), and electric power assisted steering system (EPS), and there is a trend towards electronic and intelligent development.

From a global perspective, the loading rate of automotive EPS has exceeded 50%. About 63% of passenger cars in China use HPS and 35% use EPS, while the EPS loading rate of domestic brand cars is only about 20%, indicating huge potential for future development. Since 2015, China has surpassed Europe, America, and Japan to become the world's leading EPS market.
