1. 研究目的与意义（文献综述）

new energy's pure electric vehicles andsmart vehicles with internet of vehicle have become the two main developingdirections. steer-by-wire (sbw) technology of automobiles is a key technologyfor the development of pure electric vehicles and smart vehicles. it not onlyimproves the handling stability of automobiles, but also can be integrated andcontrolled with other control systems of vehicles to make the car moreintelligent.

1. it is an inevitable need to improvehandling stability of automobiles.
