Description

technical field

[0001] The invention belongs to the technical field of electric vehicle driving, and in particular relates to a steering-by-wire and EPS technology. Background technique

[0002] The steering system of a car can control the driving direction of the car according to the driver's intention, and the steering system of a car plays a vital role in driving safety. The hydraulic power steering system with traditional mechanical structure is very mature, providing the driver with good steering convenience. However, the hydraulic power of the traditional mechanical hydraulic power steering system must rely on the engine to provide power. If it is used in an electric vehicle, a hydraulic drive device must be installed to increase the complexity; therefore, for electric vehicles, the EPS technology This problem has been solved to a certain extent; and the traditional steering system mostly adopts the rack and pinion steering gear structure, which not only transmits the...
