Automatic steering control method for pure electric vehicle

The invention belongs to the technical field of automatic control of pure electric vehicles, and particularly relates to an automatic steering control method for a pure electric vehicle. A system carried by the method comprises a central control module, a road condition acquisition module, a vehicle speed detection module, a steering wheel rotating speed detection module, a size adjustment driving module and an extension structure driving module, and a steering wheel is controlled to perform different telescopic changes based on different deflection angles of a driving road section, so that the driving safety and the driving visual field are considered; based on different traffic flows and different vehicle speeds, a steering wheel telescopic structure and a size adjusting mechanism are controlled to act, and driving safety is guaranteed while supporting is provided for a driver; based on different steering directions, a steering wheel is controlled to act to provide support for a driver so as to balance cent
