Automatic parking control method of pure electric vehicle

The invention discloses an automatic parking control method of a pure electric vehicle. A vehicle control unit (VCU) receives various signals of the vehicle, performs logic judgment on different working conditions and controls a hydraulic braking system, a motor control unit (MCU) and a parking pawl driving device as well as instrument information display and P on/off light display. The control method is divided into an uphill control mode, a downhill control mode, a flat-road control mode and a parking control mode. The automatic parking control method of the pure electric vehicle is capable of automatically applying appropriate braking force to the four wheels of the vehicle on a slope or at an intersection for green light, and locking a transmission by use of a parking pawl. When the vehicle starts, the braking force is controlled to be released and the locking of the transmission is cancelled in proper time, and therefore, the automatic parking function is realized and traffic accidents can be avoided. While the functional requirements are met, the vehicle weight is reduced and the vehicle manufacturing cost is reduced.
