Abstract

The invention discloses an automatic control method and device for locking a power-off parking gear of a pure electric vehicle, and the method comprises the steps that: vehicle power supply information is collected, and the analysis is carried out based on the vehicle power supply information to obtain the power-off intention information of a driver; when it is determined that the power-off intention information of the driver represents the power-off tendency, vehicle operation information is obtained, and whether the vehicle meets a parking gear locking condition or not is judged according to the vehicle operation information; and when it is determined that the vehicle meets the parking gear locking condition, a locking control instruction is generated, and the locking control instruction is used for controlling the driving motor controller to switch the vehicle gear to the parking gear. The vehicle can be automatically controlled to be switched to the parking gear after it is determined that the vehicle is parked and powered off, the anti-theft safety of the pure electric vehicle is guaranteed, the gear of the vehicle after parking and powered off can be adjusted through setting when a driver needs, and then traction of the vehicle in a fault or dormant state can be conveniently achieved.

Description

technical field [0001] The present application relates to the technical field of electric vehicle control, and in particular, to a method and device for automatic control of parking gear lock when a pure electric vehicle is powered off. Background technique [0002] At present, with the development of technology and the demand for energy saving and environmental protection, more and more pure electric vehicles have appeared on the market. Compared with traditional fuel vehicles, pure electric vehicles have an engine anti-theft system because they are powered by igniting and burning gasoline. The engine anti-theft system locks the vehicle to ensure that the vehicle will not slide and be driven away at will. For pure electric vehicles, since they do not have an engine anti-theft system, the parking gear lock is one of the main anti-theft methods for new energy vehicles. The parking gear lock can prevent the vehicle from slipping or moving unexpectedly. However, if the driver...
