Description

Parking method and device and new energy automobile Technical Field The application relates to the field of intelligent driving and vehicle-mounted man-machine interaction intersection, in particular to a parking method and device and a new energy automobile. Background The prior art has poor hysteresis, only considers whether a vehicle can enter a parking space for parking, lacks consideration for safe getting off of passengers, only detects a door opening space after the vehicle is stationary, cannot pre-judge whether the passengers can get off safely before parking, and has early warning defects. If the parking space is narrow, the situation that the driver or other passengers cannot get off the vehicle safely after parking possibly exists, so that the driver needs to readjust the vehicle position, and the efficiency is low. Meanwhile, the decision logic in the parking process in the prior art is single, the limitation is strong, only whether the vehicle can be parked in the parking space is taken as a judgment standard, the difference of the sizes of passengers and the getting-off requirement of special groups (such as children, disabled people and the like) are not considered, the situation that the passengers get off difficultly or cannot get off is easily caused, and further the parking is impossible.
