Abstract

The invention provides an automatic driving method for automatic parking and charging of an electric vehicle, and belongs to the field of automatic driving parking. According to the automatic driving method, through a pre-established parking lot high-precision map, after a vehicle enters a selected parking lot, the parking lot high-precision map is loaded according to a vehicle GPS signal, whether the vehicle needs to be charged or not is automatically detected, a parking space is selected, the position of the vehicle and the position of a target parking space are combined with the high-precision map of the parking lot to plan a driving path, and the vehicle is automatically parked in the target parking space after being automatically controlled to drive to the target parking space according to the driving path, so that the vehicle can be effectively controlled to complete parking conversion between automatic parking and charging, accurate parking of the vehicle is facilitated, and a driver does not need to wait and charge the electric vehicle.

Description

technical field [0001] The invention belongs to the technical field of automatic driving and parking, and in particular relates to an automatic driving method for automatic parking and charging and replacing of electric vehicles. Background technique [0002] The autonomous parking system is a solution to the problem of automatic driving of the vehicle from the entrance of the parking lot to the parking space. The traditional autonomous parking system establishes a high-precision map of the parking lot, and uses the on-board computing unit and on-board sensors to realize environment perception, path obstacle avoidance, and parking space search, thereby realizing automatic cruise parking. The real-time positioning system in autonomous parking generally uses on-board sensors, such as surround-view cameras, forward-looking cameras, and millimeter-wave radars. The information extracted by the sensors is compared with the high-precision map to realize the positioning of the vehic...
