Parking target parking space generation and updating method and device

The invention relates to the technical field of automatic parking, in particular to a parking target parking space generating and updating method and device. The method comprises the following steps: entering a parking space searching mode, and generating an initial parking space and an initial drivable area by using a side radar; and starting a parking in-place mode, and in the process of parking in the corresponding parking space through the driving area, updating the data of the parking space and the driving area by using the rear side radar alone or the side radar is matched with the rear side radar. Automatic parking and valet parking functions of different platforms and different sizes of vehicle models can be adapted, and space parking spaces meeting automatic parking requirements in various scenes can be generated; by means of the secondary updating method, the parking space angle can be output more accurately, the parking space coordinate precision can be improved more accurately, re-planning parking
