Idle parking space identification method and device and vehicle

Abstract

The invention provides an idle parking space identification method and device and a vehicle. The method comprises the steps of: periodically collecting a first distance between obstacles at two sides of a vehicle body and the vehicle body in a process that the vehicle runs in a direction perpendicular to a parking space; generating vertical coordinate data of the obstacle according to the first distance, generating horizontal coordinate data of the obstacle according to a second distance of vehicle driving in two adjacent acquisition processes, and acquiring a plurality of coordinate points of the obstacle according to the vertical coordinate data and the horizontal coordinate data of the obstacle generated in sequence; determining whether the obstacle is another vehicle according to whether the plurality of coordinate points are matched with a preset curve; and when determining that the obstacle is another vehicle, judging whether an idle parking space exists around the obstacle according to a preset parking space search algorithm. According to the idle parking space identification method and the device, whether the obstacle is the vehicle or not is judged to confirm that the parking space boundary is the idle parking space perpendicular to the vehicle driving direction of the vehicle, and correct parking of the vehicle is achieved.

Description

technical field [0001] The invention relates to an automatic parking or valet parking system, in particular to a method, device and vehicle for identifying a vacant parking space. Background technique [0002] In order to free users from complicated parking operations and avoid various misoperations and accidents when users park manually, various related companies are developing automatic parking or valet parking systems. At the same time, in the process of automatic parking or valet parking, in order to reflect the intelligence of the system, the parking spaces in the parking lot should be correctly identified, so how to accurately confirm the parking spaces is a crucial step. [0003] At present, the method for identifying a parking space is as follows: the user drives in the parking lot and searches for a parking space, and parks the vehicle after searching for a parking space. However, in the prior art, the general method for ultrasonic radar to identify empty parking s...
