Problems solved by technology

In order to take into account the recognition of the roadside and the detection of vertical parking spaces, long-distance and long-distance detection is used in the market. The disadvantage is that the number of detections per unit time is small, the number of scanning points is not enough, and the contour of the parking space may not be scanned finely enough, resulting in the parking space. The detection accuracy is not enough, which affects the parking effect

Abstract

The invention provides a method for improving the accuracy of the outline of a parking space and an automatic parking system. The method includes using a detection device of the vehicle to measure the distance between the vehicle and the obstacle multiple times in real time; Measuring the distance between the moving vehicle and the obstacle to obtain the same or similar parking space contour data as the contour of the actual parking space edge; identifying the parking space according to the parking space contour data. The automatic parking system of the present invention adopts the above-mentioned method to realize automatic parking. The invention can increase the detection speed without affecting the original function, increase the number of scans, obtain more detection data, and shorten the detection time.

Description

technical field [0001] The invention relates to the technical field of ultrasonic measurement, in particular to a method for improving the accuracy of a parking space contour and an automatic parking system applying the method. Background technique [0002] In the automatic parking radar system, in order to detect the road edge, the general detection depth is opened to a position of about 5 meters, so that each detection cycle will be longer, the number of scanning times of the parking space will be less, and the detection data obtained will be less, which is not conducive to the vehicle. Contour data analysis may result in insufficient parking space contour accuracy. In theory, the more data, the more accurate the analyzed data, and the more accurate the obtained parking space contour. [0003] At present, the parking space identification of ultrasonic automatic parking system basically relies on transmitting ultrasonic scanning. In order to take into account the identific...
