Automatic parking system and method using universal probes

Abstract

The invention discloses an automatic parking system and method using universal probes, and relates to the technical field of automobile auxiliary systems. The system comprises an automatic parking controller and a plurality of probes of the same type, and the probes are arranged at the front end, rear end, corners and side surfaces of an automobile respectively; the probes arranged at the cornersand the side surfaces detect a parking space, and the probes are changed from two types to one same type; great convenience can be provided for production without distinguishing different parts, and related part design and fool-proof and separated management of production and inventory are omitted; the product detection accuracy (in parking space scanning) is greatly improved, and the automatic parking performance can be significantly improved; through the adoption of the same type of universal probes, the product system cost, management cost, quality cost and maintenance cost are reduced.

Description

technical field [0001] The invention relates to the technical field of automobile auxiliary systems, in particular to a probe universal automatic parking system and method. Background technique [0002] At present, more and more mid-to-high-end models on the market have begun to be equipped with ultrasonic automatic parking functions, such as Volkswagen Magotan, Hao Rui; GM Envision, Cruze; Ford Maverick, etc. Under the vigorous publicity of various automakers, users gradually understand and accept that they will pay attention to whether this function is equipped when purchasing a new car; OEMs are generally planning APA automatic parking functions for new models currently developed, and mass-produce models in the next 2 to 3 years The configuration rate will be significantly improved. [0003] There are two main technical solutions for the automatic parking system, which are ultrasonic sensor-based detection technology solutions and image recognition-based detection techno...

AI Technical Summary

Problems solved by technology

[0013] In the existing technology, the production, inventory, installation and management of two probes are more complicated than one probe, which requires foolproofing and increases the management cost and quality cost; in addition, if Figure 4 As shown in the middle picture (a) and picture (b), a single APA probe is used for single-transmission and single-reception parking space detection. Due to the umbrella-shaped propagation and detection characteristics of the ultrasonic wave itself, the detection accuracy of this scheme is relatively low, resulting in false detection and missed detection. high probability;

[0014] In addition, if Figure 5 As shown, 1 in the figure represents an obstacle. The traditional distance measurement method is: the side APA Sensor adopts self-sensitivity and self-reception, and the distance measurement takes the Sensor as the center of the circle. All obstacles at equal radius distances feed back the same distance information. Therefore, this scheme can only detect how far the obstacle is on the circumference of the Sensor, but cannot accurately determine the specific location of the obstacle.
