Testing device and method for automatic parking system

Abstract

The invention provides a testing device for an automatic parking system. The testing device comprises a parking controller and a test-bench, wherein the parking controller as the main controller of the automatic parking system is placed on the test-bench; a wheel is arranged at the lower part of the test-bench; a wheel speed sensor is arranged on the wheel shaft of the wheel; an ultrasonic wave sensor is arranged on at least one side surface parallel to the test-bench in the moving direction of the test-bench; the wheel speed sensor and the ultrasonic wave sensor are electrically connected with the parking controller; a parking space recognition algorithm, a parking space compensation algorithm, a parking space actual size and various working condition patterns are built in the parking controller used for verifying the accuracy of the parking space recognition algorithm and standardizing the parking space compensation algorithm when the test-bench simulates various parking working condition patterns of automobiles. Correspondingly, the invention provides a testing method applied in the testing device. According to the invention, the testing device for the automatic parking system and the testing method applied in the testing device are low in cost and short in testing time, and can simulate various parking working condition patterns.

Description

technical field [0001] The invention relates to the technical field of automobile active safety, in particular to an automatic parking system test device and a test method. Background technique [0002] With the increase of domestic car ownership, the number of novice drivers is gradually increasing, and the number of parking spaces on both sides of the road is also becoming increasingly tense. Therefore, it is very necessary to make full use of the parking space, which leads to a relatively compact parking space. However, the compact parking space is a big challenge for novice drivers. How to park the car safely in a short time and with few steps is a problem that many novice drivers will encounter. [0003] In order to solve the above problems, the automatic parking technology of automobiles emerges at the historic moment. Moreover, with the rapid development of automotive electronics, the reduction of automatic parking costs and the improvement of electronic control tech...

AI Technical Summary

Problems solved by technology

If the automatic parking system is tested directly with a real vehicle, it will not only cause a huge waste of cost, but also a huge waste of time, and cannot quickly complete the system parking trajectory algorithm (also known as the parking space recognition algorithm) purpose of verification and system performance optimization

In addition, parking space recognition, especially the calculation of the length of the parking space, is crucial to the calculation of the key parking area of ​​the automatic parking system, and the key parking area determines the final parking position of the car. The test cannot meet the system test requirements related to parking space recognition. Specifically, it is limited to the level and ability of the driver. Using a real vehicle to test the automatic parking system cannot meet the requirements of the system in various lateral distances (that is, the distance between the vehicle and the vehicle). the lateral distance between the target vehicle), various speeds, and various longitudinal deflection angles (that is, the longitudinal deflection angle between the vehicle and the target vehicle), that is, the simulation under various parking conditions mock test
