Device and method for data acquisition of automatic parking library search test based on ultrasonic radar

Abstract

The invention belongs to the field of automatic parking test equipment and relates to an ultrasonic radar-based automatic parking and space searching test data acquisition device and method. The acquisition device is composed of a vehicle simulation device, a guide rail device and a central control unit. The pitch angle of the ultrasonic radar, the projection angle on a horizontal plane, the guiderail angle and the speed of the vehicle simulation device are set by the central control unit, the height of the ultrasonic radar is set manually, automatic parking and space searching tests under various conditions are carried out and corresponding data are recorded. In comparison with the prior art, the manual test burden can be greatly lessened, the movement of the test equipment can highly coincide with a preset test condition, the test precision is improved, the height, the direction and the angle of the radar can be switched randomly and conveniently, and the test efficiency can be effectively improved.

Description

technical field [0001] The invention belongs to the field of automatic parking test equipment, and in particular relates to a data acquisition device and method for an automatic parking library search test based on ultrasonic radar. Background technique [0002] At present, many vehicle manufacturers and universities in my country are vigorously developing automatic parking technology. Among them, the method of detecting parking spaces through ultrasonic radar has been widely used at a low price. The basic principle of automatic parking is assuming that there are cars in front of and behind a certain parking space, and the self-car drives forward outside the parking space, and the parking space is detected by ultrasonic radar. However, for different parking spaces and different ways of moving the vehicle, the characteristics of the storage space detected by the ultrasonic radar are different. If you want to find the parking space accurately, you must optimize the library sea...

AI Technical Summary

Problems solved by technology

However, for different parking spaces and different ways of moving the vehicle, the characteristics of the storage space detected by the ultrasonic radar are different. If you want to find the parking space accurately, you must optimize the library search algorithm through a large number of library search experiments. verify

The current test method generally uses the driver to drive the vehicle to detect various storage locations with different movement methods, which is not only time-consuming and laborious, but also it is difficult for the driver to drive the vehicle completely according to the preset test conditions, and the test accuracy is not high.

In addition, the installation height and angle of the ultrasonic radar are also crucial for warehouse location detection. It is very inconvenient to directly install the ultrasonic radar on the vehicle, and it is very inconvenient to adjust these parameters later.
