Automobile reversing radar display instrument testing system and testing method thereof

Abstract

The present invention provides an automobile reversing radar display instrument testing system and a testing method thereof. The automobile reversing radar display instrument testing system includes an upper computer and a signal generating module. The signal generating module includes a communication module for generating simulated automobile reversing radar signals, a data acquisition device, and a plurality of board cards inserted in the data acquisition device. The upper computer includes a display device, a device communication module, and an information processing device. The testing method can replace an ordinary automobile reversing radar sensor, wherein, the ordinary automobile reversing radar sensor transmits high-low level signals to an instrument, and does not require to verify automobile reversing radar instrument display by manual adjustment of automobile reversing radar position so that the real automobile verification is reduced and the verification cost is reduced.

Description

technical field [0001] The invention relates to a display test system and method, in particular to an automobile reversing radar display instrument test system and a test method thereof. Background technique [0002] At present, instruments with reversing radar display are becoming more and more common. For the research and development of this kind of combined instrument, it is particularly important to test the reversing radar. Many automotive reversing radar communication modules on the market transmit high and low level signals, and are generally installed. A reversing radar sensor. [0003] In the prior art, there are mainly two methods for verifying the display of the reversing radar on the instrument. One is to verify whether the reversing radar display of the instrument is correct by performing real vehicle verification; , only test the display of the parking radar function on the instrument. Method 1 is difficult to judge the distance between the reversing radar an...

AI Technical Summary

Problems solved by technology

Method 1 is difficult to judge the distance between the reversing radar and obstacles, and the actual vehicle verification has certain risks and high cost

The second method is artificially difficult to control multiple sensors, and the operation is cumbersome. It is impossible to truly and accurately simulate the distance between the reversing radar sensor and the obstacle. The improper placement of multiple sensors may easily cause interference.

And neither of these two methods can flexibly combine various vehicle conditions for sufficient testing
