A kind of radar test equipment and automobile radar pitch angle test method

Abstract

The invention discloses a radar test device and an automotive radar pitch angle test method, and relates to the technical field of automotive radars. The radar test device and the automotive radar pitch angle test method are targeted to the test efficiency and test accuracy of the automotive radar. The radar test device comprises a support, a horizontal sliding rail is arranged on the support, a vertical sliding rail is connected on the horizontal sliding rail in a sliding mode, the vertical rail is connected with a first driving device, the first driving device can drive the vertical sliding rail to slide along the horizontal sliding rail, the vertical sliding rail is provided with a first test body which can be detected and a second test body which can be detected by the radar, the first test body is fixedly connected with the vertical sliding rail, the second test boy is connected with a second driving device, and the second driving device can drive the second test body to slide along the vertical sliding rail. The radar test device is used for testing the pitch angle of the automotive reversing radar.

Description

technical field [0001] The invention relates to the technical field of automotive radar, in particular to a radar testing device and a testing method for an automotive radar pitch angle. Background technique [0002] Reversing radar, also known as parking radar, is a safety auxiliary device when reversing or parking. It is generally divided into front radar and rear radar. As the casualties and property losses caused by vehicle reversing accidents are increasing year by year, people are more inclined to use technical assistance to prevent accidents, thus promoting the development of motor vehicle radar. The cost-benefit ratio between the economic loss caused by these accidents and the cost of the continuously declining motor vehicle radar fully demonstrates that the reversing radar will be widely used. From an automaker's perspective, radar is another attractive feature for consumers, a potential source of revenue and a competitive advantage. And regulators and the public ...

Problems solved by technology

[0004] At present, the radar detection distance and horizontal opening and closing angle are tested on the real vehicle using the hand-held PVC pipe induction test method, and the pitch angle needs to be tested by moving the PVC pipe vertically. It is difficult for the tester to control the PVC pipe induction test, and the operation error and The relatively large error in the measurement readings makes the numerical test of the radar pitch angle inaccurate, which seriously affects the correctness of the radar function. At the same time, due to the need to repeatedly move the PVC pipe, the labor intensity is high, resulting in a waste of manpower and time.
