Description

Technical Field

[0001] The invention relates to the technical field of automobile radar testing, and in particular to a matching testing device for automobile radar and bumper. Background Art

[0002] As one of the important sensors of Advanced Driver Assistance System (ADAS), automotive radar has become an indispensable part of ADAS system. With the continuous development of autonomous driving technology, automotive radar will have a huge market demand. Usually, automotive radar is installed on the inside of the bumper. The shape, material, relative posture of the bumper will affect the wave transmission performance of the automotive radar. Therefore, in the development of automotive radar products, the matching test method between automotive radar and bumper is an extremely important part.

[0003] At present, there are three main methods for testing the matching between automotive radar and bumper:

[0004] The first method is to directly fix the radar and bumper with fixtures. The disadvantage is that the radar and bumper are connected by fixtures and cannot be adjusted in any way. The radar and bumper are completely fixed. When the relative posture of the radar and bumper changes, a new set of corresponding fixtures must be made, which is costly and inflexible.

[0005] The second method is to fix the radar, and adjust the relative posture of the bumper to the radar through four adjustment screws fixed relative to the radar. The disadvantage is that the precise position of the bumper cannot be adjusted by adjusting the screws, unless precise mathematical calculations are performed before each adjustment, and the rotation angle of the adjustment screw is strictly controlled. Therefore, the adjustment is also inconvenient.

[0006] The third type is to fix the bumper and change the relative posture of the radar and the bumper by adjusting the position of the radar. The problem with this tooling is that although it is relatively easy to adjust the radar posture, every time the radar is adjusted, the coordinate system of the corresponding radar test system must also change with the radar, and this change is usually more difficult, which brings another difficulty to the test.
