Radar calibration part and vehicle-mounted radar calibration equipment

Abstract

The invention relates to the technical field of equipment calibration and discloses a radar calibration part and vehicle-mounted radar calibration equipment. The radar calibration part comprises a substrate and a fixing rotating shaft, wherein the substrate is used for reflecting a radar wave emitted from a vehicle-mounted radar of a vehicle to be calibrated to the vehicle-mounted radar after calibration is completed on a vertical surface of the substrate; the substrate is hinged with the fixing rotating shaft; the substrate can rotate around the central axis of the fixing rotating shaft and can at least stop in a first position, a second position and a third position; when the substrate stops in the first position, the substrate is vertically arranged; when the substrate stops in the second position, an included angle is formed between the substrate and a vertical direction; when the substrate stops in the third position, an included angle is formed between the substrate and the vertical direction; the substrate in the second position and the substrate in the third position are in symmetry relative to the substrate in the first position; and the included angle is smaller than a tolerant angle deviation value of the vehicle-mounted radar. By adopting the technical scheme, the adjusting precision of the radar calibration part can be increased.

Description

【Technical field】

[0001] The invention relates to the technical field of vehicle maintenance and equipment calibration, in particular to a radar calibration piece and vehicle radar calibration equipment. 【Background technique】

[0002] In the field of Advanced Driver Assistant Systems (ADAS) in automobiles, Adaptive Cruise Control (ACC) is a commonly used auxiliary function. Its specific working principle is to measure the distance of the vehicle in front in real time through the on-board radar, compare the speed of its own vehicle with the speed of the vehicle in front, and at the same time control the power system of the vehicle such as accelerator and brake, so that the vehicle always maintains a constant distance from the vehicle in front. safe distance. Therefore, the role of the on-board radar is very important in the realization of the ACC function. In addition to the measurement performance of the radar itself, its installation position and installation angle determ...
