Problems solved by technology

[0003] In the process of realizing the present invention, the inventors found that most of the existing calibration tools are calibration tools for a single car model, that is, a calibration tool can only calibrate the vehicle radar of a single car model, and at the same time, the calibration method relies too much on software to calculate the offset angle, which needs to be repeated. It takes multiple calibrations to complete, which is cumbersome and inconvenient to use

Embodiment Construction

[0094] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is said to be "fixed" to another element, it may be directly on the other element, or there may be one or more intervening elements therebetween. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The terms "vertical", "horizontal", "left", "right", "inner", "outer" and similar expressions are used in this specification for the purpose of description only.

[0095] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the technical field of the invention. Terms used in the description of the pre...

Abstract

The invention relates to the technical field of automobile maintenance and equipment calibration and discloses on-board radar calibration equipment and a method. The on-board radar calibration equipment comprises a radar calibration plate, a radar calibration laser and a radar calibration reflector. The radar calibration plate comprises a through hole. The radar calibration laser is used for emitting a laser beam to penetrate through the through hole after vertical surface calibration of the radar calibration plate is accomplished. The radar calibration reflector is mounted on a to-be-calibrated on-board radar of an automobile and reflects the laser beam penetrating through the through hole back to the through hole along the original path to achieve the calibration of the on-board radar. According to the equipment, the radar calibration reflector can be mounted on the on-board radar of different automobile types; after a vertical surface of the calibration plate is calibrated, the radar calibration laser emits the laser beam to penetrate through the through hole; the radar calibration reflector reflects the laser beam penetrating through the through hole back to the through hole; the equipment can perform calibration operation on the on-board radar of the different automobile types; and the calibration work of the on-board radar is facilitated.

Description

【Technical field】 [0001] The invention relates to the technical field of vehicle maintenance and equipment calibration, in particular to a vehicle-mounted radar calibration equipment and method. 【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 determine the c...
