Abstract

The invention, which belongs to the technical field of automobile electronics, discloses an automatic calibration device and method for the mounting angle of a vehicle-mounted millimeter wave blind zone monitoring radar. The automatic calibration device comprises a radar calibration control module, a radar calibration processing module and a CAN bus device. The radar calibration control module isused for setting a radar working mode and calibration parameters. The radar calibration processing module is configured to complete the processing work of radar calibration parameters and data. The CAN bus device is used for completing communication connection work between the calibration device and the radar. The radar calibration control module and the radar calibration processing module are electrically connected to the CAN bus device. According to the invention, installation requirements of the a vehicle-mounted millimeter wave radar blind zone monitoring system by different vehicle manufacturers and different vehicle models can be met in a self-adaptive manner; and the relevant calibration parameters are adjusted by the automatic calibration device; a radar installation angle calibration problem after mass-produced vehicle type radars of the whole-vehicle-factory production line is solved effectively; and the usage demand of the radar by the user is satisfied.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a device and method for automatically calibrating the installation angle of a vehicle-mounted millimeter-wave blind spot monitoring radar. Background technique [0002] In today's automobile industry, the driving safety of vehicles is getting more and more attention, and it has become the main selling point of major automobile manufacturers. In the process of driving a vehicle, the rear of the vehicle is the driver's blind spot. Therefore, when changing lanes at high speed, overtaking vehicles behind, and reversing at low speeds, traffic accidents will cause casualties. The vehicle-mounted millimeter-wave radar blind spot monitoring system can detect the distance, relative speed and orientation of the target. , and has the advantages of high operating frequency, short wavelength, small antenna size, strong adaptability, and can work normally in the dark. At presen...
