Title:
DEVICE FOR DETECTING AXIAL DEVIATION OF RADAR, VEHICLE-MOUNTED SYSTEM COMPRISING SAME, AND METHOD FOR DETECTING AXIAL DEVIATION OF RADAR
Document Type and Number:
WIPO Patent Application WO/2020/054392
Kind Code:
A1
Abstract:
The present invention provides: a device for detecting axial deviation of radar, the device making it possible to detect, before a vehicle travels, axial deviation of radar that is produced while the vehicle is parked; a vehicle-mounted system comprising the device for detecting axial deviation of radar; and a method for detecting axial deviation of radar. The present invention is configured so that an axial deviation detection device 6 performs: a first process for selecting a first reference object that satisfies the conditions of being stationary and not being subject to movement from among first surrounding objects, said selection being made on the basis of first surrounding object data acquired by radar 5 when a driver has exited the vehicle, and selecting and storing the relative position of the first reference object; a second process for subsequently selecting a second reference object that satisfies the conditions of being stationary and not being subject to movement from among second surrounding objects, said selection being made on the basis of second surrounding object data acquired by the radar 5 when the driver has entered the vehicle, and selecting the relative position of the second reference object; and a third process for comparing the relative positions of the first and second reference objects determined to be the same target to thereby detect axial deviation of the radar 5.
