Title:
AXIAL OFFSET DETERMINATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/083515
Kind Code:
A1
Abstract:
Provided is an axial offset determination device comprising: a first detection value acquisition unit for acquiring a first detection value output from a G sensor for detecting acceleration applied to a radar device; a second detection value acquisition unit for acquiring a second detection value output from a YG sensor for detecting the acceleration applied to a vehicle main body; a difference calculation unit for calculating, for each first cycle, a detection difference value which is the difference between the first detection value and the second detection value; an average difference value calculation unit for calculating an average difference value which is the average value of a plurality of detection difference values calculated by the difference calculation unit during an acquisition period which is a period long enough to contain a plurality of the first cycles; a deviation calculation unit for calculating a difference standard deviation, which is a standard deviation for the plurality of detection difference values calculated by the difference calculation unit during the acquisition period; and a determination unit for determining, on the basis of the average difference value and the difference standard deviation, an axial offset produced in the radar device.
