Title:
Imperfect alignment determining device
Document Type and Number:
Japanese Patent JP6146285
Kind Code:
B2
Abstract:
An axial displacement judgment device has a first detector acquiring a first detection value from a G sensor which detects an acceleration applied to a radar device, a second detector acquiring a second detection value from a YG sensor which detects the acceleration applied to a vehicle body, and a difference calculator calculating a detection difference value, which is a difference between the first detection value and the second detection value, every first period. The device further has an average difference value calculator calculating an average difference value as an average value of the detection difference values calculated during an acquisition period including the first periods, a deviation calculator calculating a difference standard deviation of the detection difference values calculated during the acquisition period, and a judgment section detecting occurrence of an axial displacement of the radar device based on the average difference value and the difference standard deviation.
