Title:
TRAVELING DIRECTION STATE DETECTION DEVICE AND TRUCK USING SAME
Document Type and Number:
WIPO Patent Application WO/2021/024838
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a traveling direction state detection device which reliably detects a level difference, an inclination, and an opening of a traveling surface on which a vehicle wheel travels, and a truck using same. The traveling direction state detection device 10 for detecting a level difference, an inclination, and an opening of a traveling surface G on which a vehicle wheel 12 travels is provided with: a long distance sensor 14 which is provided near the front side of the traveling direction X of the vehicle wheel 12 and linearly measures the distance L1 to a first linear location LN1 that is on a traveling surface G diagonally downward in the traveling direction and is vertical to the traveling direction X; a short distance sensor 16 which linearly measures the distance L2 to a second linear location LN2 that is rearward in the traveling direction X from the traveling surface G that is diagonally downward in the traveling direction, is on the traveling surface G ahead of a ground point P of the vehicle wheel 12 in the traveling direction X, and is vertical to the traveling direction X; and a detection unit 18 which detects the level difference, the inclination, and the opening of the traveling surface G on the basis of change amounts in the distances L1, L2 consecutively measured for each constant time by means of the long distance sensor 14 and the short distance sensor 16.
