PROBLEM TO BE SOLVED: To always and accurately estimate the attitude of a mine machine without stopping the operation of it, using two position estimating means.SOLUTION: The dump truck includes: a plurality of rear wheels 15 rotatably attached on a frame 11; and two GPS receivers 101 and 102 arranged so that they are shifted from each other in the longitudinal direction of the vehicle. In a vehicle coordinate system B set in the dump truck, a point optionally selected from a part C in which the plurality of rear wheels are in contact with the ground surface is set as a reference point D. The two GPS receivers are arranged so that a perpendicular is drawn, to the reference point D, from the segment PQ interconnecting two points P and Q whose positions are calculated by the two GPS receivers. |
