PROBLEM TO BE SOLVED: To provide a transportation vehicle capable of detecting a vehicle speed with increased accuracy even when an inclination in an axle direction is varied because of variation of a loaded state.SOLUTION: A transportation vehicle comprises: a vehicle speed sensor 6 that detects a ground speed of movement using a Doppler effect of electromagnetic waves; loaded state information acquisition parts (pressure sensors 15) that acquire loaded state information showing a loaded state with a cargo of the transportation vehicle; a correction angle determination part that determines a correction angle for offsetting a displacement of a pitching angle of axles of the transportation vehicle caused by variation of the loaded state on the basis of the loaded state information; and a movement speed correction part that corrects the speed of movement obtained by the vehicle speed sensor 6 by using the correction angle.SELECTED DRAWING: Figure 3 |
