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
【課題】積載状態の変化により車軸方向の傾きが変動した場合にも車速をより正確に検出することができる運搬車両を提供することができる【解決手段】電磁波のドップラ効果を利用して対地移動速度を検出する車速センサ6と、運搬車両の積荷の積載状態を示す積載状態情報を取得する積載状態情報取得部(圧力センサ15)と、積載状態の変動に伴う運搬車両の車軸のピッチング角の変位を相殺するための補正角を、積載状態情報を基に決定する補正角決定部と、車速センサ6より得られる移動速度を、補正角を用いて補正する移動速度補正部と、を備えることを特徴とする。【選択図】図3
