PROBLEM TO BE SOLVED: To stop a transport vehicle when the transport vehicle contacts a car stop even if there is no sensor for use in contact determination or the sensor fails.SOLUTION: A transport vehicle travel stop control device comprises: a torque-command-value setting unit (502) setting a torque command value for a travel vehicle on the basis of a target velocity and an actual velocity of the transport vehicle; a threshold setting unit (503) setting an upper threshold of the torque command value on the basis of information relating to a state of the transport vehicle; and a travel stop determination unit (504) determining to stop traveling of the transport vehicle, the travel stop determination unit determining to stop traveling of the transport vehicle on condition that the torque command value exceeds the upper limit threshold and the actual velocity of the transport vehicle is zero or close to zero.SELECTED DRAWING: Figure 11
【課題】接触判定に用いられるセンサがないまたは故障した場合でも運搬車両が車止めに接触した際に運搬車両を停止させる。【解決手段】運搬車両の目標速度と実速度と基づき、運搬車両のトルク指令値を設定するトルク指令値設定部(502)と、運搬車両の状態に関する情報に基づき、トルク指令値の上限閾値を設定する閾値設定部(503)と、運搬車両の走行停止を決定する走行停止決定部(504)と、を有し、走行停止決定部は、トルク指令値が前記上限閾値を超え、かつ、運搬車両の実速度がゼロまたはその近傍であることを条件に、運搬車両の走行停止を決定することを特徴とする運搬車両の走行停止制御装置。【選択図】図11
