Claim:
1. A transport vehicle including a plurality of wheels, comprising: a plurality of body sensors that detect a state of the transport vehicle; a traveling drive device; a traveling stop control device that controls the traveling drive device based on information regarding the state of the transport vehicle detected by the body sensors, wherein the traveling stop control device includes: a torque command value setting module that sets a torque command value for the traveling drive device based on a target speed of the transport vehicle and an actual speed of the transport vehicle which is calculated using a rotational speed of the wheels of the transport vehicle detected by a vehicle speed sensor as one of the plurality of body sensors; a threshold value setting module that sets an upper limit threshold value for the torque command value based on the information regarding the state of the transport vehicle detected by the body sensors; a traveling stop determination module that determines a traveling stop of the transport vehicle, wherein the traveling stop determination module outputs the determination of the traveling stop of the transport vehicle to the traveling drive device when the torque command value exceeds an upper limit threshold value and the actual speed of the transport vehicle is less than or equal to a predetermined threshold value, and wherein, when the traveling drive device receives the determination, the traveling drive device brakes the transport vehicle.
