A hauling vehicle includes a storage device that stores map information including a route gradient and a route limiting speed, and a vehicle controller that generates a target speed on the basis of the position, the orientation, and the travelling speed of a vehicle body and the map information. The vehicle controller calculates a protection limiting speed that increases according to the elapse of time starting from detection of actuation of a mechanical brake device, on the basis of the travelling speed and the route gradient. The vehicle controller calculates a first distance across which the vehicle body can travel in the case where the route limiting speed is set as the upper limit value of the target speed after the elapse of a maintenance time settled in advance, and calculates a second distance across which the vehicle body can travel in the case where the protection limiting speed is set as the upper limit value of the target speed. The vehicle controller employs the lower speed from either of the protection limiting speed and the route limiting speed as the upper limit value of the target speed when the first distance is shorter than the second distance, and outputs a maintenance request instruction when the first distance is longer than the second distance.
