| description | The present invention inhibits false recognition of a non-vehicle as a vehicle. The present invention is provided with: a vehicle body 1a which travels on wheels; an outside environment recognition device 2 which detects an obstacle in front of the vehicle body 1a; and an obstacle discrimination device 5 which classifies a candidate obstacle detected by the outside environment recognition device 2, into an obstacle and a non-obstacle, and outputs, as the obstacle, the candidate obstacle classified into the obstacle. The obstacle discrimination device 5 comprises: a travel state determination unit 51 which determines whether the candidate obstacle is a moving object or a stationary object; a distance filtering unit 52 which compares the distance of the stationary object initially detected with a distance threshold value; and a reflection intensity filtering unit 53 which calculates statistical information based on reflection intensity information of the obstacle and classifies the candidate obstacle on the basis of the result of comparison with the threshold value. |
