Abstract
The present invention prevents the interference of vehicles traveling on-coming to each other when a plurality of vehicles are traveling on-coming to each other on a traveling path with a predetermined road width without increase in cost caused by setting a wide course width and without a drop in work efficiency caused by decreasing velocity. If one of the vehicles detects the other vehicle by its obstacle detection means when the vehicles are traveling on-coming to each other, the vehicle which detects the other vehicle begins deceleration to stop itself. At the same time, this vehicle transmits a deceleration control command for stopping the other vehicle to the other vehicle via transmission/reception means, therefore the other vehicle starts deceleration even if this vehicle cannot detect an obstacle. The present invention is also applied when unmanned vehicles using autonomously guidance traveling based on the course data and traveling position data or an unmanned vehicle and a manned vehicle pass each other on the going and coming paths immediately adjacent to each other, where each vehicle has communication means for transmitting traveling position data of the respective vehicle and receiving traveling position data of the other vehicle, an unmanned vehicle has approach detection means for detecting the approach of the other vehicle based on its own traveling position data and position data of the other vehicle, and traveling control means for shifting its own vehicle toward the road shoulder side at detection of an approach.
