1. A vehicle interference prevention system for preventing a mutual interference of on-coming vehicles when a plurality of vehicles traveling on-coming to each other on a traveling path with a predetermined road width, characterized in that:

  • each one of the plurality of vehicles is provided with obstacle detection means for detecting an obstacle in front of the vehicle in a traveling direction by transmitting electromagnetic waves with directivity forward in the vehicle traveling direction and receiving reflected electromagnetic waves;

    each one of the plurality of vehicles is provided with transmission/reception means for transmitting/receiving data on own vehicle to/from other vehicle between the plurality of vehicles via a communication system which enables wireless communication over distances between the plurality of vehicles, so as to transmit/receive information on a spot where the vehicles travel on-coming to each other between the vehicles by the transmission/reception means; and

    each one of the plurality of vehicles is provided with velocity control means, if a vehicle detects other vehicle by its obstacle detection means when the vehicles are traveling on-coming to each other for starting deceleration for stopping the own vehicle and for transmitting a deceleration control command for stopping the other vehicle to the other vehicle via the transmission/reception means, and if one of the vehicles did not detect the other vehicle by its obstacle detection means and did not receive the deceleration control command from the other vehicle, for allowing the own vehicle to travel without stopping when the vehicles are traveling on-coming to each other.
