1. A vehicle interference prevention system including an unmanned vehicle comprising vehicle position-measuring means for measuring a position of its own vehicle and traveling over a travel route based on predetermined instruction data, a first manned vehicle having position-measuring means for measuring a position of its own vehicle, and a second manned vehicle traveling over the travel route guided by the first manned vehicle;

  • wherein the unmanned vehicle and the first manned vehicle each comprises communication means for transmitting and receiving predetermined information among themselves;

    the first manned vehicle transmits to the unmanned vehicle via the communication means a mode which is either a guiding mode wherein the second manned vehicle is guided, or a non-guiding mode wherein the second manned vehicle is not guided; and

    transmits to the unmanned vehicle via the communication means position information indicating the vehicle position determined by the position-measuring means; and

    the unmanned vehicle, in the event that the mode received via the communication means is the non-guiding mode, is controlled, on the basis of the position information from the first manned vehicle, in such a way as to avoid entering an area of a given range that includes a current position of the first manned vehicle;

    whereas in the case of the guiding mode, it is controlled, on the basis of the position information from the first manned vehicle, in such a way as to avoid entering the current position of the first manned vehicle and an area of a given range lying to a rear of the first manned vehicle.
