1. A vehicle-mounted driving supporting device which supports driving depending on the presence of a nonpriority vehicle entering a priority road from a nonpriority road, the vehicle-mounted driving supporting device comprising:

  • a transceiver that receives and transmits information to and from a road-installed driving supporting device;

    a support determination unit which, when a host vehicle is a priority vehicle which is traveling on the priority road, determines whether or not the nonpriority vehicle is identical to a vehicle which performs communication through vehicle-vehicle communication, based on information which uniquely specifies the nonpriority vehicle received from a transceiver of the road-installed driving supporting device and information which uniquely specifies the vehicle which performs communication through vehicle-vehicle communication, whereinthe support determination unit determines that the nonpriority vehicle can receive information of driving support from outside when the nonpriority vehicle is identical to the vehicle which performs communication through vehicle-vehicle communication,the support determination unit determines that the nonpriority vehicle cannot receive the information of driving support from the outside when the nonpriority vehicle is not identical to the vehicle which performs communication through vehicle-vehicle communication, andthe vehicle-mounted driving supporting device does not execute the driving support for the host vehicle if the nonpriority vehicle can receive the information of driving support from the outside, and the vehicle-mounted driving supporting device executes the driving support for the host vehicle if the nonpriority vehicle cannot receive the information of driving support from the outside.
