Road-installed driving supporting device, vehicle-mounted driving supporting device, and driving supporting system
First Claim
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.

Abstract
A vehicle-mounted driving supporting device 2 supports driving on the basis of the presence of a nonpriority vehicle A entering a priority road 50 from a nonpriority road 40. The vehicle-mounted driving supporting device 2 includes an information provision determination device 34 which, when a host vehicle is traveling on the priority road 50, determines whether or not driving support is required on the basis of the specification regarding driving support of the nonpriority vehicle A received from the outside. Therefore, it is possible to avoid a driver from feeling bothered.

-
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, wherein the 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, and the 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. - View Dependent Claims (2)

3. A road-installed driving supporting device having a transceiver which transmits information regarding a nonpriority vehicle entering a priority road from a nonpriority road to a priority vehicle which is traveling on the priority road, the road-installed driving supporting device comprising:
-
a specification determination unit which determines whether the nonpriority vehicle can receive information of driving support from outside based on a detection result output from a vehicle detector and uplink information output from a vehicle which can receive the information of driving support from the outside, and an information processing unit which does not transmit information of the nonpriority vehicle to the priority vehicle if the nonpriority vehicle can receive the information of driving support from the outside, and transmits the information of the nonpriority vehicle to the priority vehicle if the nonpriority vehicle cannot receive the information of driving support from the outside.
