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.

Claims

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 support determination unit which, when a host vehicle is a priority vehicle which is traveling on the priority road, determines whether or not driving support is required on the basis of the specification regarding driving support of the nonpriority vehicle received from the outside.

2. The vehicle-mounted driving supporting device according to claim 1,

wherein the support determination unit determines whether or not the driving support is required on the basis of information regarding a function of receiving outside information of the nonpriority vehicle.

3. The vehicle-mounted driving supporting device according to claim 2,

wherein, when the nonpriority vehicle is configured to perform vehicle-to-vehicle communication, the support determination unit does not execute the driving support.

4. The vehicle-mounted driving supporting device according to claim 2,

wherein, when the nonpriority vehicle can acquire information regarding the priority vehicle from an optical beacon, the support determination unit does not execute the driving support.

5. A road-installed driving supporting device 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 the specification of driving support regarding communication of the nonpriority vehicle, and

an information processing unit which determines whether or not the transmission of information regarding the nonpriority vehicle is required on the basis of the specification of driving support regarding the communication.

6. A driving supporting system which, when a support-target vehicle is traveling on a priority road, supports the driving of the support-target vehicle on the basis of the presence of a nonpriority vehicle entering from a nonpriority road, the driving supporting system comprising:

a vehicle-mounted driving supporting device which is mounted in the support-target vehicle; and

a road-installed driving supporting device which is configured to communicate with the support-target vehicle,

wherein the road-installed driving supporting device includes

a specification determination unit which determines the specification of driving support regarding road-to-vehicle communication of the nonpriority vehicle, and

an information processing unit which determines whether or not processing for transmitting information regarding the nonpriority vehicle to the support-target vehicle is required on the basis of the specification of driving support regarding the road-to-vehicle communication, and

the vehicle-mounted driving supporting device includes

a support determination unit which, when information regarding the nonpriority vehicle is received from the road-installed driving device, determines whether or not driving support is required on the basis of whether or not vehicle-to-vehicle communication between the support-target vehicle and the nonpriority vehicle can be performed.
