Abstract

There is provided a driving support device includes a communication unit configured to perform communication with another vehicle; a storage unit configured to store reference information including information regarding positional relationship of the another vehicle with respect to an own-vehicle, information regarding a direction of relative displacement of the another vehicle with respect to the own-vehicle, and a control threshold value, each associated with one another; and a control unit configured to perform predetermined safety control based on whether or not information derived from running information on the another vehicle received by the communication unit and running information on the own-vehicle correspond to the reference information stored by the storage unit.

Claims

1. A driving support device comprising:

a communication unit configured to perform communication with another vehicle;

a storage unit configured to store reference information including position information regarding positional relationship of the another vehicle with respect to an own-vehicle, direction information regarding a direction of relative displacement of the another vehicle with respect to the own-vehicle, and a control threshold value, the position information, the direction information and the control threshold being associated with each other; and

a control unit configured to perform predetermined safety control based on whether or not information derived from running information on the another vehicle received by the communication unit and running information on the own-vehicle correspond to the reference information stored by the storage unit.

2. The driving support device according to claim 1,

wherein the reference information is provided for each of classified patterns of encounter situation between the another vehicle and the own-vehicle, and

the control unit performs the predetermined safety control based on the reference information for each pattern of encounter situation.

3. The driving support device according to claim 1,

wherein the position information regarding positional relationship in the reference information includes a range of azimuth of the another vehicle as viewed from the own-vehicle and a range of relative distance between the another vehicle and the own-vehicle, and

the control unit performs the predetermined safety control when an azimuth and a relative distance of the another vehicle each fall within the range of azimuth of the another vehicle and the range of relative distance, the azimuth and relative distance of the another vehicle being derived from the running information on the another vehicle and the running information on the own-vehicle.

4. A vehicle comprising:

the driving support device according to claim 1; and

a collection unit configured to transmit the running information on the own-vehicle to the driving support device.

6. The driving support device according to claim 1, wherein the control unit:

calculates a relative moving direction of the another vehicle, and a relative distance of the another vehicle, with respect to the own vehicle using the running information of the another vehicle and the running information of the own vehicle,

determines whether there is possibility of collision between the another vehicle and the own vehicle by detecting that the another vehicle enters a preset area using the relative distance, and if so;

determines whether the possibility of collision is high or not by evaluating correspondence between the relative moving direction of the another vehicle and the reference information.

7. The driving support device according to claim 6, wherein the preset area extends radially from the own vehicle.

5. A non-transitory computer readable medium storing a control program causing a computer to execute the steps comprising:

performing communication with another vehicle;

storing reference information including position information regarding positional relationship of the another vehicle with respect to a own-vehicle, direction information regarding a direction of relative displacement of the another vehicle with respect to the own-vehicle, and a control threshold value, the position information, the direction information and the control threshold being associated with each other; and

performing predetermined safety control based on whether or not information derived from running information on the another vehicle received in the performing communication and running information on the own-vehicle correspond to the stored reference information.

8. A driving support method comprising:

obtaining running information of another vehicle via communication with the another vehicle using wireless communication device;

obtaining running information of an own vehicle;

calculating, using a computer, a relative moving direction of the another vehicle, and a relative distance of the another vehicle with respect to the own vehicle using the running information of the another vehicle and the running information of the own vehicle;

determining, using the computer, whether or not information derived from the running information of the another vehicle and the running information of the own-vehicle correspond to reference information stored in a storage device to determine whether there is possibility of collision between the another vehicle and the own vehicle; and

performing predetermined safety control when it is determined that there is possibility of collision,

wherein the reference information includes position information regarding positional relationship of the another vehicle with respect to the own vehicle, direction information regarding a direction of relative displacement of the another vehicle with respect to the own vehicle, and a control threshold value, the position information, the direction information and the control threshold being associated with each other.

9. The driving support method according to claim 8 further comprising:

determining whether there is possibility of collision between the another vehicle and the own vehicle by detecting that the another vehicle enters a preset area by using the relative distance, and if so;

determining whether the possibility of collision is high or not by evaluating correspondence between the relative moving direction of the another vehicle and the reference information.

10. The driving support method according to claim 9, wherein the preset area extends radially from the own vehicle.
