Vehicle display control apparatus and vehicle display control system

1. A vehicle display control apparatus comprising:

a display device arranged at a predetermined position of an own vehicle; and

a control unit configured to cause the display device to display a peripheral screen for presenting a driver of the own vehicle with a position of a different vehicle running around the own vehicle with respect to the own vehicle, wherein

the control unit is configured to

acquire the position of the different vehicle with respect to the own vehicle and a driving manner score as a numerical rating scale representing how good driving manners of the different vehicle are, and

cause the display device to display the driving manner score in such a manner as to correspond to the position of the different vehicle with respect to the own vehicle, on the peripheral screen,

the control unit is configured to acquire the driving manner score based on a history of driving by a driver of the different vehicle, a number of times of a predetermined manner behavior of the different vehicle, and a number of times of a predetermined appreciative action for the different vehicle by a third person, and

the history of driving by the driver of the different vehicle includes a driving frequency, a traffic accident history, and a traffic violation history.

2. The vehicle display control apparatus according to claim 1 , wherein

the control unit is configured to

store the driving manner score in association with absolute positions of a plurality of vehicles,

transmit a request for acquisition including a current absolute position of the own vehicle to an administrative server that is connected to the vehicle display control apparatus via a network in such a manner as to enable exchange of data,

receive an absolute position of the different vehicle that is a vehicle located within a predetermined range of the current absolute position of the own vehicle and the driving manner score of the different vehicle from the administrative server, as a response to the request for acquisition, and

acquire the position of the different vehicle with respect to the own vehicle, based on the current absolute position of the own vehicle and the absolute position of the different vehicle.

3. The vehicle display control apparatus according to claim 1 , wherein

the control unit is configured to

be able to exchange data with the different vehicle through vehicle-to-vehicle communication in response to a distance between the different vehicle and the own vehicle being shorter than a predetermined distance,

receive a current absolute position of the different vehicle and the driving manner score of the different vehicle from the different vehicle via the vehicle-to-vehicle communication, and

acquire the position of the different vehicle with respect to the own vehicle based on a current absolute position of the own vehicle and the current absolute position of the different vehicle.

4. The vehicle display control apparatus according to claim 1 , wherein

the control unit is configured to cause the display device to

display the driving manner score on the peripheral screen in response to the driving manner score of the different vehicle being equal to or larger than a predetermined threshold, and

refrain from displaying the driving manner score on the peripheral screen in response to the driving manner score of the different vehicle being smaller than the threshold.

5. The vehicle display control apparatus according to claim 1 , wherein

the control unit is configured to cause the display device to display the driving manner score of the different vehicle made to correspond to the position of the different vehicle with respect to the own vehicle, by displaying a color corresponding to the driving manner score of the different vehicle located in each of a plurality of divisional regions obtained by dividing a region around the own vehicle for each of the divisional regions on the peripheral screen.

6. A vehicle display control system comprising:

a first vehicle; and

an administrative server connected to the first vehicle via a network in such a manner as to enable exchange of data, wherein

the administrative server is configured to

store absolute positions of a plurality of second vehicles and driving manner scores as numerical rating scales representing how good driving manners of the second vehicles are, in association with each other respectively, and

transmit an absolute position of at least a different vehicle that is one of the second vehicles located around a current absolute position of the first vehicle and the driving manner score of the different vehicle, to the first vehicle, as a response to a request for acquisition including the current absolute position of the first vehicle, upon receiving the request for acquisition from the first vehicle, and

the first vehicle is configured to

acquire a position of the different vehicle with respect to the first vehicle based on the current absolute position of the first vehicle and the absolute positions of the second vehicles, upon receiving the absolute positions of the second vehicles and the driving manner scores of the second vehicles, and

display the driving manner scores of the second vehicles in such a manner as to correspond to the positions of the second vehicles with respect to the first vehicle, on a peripheral screen that is displayed by a display device of the first vehicle to present a driver of the first vehicle with the positions of the second vehicles with respect to the first vehicle,

the driving manner score of each of the second vehicles is determined based on a history of driving by a driver of said each second vehicle, a number of times of a predetermined manner behavior of said each second vehicle, and a number of times of a predetermined appreciative action for said each second vehicle by a third person, and

the history of driving by the driver of said each second vehicle includes a driving frequency, a traffic accident history, and a traffic violation history.

7. The vehicle display control apparatus according to claim 1 , wherein

the driving manner score is defined as a first driving manner score, and

the control unit is configured to acquire a second driving manner score based on a manner distance counter.

8. The vehicle display control apparatus according to claim 7 , wherein

the control unit is configured to determine a value of the manner distance counter by determining whether or not a vehicle-to-vehicle distance between the own vehicle and the different vehicle has remained equal to or longer than a manner distance maintaining state for a predetermined time.

9. The vehicle display control apparatus according to claim 7 , wherein

the control unit is configured to acquire the second driving manner score further based on a manner stop counter.

10. The vehicle display control apparatus according to claim 9 , wherein

the control unit is configured to determine a value of the manner stop counter by determining whether or not there is a time point when an amount of increase in a brake pedal operation amount per unit time in the different vehicle is equal to or larger than a predetermined amount.
