Abstract

An evaluation indication systems, methods, and programs display a current location of a vehicle and a map around the current location on a display unit, acquire, as a current efficiency evaluation, a result of comparison between a driving efficiency of a unit section in current travel of the vehicle and a target, and acquire, as a previous efficiency evaluation, a result of comparison between a driving efficiency of the unit section in previous travel previous to the current travel and a target. The systems, methods and programs indicate the current efficiency evaluation and previous efficiency evaluation together on the map and, when the current efficiency evaluation is improved as compared with the previous efficiency evaluation, correct the target to a higher target.

Claims

1. An evaluation indication system comprising:

a map display control unit that displays a current location of a vehicle and a map around the current location on a display unit;

a current efficiency evaluation acquisition unit that acquires, as a current efficiency evaluation, a result of comparison between a driving efficiency of a unit section in current travel of the vehicle and a target; and

a previous efficiency evaluation acquisition unit that acquires, as a previous efficiency evaluation, a result of comparison between a driving efficiency of the unit section in previous travel previous to the current travel and a target, wherein;

the map display control unit indicates the current efficiency evaluation and previous efficiency evaluation together on the map; and

when the current efficiency evaluation is improved as compared with the previous efficiency evaluation, the current efficiency evaluation acquisition unit corrects the target to a higher target.

2. The evaluation indication system according to claim 1, wherein the current efficiency evaluation acquisition unit sets the corrected target as the target in next travel of the vehicle.

3. The evaluation indication system according to claim 1, wherein, when the current efficiency evaluation is improved as compared with the previous efficiency evaluation, the current efficiency evaluation acquisition unit corrects the target such that the target becomes a higher target as a degree of improvement, to which the current efficiency evaluation is improved with respect to the previous efficiency evaluation, increases.

4. The evaluation indication system according to claim 3, wherein, the current efficiency evaluation acquisition unit determines that the degree of improvement is larger as the number of the unit sections in which the target is not achieved in the previous travel and the target is achieved in the current travel increases.

5. The evaluation indication system according to claim 3, wherein the current efficiency evaluation acquisition unit acquires a degree of deviation, to which the driving efficiency deviates from the target in the previous travel, in the unit section in which the target is not achieved in the previous travel and the target is achieved in the current travel, and determines that the degree of improvement is larger as the degree of deviation increases.

6. The evaluation indication system according to claim 3, wherein the current efficiency evaluation acquisition unit acquires a degree of difficulty in improving the driving efficiency in the unit section in which the target is not achieved in the previous travel and the target is achieved in the current travel, and determines that the degree of improvement is larger as the degree of difficulty increases.

7. The evaluation indication system according to claim 3, wherein the current efficiency evaluation acquisition unit acquires a variation in degree of achievement, obtained by subtracting a degree of achievement of the target in the previous travel from a degree of achievement of the target in the current travel, and determines that the degree of improvement is larger as the variation in degree of achievement increases.

8. The evaluation indication system according to claim 7, wherein the current efficiency evaluation acquisition unit acquires the variation in degree of achievement for the unit section in which the target is not achieved in the previous travel.

9. The evaluation indication system according to claim 1, wherein when the current efficiency evaluation is deteriorated as compared with the previous efficiency evaluation, the current efficiency evaluation acquisition unit corrects the target to a lower target.

10. An evaluation indication method comprising:

displaying a current location of a vehicle and a map around the current location on a display unit;

acquiring, as a current efficiency evaluation, a result of comparison between a driving efficiency of a unit section in current travel of the vehicle and a target;

acquiring, a target as a previous efficiency evaluation, a result of comparison between a driving efficiency of the unit section in previous travel previous to the current travel;

indicating the current efficiency evaluation and previous efficiency evaluation together on the map; and

when the current efficiency evaluation is improved as compared with the previous efficiency evaluation, correcting the target to a higher target.

11. A non-transitory computer-readable storage medium that stores computer-executable instructions for performing an evaluation indication function comprising:

displaying a current location of a vehicle and a map around the current location on a display unit;

acquiring, as a current efficiency evaluation, a result of comparison between a driving efficiency of a unit section in current travel of the vehicle and a target;

acquiring, as a previous efficiency evaluation, a result of comparison between a driving efficiency of the unit section in previous travel previous to the current travel and a target;

indicating the current efficiency evaluation and previous efficiency evaluation together on the map; and

when the current efficiency evaluation is improved as compared with the previous efficiency evaluation, correcting the target to a higher target.
