Abstract

An information processing system which includes a center server and a movable body performing a communication with the center server, includes a fuel efficiency information obtainment unit which obtains information on fuel efficiency when the movable body moves in a first direction heading toward the other direction from one direction in a predetermined section and obtains information on fuel efficiency when the movable body moves in a second direction heading toward one direction from the other direction in the section; a comparison unit which compares the fuel efficiency in the first direction with the fuel efficiency in the second direction; and a slope estimation unit which estimates a slope of the section based on a difference between the fuel efficiency in the first direction and the fuel efficiency in the second direction.

Claims

1. An information processing system which includes a center server and a movable body performing a communication with the center server, comprising:

a fuel efficiency information obtainment unit which obtains information on fuel efficiency when the movable body moves in a first direction heading toward the other direction from one direction in a predetermined section and obtains information on fuel efficiency when the movable body moves in a second direction heading toward one direction from the other direction in the section;

a comparison unit which compares the fuel efficiency in the first direction with the fuel efficiency in the second direction; and

a slope estimation unit which estimates a slope of the section based on a difference between the fuel efficiency in the first direction and the fuel efficiency in the second direction.

2. The information processing system according to claim 1, wherein the slope estimation unit estimates that the section is in an uphill slope heading toward the first direction in a case where the fuel efficiency in the second direction is higher than the fuel efficiency in the first direction, and that the section is in a downhill slope heading toward the first direction in a case where the fuel efficiency in the first direction is higher than the fuel efficiency in the second direction.

3. The information processing system according to claim 2, wherein the slope estimation unit estimates that the section is in the uphill slope heading toward the first direction in a case where fuel efficiency dispersion in the second direction is higher than fuel efficiency dispersion in the first direction and the fuel efficiency in the second direction is higher than the fuel efficiency in the first direction, and that the section is in the downhill slope heading toward the first direction in a case where the fuel efficiency dispersion in the first direction is higher than the fuel efficiency dispersion in the second direction and the fuel efficiency in the first direction is higher than the fuel efficiency in the second direction.

4. An information processing device comprising:

a fuel efficiency information obtainment unit which obtains information on fuel efficiency when a movable body moves in a first direction heading toward the other direction from one direction in a predetermined section and obtains information on fuel efficiency when the movable body moves in a second direction heading toward one direction from the other direction in the section;

a comparison unit which compares the fuel efficiency in the first direction with the fuel efficiency in the second direction; and

a slope estimation unit which estimates a slope of the section based on a difference between the fuel efficiency in the first direction and the fuel efficiency in the second direction.
