Abstract

Section acquisition systems, methods, and programs acquire a scheduled travel route of a vehicle driven by at least one of an internal combustion engine or a motor. The systems, methods, and programs divide the scheduled travel route that is in a range of a predetermined distance from a current location into a plurality of sections such that a difference in traffic congestion degree is distinguished, and divide the scheduled travel route that is not in the range of the predetermined distance from the current location into a plurality of sections such that a difference in travel load is distinguished.

Claims

1. A section acquisition system, comprising:

a memory storing a computer-executable section acquisition program; and

a processor that is configured by the stored program to;

acquire a scheduled travel route of a vehicle driven by at least one of an internal combustion engine or a motor;

divide the scheduled travel route that is in a range of a predetermined distance from a current location into a plurality of sections such that a difference in traffic congestion degree is distinguished; and

divide the scheduled travel route that is not in the range of the predetermined distance from the current location into a plurality of sections such that a difference in travel load is distinguished.

2. The section acquisition system according to claim 1, wherein the processor is configured by the store program to:

acquire initial sections obtained by dividing the scheduled travel route that is in the range of the predetermined distance from the current location in accordance with a predefined rule; and

if the difference in traffic congestion degree between adjacent ones of the initial sections is less than or equal to a reference value, integrate the adjacent initial sections together to be used as a section after the division.

3. The section acquisition system according to claim 1, wherein the processor is configured by the stored program to:

acquire initial sections obtained by dividing the scheduled travel route that is not in the range of the predetermined distance from the current location in accordance with a predefined rule; and

if the difference in travel load between adjacent ones of the initial sections is less than or equal to a threshold value, integrate the adjacent initial sections together to be used as a section after the division.

4. The section acquisition system according to claim 1, wherein:

the predetermined distance is a distance necessary for matching an SOC of a secondary battery with a target SOC.

5. The section acquisition system according to claim 1, wherein:

the predetermined distance is a predetermined fixed distance.

6. A section acquisition system, comprising:

a memory storing a computer-executable section acquisition program; and

a processor that is configured by the stored program to;

acquire a scheduled travel route of a vehicle driven by at least one of an internal combustion engine or a motor; and

divide the scheduled travel route into a plurality of sections in such a manner that the number of sections per unit distance is larger in the scheduled travel route that is in a range of a predetermined distance from a current location than in the scheduled travel route that is not in the range of the predetermined distance from the current location.

7. A section acquisition method, comprising:

acquiring a scheduled travel route of a vehicle driven by at least one of an internal combustion engine or a motor;

dividing the scheduled travel route that is in a range of a predetermined distance from a current location into a plurality of sections such that a difference in traffic congestion degree is distinguished; and

dividing the scheduled travel route that is not in the range of the predetermined distance from the current location into a plurality of sections such that a difference in travel load is distinguished.

8. A computer-readable storage medium storing a computer-executable section acquisition program, the program comprising:

instructions for acquiring a scheduled travel route of a vehicle driven by at least one of an internal combustion engine or a motor;

instructions for dividing the scheduled travel route that is in a range of a predetermined distance from a current location into a plurality of sections such that a difference in traffic congestion degree is distinguished; and

instructions for dividing the scheduled travel route that is not in the range of the predetermined distance from the current location into a plurality of sections such that a difference in travel load is distinguished.
