Abstract

A travel interval division part and a low fuel consumption travel pattern generation part are included, the travel interval division part dividing, based on a reference travel pattern indicating a speed and a travel time period in a case where a vehicle travels without consideration of energy consumption and based on travel route information indicating a travel route that the vehicle travels, the travel route into a plurality of travel intervals at a plurality of reference points, the low fuel consumption travel pattern generation part determining a low fuel consumption travel pattern in which a travel time period of each travel interval falls within a predetermined range of a travel time period of each travel interval of the reference travel pattern and a cumulative speed increase amount in each travel interval is smaller than that of the reference travel pattern.

Claims

1. A travel pattern generation device, comprising:

a travel interval division part dividing, based on a reference travel pattern indicating a speed and a travel time period in a case where a vehicle travels without consideration of energy consumption and based on travel route information indicating a travel route that said vehicle travels, said travel route into a plurality of travel intervals at a plurality of reference points; and

a low fuel consumption travel pattern generation part determining a low fuel consumption travel pattern in which a travel time period of each travel interval falls within a predetermined range of a travel time period of each travel interval of said reference travel pattern and a cumulative speed increase amount in each travel interval is less than that of said reference travel pattern.

2. The travel pattern generation device according to claim 1, further comprising a reference travel pattern generation part generating a reference travel pattern based on travel route information and traffic situation information.

3. The travel pattern generation device according to claim 1, further comprising a reference travel pattern generation part generating a reference travel pattern based on a travel history of a vehicle.

4. The travel pattern generation device according to claim 1, wherein said travel interval division part divides the travel route with a light position of the reference travel pattern, a stop position of a vehicle or a position at which a vehicle is accelerated after being decelerated by a predetermined amount or more serving said reference point.

5. The travel pattern generation device according to claim 1, wherein said travel interval division part divides the travel route using traffic situation information.

6. The travel pattern generation device according to claim 1, wherein said low fuel consumption travel pattern generation part generates the low fuel consumption travel pattern based on average speeds in a processing travel interval, a next interval and a subsequent interval.

7. The travel pattern generation device according to claim 5, wherein said low fuel consumption travel pattern generation part determines, based on a travel phase in a processing target travel interval obtained from an initial speed and an average speed in said processing target interval and a travel phase in a next interval compared with an adjacent interval that is obtained from average speeds of said processing target interval, said next interval and a subsequent interval, a range of an initial speed allowable in said next interval to generate the low fuel consumption travel pattern from the range of the initial speed allowable in said next interval.

8. The travel pattern generation device according to claim 1, wherein said low fuel consumption travel pattern generation part generates the low fuel consumption travel pattern based on average speeds of a processing target interval and a next interval.

9. The travel pattern generation device according to claim 1, wherein said low fuel consumption travel pattern generation part generates the low fuel consumption travel pattern using a speed limit or a minimum speed.
