Travel energy estimating device, travel energy estimating method, and computer program

A travel energy estimating method, comprising:

• acquiring, by a travel energy estimating device, a route that is composed of a road link on which a target vehicle being an electric vehicle is planned to travel;
• dividing, by the travel energy estimating device, the route into one or more sections, each section including a speed change prediction point at which a change in a travel speed of the target vehicle is expected, each section being composed of one or a plurality of road links;
• acquiring, by the travel energy estimating device, a speed model for each section, the speed model indicating a temporal transition of the travel speed of the target vehicle;
• and
• estimating, by the travel energy estimating device, travel energy of the target vehicle during traveling on the route, based on the speed model acquired for each section.

A computer program that causes a computer to function as:

• a route acquisition unit configured to acquire a route that is composed of a road link on which a target vehicle being an electric vehicle is planned to travel;
• a route division unit configured to divide the route into one or more sections, each section including a speed change prediction point at which a change in a travel speed of the target vehicle is expected, each section being composed of one or a plurality of road links;
• a speed model acquisition unit configured to acquire a speed model for each section, the speed model indicating a temporal transition of the travel speed of the target vehicle;
• and
• a travel energy estimation unit configured to estimate travel energy of the target vehicle during traveling on the route, based on the speed model acquired for each section.
