TRAVEL ENERGY LEARNING DEVICE, METHOD, AND PROGRAM
First Claim
1. A travel energy learning device comprising:
- a road section identifying unit that identifies a road section where a host vehicle is currently located;
a travel condition information obtaining unit that obtains travel condition information that indicates a travel condition when the host vehicle traveled the road section;
a work rate deriving unit that derives information that indicates a work rate of a transmission shaft based on a revolution of the transmission shaft that transmits a driving force from a drive source of the host vehicle to a wheel and torque transmitted by the transmission shaft; and
an energy information accumulating unit that derives information that indicates the energy required for traveling the road section based on the derived information that indicates the work rate during traveling of the host vehicle through the road section, links the derived information that indicates the energy required for traveling the road section to the road section and the travel condition information, and accumulates the information that indicates the energy required for traveling the road section.
