A road section where the host vehicle is currently located is identified and the work rate of a transmission shaft, which transmits a driving force from a drive source of a host vehicle to a wheel, is derived based on a rotational speed and the torque transmitted by the transmission shaft. The energy required to travel through the road section is linked to the road section and accumulated based on the work rate derived while the host vehicle travels through the road section.

Travel energy learning device, and method

A travel energy learning device includes: 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 indicating work rate of a transmission shaft based on rate of rotation of the transmission shaft and torque transmitted by the transmission shaft; and an energy information accumulating unit that derives required energy information indicating the energy required for traveling the road section based on the derived information that indicates the work rate during travel of the road section, links the derived required energy information to the road section and the travel condition information, and accumulates the required energy information.
