Abstract
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.
