A road section where the host vehicle is currently located is identified and the work rate of a transmission shaft (50), which transmits a driving force from a drive source (47,48) of a host vehicle to a wheel, is derived based on a rotational speed and the torque transmitted by the transmission shaft (50). The energy required to travel through the road section (S x ) is linked to the road section (S x ) and accumulated based on the work rate derived while the host vehicle travels through the road section (S x ). |
