Abstract
According to one embodiment, a resistance estimation apparatus includes a first detection unit, a second detection unit, a third detection unit and a first calculation unit. The first detection unit detects, as an output value, an output of a driving source of a vehicle. The second detection unit detects, as a braking value, a strength of a braking force. The third detection unit detects a speed of the vehicle. The first calculation unit calculates a traveling resistance resulting from a road surface that the vehicle has traveled during a traveling period, using a vehicle characteristic, the output value, the braking value and the speed, the traveling period including a period from a first time point when the vehicle starts and the speed changes from zero to a second time point when the vehicle stops and the speed changes to zero.
