Abstract
A road surface gradient estimation device includes an acquisition unit that acquires each of detection results of an acceleration detection unit that detects an acceleration in a front-rear direction of a vehicle, and a wheel speed detection unit, and acquires information regarding power for driving the vehicle, a derivation unit that derives a gradient of a road surface on which the vehicle is traveling as a first road surface gradient based on the acquired acceleration and wheel speed, and a correction unit that corrects the derived first road surface gradient based on the information regarding the power for driving the vehicle to derive a second road surface gradient.
Claims5
