To achieve a technique that can estimate grounding load on a vehicle with sufficiently high accuracy.SOLUTION: In a grounding load estimation device (100), the wheel angular velocity, stationary load and inertia load of a vehicle are acquired; the stationary load and inertia load are used to compute a first gain with a first gain computing unit (122); a fluctuation of the wheel angular velocity is multiplied by a second gain, to compute a tire effective radius fluctuation with a tire effective radius fluctuation computing unit (121); and the tire effective radius fluctuation is multiplied by the first gain to estimate a road surface load.SELECTED DRAWING: Figure 2
