Abstract
Provided is a wheel load estimation device configured to acquire wheel speed information of each wheel included in a vehicle from a wheel speed sensor provided in the vehicle; to calculate a front-rear load ratio and a left-right load ratio based on the wheel speed information; and to calculate a wheel load ratio expressing a relative wheel load between the wheels included in the vehicle, with respect to at least one wheel of the vehicle, based on the front-rear load ratio and the left-right load ratio. The front-rear load ratio is a ratio between a load applied to a front wheel of the vehicle and a load applied to a rear wheel of the vehicle, and the left-right load ratio is a ratio between a load applied to a left wheel of the vehicle and a load applied to a right wheel of the vehicle.
