Abstract
An object of the present invention is to provide a vehicle motion state estimation device capable of estimating a vertical momentum of a vehicle with high accuracy from a wheel speed sensor signal during traveling such as acceleration or deceleration, turning, or the like where wheel slips in longitudinal and lateral directions occur. The present invention estimates and removes a variation component caused by a wheel slip from variation components of a wheel speed sensor signal to extract a variation component caused by a displacement of a suspension, and estimates a vertical momentum of a vehicle from the extracted variation component caused by the displacement of the suspension.
