A wheel load of each wheel or a vehicle body load is estimated based on a gain of a resonance frequency of a tire, and the estimated wheel load or vehicle body load is applied to a braking control or an acceleration control. Further, a ground contact load of each wheel or the vehicle body load of the vehicle is estimated based on the gain of the resonance frequency extracted from each of the tires for use in a vehicle control.
