Abstract
A wheel attitude control method of the invention comprises the steps of: chronologically obtaining acceleration data in a radial direction of a tire at a center position of a tire tread and at an off-center position spaced apart from the center position toward a shoulder; obtaining respective contact lengths at the center position and the off-center position from the acceleration data; and controlling a wheel attitude, which varies in accordance with changes in a load applied to the wheel when the braking force is imparted to the wheel, based on the obtained contact length at the center position and the obtained contact length at the off-center position.
