ABSTRACT:
A method of calculating a cornering force to be applied to each wheel provided to a vehicle which is cornering, comprising the steps of: obtaining a magnitude of a centrifugal force to the vehicle in a direction substantially orthogonal to a vehicle traveling direction, a contact length of each wheel during the cornering of the vehicle, and an amount of deformation in a wheel width direction at the contact portion of each wheel of the vehicle, calculating a difference between the obtained amount of the deformation and an amount of deformation in the wheel width direction under a straight forward travel condition of the vehicle for each wheel, and calculating a cornering force for each wheel based on the magnitude of the centrifugal force, the contact length, and the difference between amounts of deformation in the wheel width direction.
