Abstract:
1. A computer-implemented method of calculating a magnitude of a cornering force applied to each of a plurality of wheels of a vehicle when the vehicle is cornering, each of the plurality of wheels comprising a tire, and being implemented by a computer programmed to carry out the method steps, the method comprising: measuring, with an electronic device, a magnitude of a centrifugal force applied to the vehicle when the vehicle is cornering, the centrifugal force being in a direction substantially orthogonal to a vehicle traveling direction; determining, with a computer, a contact length in a wheel circumferential direction, at a contact portion of each of the plurality of wheels when the vehicle is cornering; determining, with the computer, an amount of deformation in a wheel width direction when the vehicle is cornering, at the contact portion of each of the plurality of wheels; and calculating, with the computer, a magnitude of a cornering force applied to each of the plurality of wheels, based on the magnitude of the centrifugal force measured with the electronics device, the contact length, and the amount of the deformation in the wheel width direction when the vehicle is cornering.
