Abstract
Systems and methods are disclosed herein for estimating at least one force acting upon a vehicle-mounted tire. An acceleration waveform () of the tire is detected in a tire radial direction from sampled outputs of a tire-mounted acceleration sensor (). The acceleration waveform is integrated in the tire radial direction to generate a velocity waveform (step). A number of samples during ground contact are calculated from at least first and second peaks in the velocity waveform, wherein a ground contact length is calculated based on at least the calculated number of samples during ground contact, a sampling rate of the outputs of the tire-mounted acceleration sensor, and a velocity of the vehicle. At least one force acting on the tire is estimated from at least the calculated ground contact length (), and an output signal is generated corresponding to the estimated at least one force acting on the tire.
