摘要
A tire-based system and method for estimating longitudinal stiffness between a tire and a road surface includes a longitudinal stiffness adaptation model for calculating longitudinal stiffness between a tire and a road surface from a plurality of scaling factors including the load level, the measured air cavity pressure of the one tire, and the measured temperature of the one tire compensated by a wear state estimation of the one tire. The wear state is obtained from a vehicle-measured vertical mode shift of the tire.
