at least one ambient air temperature sensor disposed on the vehicle operative to measure an ambient air temperature, the ambient air temperature being a second steady state input;
at least one vehicle-based sensor providing vehicle-based transient behavior measurements, the transient behavior measurements being used in the generation of transient behavior vehicle-based inputs;
an algorithmic prediction model correlating inner liner tire temperature to the temperature of the tire radially outward surface for the combination represented by the identified tire and the identified vehicle, the algorithmic prediction model operatively receiving the steady-state inputs and the transient behavior vehicle-based inputs and generating based upon the steady-state inputs and the transient behavior inputs a real-time estimation of the temperature of the radially outward surface of the vehicle tire during vehicle operation; and

Abstract
A tire-based system and method for estimating a radially outward tire surface temperature of an identified tire supporting an identified vehicle includes a temperature sensor to measure a tire inner liner temperature. An algorithmic prediction model is empirically trained to correlate inner liner tire temperature to tire radially outward surface temperature for the tire/vehicle combination. The empirically trained algorithmic prediction model receives a steady state temperature-based model inputs including the tire inner liner temperature and an ambient temperature measurement and transient behavior vehicle-based inputs. Based upon the steady state inputs and the transient behavior inputs, a radially outward tire surface temperature estimation is made.
