Claim Text:
1. A tire inner liner-based system for estimating a vehicle parameter comprising: at least one tire supporting a vehicle, the tire having tire sidewalls and a tire crown supporting a tire inner liner defining a tire air cavity; at least one tire pressure sensor mounted to the one tire for detecting a measured tire air cavity pressure; at least one vehicle speed sensor mounted to provide a measured vehicle speed; at least one tire identification device mounted to the tire for providing a tire identification; at least one tire inner liner deflection sensor mounted to provide a loaded inner liner radius measurement; estimating means for calculating a vehicle parameter estimation estimated tire parameter from the measured tire air cavity pressure and the loaded inner liner radius measurement; and wherein the at least one tire inner liner deflection sensor is a sensor taken from the sensor group laser distance sensor, eddy current sensor, magneto-inductive sensor, capacitive sensor.
