TIRE INNERLINER-BASED PARAMETER ESTIMATION SYSTEM AND METHOD

摘要

A tire inner liner-based estimation system and method for a vehicle includes a tire pressure sensor mounted to a vehicle tire for detecting a measured tire air cavity pressure; a vehicle speed sensor mounted to provide a measured vehicle speed; a tire identification device mounted to the tire for conveying a tire identification; a tire inner liner deflection sensor mounted to detect and measure a loaded inner liner radius. An estimation of an inner liner-based parameter is iteratively made from the measured tire pressure and the loaded inner liner radius measurement.

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.
