Abstract: A counter-deflection load estimation system for a tire is provided. The tire includes a pair of sidewalls extending to a circumferential tread and supporting a vehicle, and the vehicle includes a controlled area network bus. In the system, a sensor is mounted to the tire and measures a parameter of the tire. A counter-deflection of the tire is determined from the measured parameter, and a linear vehicle speed signal is received through the controlled area network bus. A processor is in electronic communication with the sensor and with the controlled area network bus. A load estimation module is in electronic communication with the processor, receives the linear vehicle speed signal and the counter-deflection of the tire, and determines a load on the tire.

Abstract: The invention provides a tire inflation pressure method and system. A tire inflation pressure adjustment signal is generated in order to maintain the centerline length of the tire's footprint within a range that allows the good performance of the tire. In embodiments of the invention, a linear relationship between tire inflation pressure, footprint centerline length and vehicle load are exploited to allow for an efficient implementation.
