Abstract
A system for predicting tire lift-off propensity of a vehicle tire includes a vehicle tire-affixed tire-identification device for providing a tire-specific identification, multiple tire-affixed sensors mounted to the tire measuring tire-specific parameters and generating tire-specific parameter information, one or more vehicle-affixed sensor(s) mounted to the vehicle to measure vehicle speed and a lift-off propensity estimator generating a lift-off propensity for the vehicle tire from a database containing experimentally-derived, tire-ID specific, lift-off propensities correlated with measured tire-specific parameter information and vehicle speeds.
Claims20
A lift-off propensity predictive system comprising:
- a vehicle supported by at least one vehicle tire mounted to a hub, the vehicle tire including a tire cavity and a ground-engaging tread, and the tire including a plurality of tire-specific measurable parameters;
- a plurality of tire-affixed sensors mounted to the tire operably measuring the tire-specific parameters and generating tire-specific parameter information;
- a tire-affixed tire-identification device for providing a tire-specific identification;
- at least one vehicle-affixed sensor mounted to the vehicle operably measuring vehicle speed;
- a lift-off propensity estimator operable to generate a lift-off propensity for the one vehicle tire, the lift-off propensity being correlated to a predicted tire contact patch area, wherein the predicted tire contact patch area is calculated from the tire-specific parameter information, the tire-specific identification and the vehicle speed.
A method of making a lift-off propensity estimation comprising:
- mounting at least one vehicle tire to a vehicle, the vehicle tire having a tire cavity and a ground-engaging tread, and the tire having a plurality of tire-specific measurable parameters;
- affixing to the one vehicle tire a tire identification device providing a tire-specific identification;
- affixing at least one vehicle-affixed sensor to the vehicle operably measuring vehicle speed;
- mounting a plurality of tire-affixed sensors to the tire operably measuring the tire-specific parameters to generate tire-specific parameter information;
- inputting the tire-specific parameter information and the tire-specific identification and the vehicle speed into a lift-off propensity estimator;
- calculating a predicted tire contact patch area from the tire-specific parameter information, the tire-specific identification and the vehicle speed with the lift-off propensity estimator;
- and
- correlating the predicted tire contact patch area to a lift-off propensity for the one vehicle tire.
