Abstract

A method for extracting changes in characteristics of a tire supporting a vehicle is provided. The method includes extracting selected tire characteristics from at least one sensor mounted on the tire. The selected tire characteristics are transmitted to a remote processor and are stored in a historical data log that is in communication with the remote processor. At least one tire characteristic of interest is selected, and a time series decomposition model is applied to data from the historical data log to delineate exogenous inputs from an underlying trend in the selected tire characteristic of interest. A learning model is applied to the underlying trend in the selected tire characteristic of interest to model a relationship between the selected tire characteristic of interest and a condition of the tire. A prediction value for a condition of the tire is output from the learning model.

First claim

What is claimed is:

1 . A method for extracting changes in characteristics of a tire supporting a vehicle, the method comprising the steps of:
extracting selected tire characteristics from at least one sensor mounted on the tire; transmitting the selected tire characteristics to a remote processor; storing the selected tire characteristics in a historical data log in communication with the remote processor; selecting at least one tire characteristic of interest; applying a time series decomposition model to data from the historical data log to delineate exogenous inputs from an underlying trend in the selected tire characteristic of interest; applying a learning model to the underlying trend in the selected tire characteristic of interest to model a relationship between the selected tire characteristic of interest and a condition of the tire; and outputting from the learning model a prediction value for a condition of the tire.

2 . The method for extracting changes in characteristics of a tire supporting a vehicle of claim 1 , wherein the step of extracting tire characteristics from at least one sensor mounted on the tire includes the steps of:
mounting a processor on at least one of the vehicle and the tire; receiving tire characteristics from a sensor unit mounted on the tire in the processor that is mounted on at least one of the vehicle and the tire; and executing on the processor that is mounted on at least one of the vehicle and the tire a data analysis tool to retrieve the selected characteristics.

3 . The method for extracting changes in characteristics of a tire supporting a vehicle of claim 1 , further comprising the step of extracting selected tire characteristics from sensors mounted on the vehicle.

4 . The method for extracting changes in characteristics of a tire supporting a vehicle of claim 1 , further comprising the step of extracting selected tire characteristics from a vehicle CAN bus.

5 . The method for extracting changes in characteristics of a tire supporting a vehicle of claim 1 , further comprising the step of augmenting the historical data log with contextual information including at least one of weather, road roughness, and road topology data.

6 . The method for extracting changes in characteristics of a tire supporting a vehicle of claim 1 , wherein the deep learning model includes at least one of a machine learning model, a deep learning model, and a statistical model.

7 . The method for extracting changes in characteristics of a tire supporting a vehicle of claim 1 , wherein the condition of the tire includes at least one of a wear state of the tire and a load of the tire.

8 . The method for extracting changes in characteristics of a tire supporting a vehicle of claim 1 , further comprising the step of transmitting the prediction value to at least one of a service center and a fleet manager.

9 . The method for extracting changes in characteristics of a tire supporting a vehicle of claim 1 , further comprising the step of transmitting the prediction value to a display device that is accessible to a user of the vehicle.

10 . The method for extracting changes in characteristics of a tire supporting a vehicle of claim 1 , further comprising the step of transmitting the prediction value to at least one of an electronic control unit of the vehicle and a vehicle control system.
