Claim 0:
1. A method for determining a tire tread wear estimation of a tire, comprising:
receiving, by a controller, sensor data from one or more vehicle sensors in communication with the controller, wherein the controller includes a memory configured to store executable instructions to be used by the controller, and a microprocessor in communication with the memory to execute the stored executable instructions;
receiving, by the controller, vehicle dynamics data from one or more vehicle systems in communication with the controller;
receiving, by the controller, a direct tire tread wear measurement;
performing, by the controller, an indirect tire tread wear estimation using the sensor data and the vehicle dynamics data received by the controller;
performing, by the controller, a data fusion of the indirect tire tread wear estimation with the direct tire tread wear measurement received by the controller, wherein the data fusion is one of the executable instructions;
estimating, by the controller, a percentage tire life remaining and a mileage to end of tire life based on the data fusion performed by the controller;
estimating, by the controller, a refined tire tread wear calibration coefficient for performing future indirect tire tread wear estimations; and
generating, by the controller, based on an estimated error in a tire tread wear distribution, one of a first notification to an operator of the percentage tire life remaining and mileage to end of tire life and a second notification to an operator of an unavailability of the tire tread wear estimation and an instruction to the operator to perform the direct tire tread wear measurement.
