Claim 9:
10. A system for determining a tire tread wear estimation of a tire, comprising:
at least one sensor configured to generate sensor data indicative of a vehicle velocity, a yaw rate, a steering angle, a wheel speed, a tire pressure, and a tire temperature; and
a controller including a memory configured to store executable instructions, and a microprocessor, in communication with the memory, configured to execute the stored executable instructions, the controller configured to
receive a direct tire tread wear measurement;
perform an indirect tire tread wear estimation based on the sensor data generated;
perform a data fusion of the indirect tire tread wear estimation with the direct tire tread wear measurement, wherein the data fusion is one of the executable instructions;
estimate a percentage tire life remaining and a mileage to end of tire life based on the data fusion;
estimate a refined tire tread wear calibration coefficient for performing future indirect tire tread wear estimations; and
generate, 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 the operator of an unavailability of the tire tread wear estimation and an instruction to the operator to perform the direct tire tread wear measurement.
