Abstract

A tire wear state estimation system and method is disclosed. The system comprises at least one tire supporting a vehicle; a CAN bus system disposed on the vehicle; and at least one sensor disposed on the vehicle and in electronic communication with the CAN bus system. The at least one sensor is operative to measure selected parameters associated with the vehicle and to communicate data for the selected parameters through the CAN bus system, including a first set of data, a second set of data and a third set of data. The system further comprises a rolling radius estimator operative to receive the first set of data and estimate a rolling radius for the at least one tire; an acceleration slip estimator operative to receive the second set of data and the estimated rolling radius to estimate the slip of the at least one tire during acceleration of the vehicle; a braking slip estimator operative to receive the third set of data and the estimated rolling radius to estimate the slip of the at least one tire during braking of the vehicle; and a tire slip analyzer to correlate the estimation of the slip of the at least one tire during acceleration of the vehicle and the slip of the at least one tire during braking of the vehicle and generate an estimated wear state of the at least one tire.
