Abstract

A wear estimation system (10) and method for a tire (12) supporting a vehicle (14) is disclosed. The system (10) comprises a processor being in electronic communication with a CAN bus system of the vehicle and means for determining a total frictional energy of the tire. The processor is configured to: receive the total frictional energy of the tire; divide the total frictional energy into a longitudinal frictional energy estimation and a lateral frictional energy estimation with a separator; receive the longitudinal frictional energy estimation in a longitudinal acceleration classifier; determine at least one of a low, medium, and high longitudinal frictional energy estimate with the longitudinal acceleration classifier; receive the lateral frictional energy estimation in a lateral acceleration classifier; determine at least one of a low, medium, and high lateral frictional energy estimate with the lateral acceleration classifier; generate an output notification including the at least one of the low, medium, and high longitudinal frictional energy estimate and the at least one of the low, medium, and high lateral frictional energy estimate; and determine at least one of an estimated wear rate of the tire and an estimated wear state of the tire from the output notification.
