Abstract
A method for estimating wear of a polymer drive belt of a continuously variable transmission (CVT) provided in a vehicle is disclosed. The method comprises: determining a first belt wear-affecting factor based on at least one first operating parameter of the vehicle; determining a second belt wear-affecting factor based on at least one second operating parameter of the vehicle; applying the first and second wear-affecting factors to a belt wear-representative parameter to obtain an adjusted belt wear-representative parameter; and adjusting a total belt wear-representative parameter based on the adjusted belt wear-representative parameter to obtain an updated total belt wear-representative parameter. A vehicle having an electronic control unit configured to perform the method is also disclosed.
