Abstract
A method of clutch wear notification comprises detecting engaged clutch positions at a first interval and storing the values of the engaged clutch positions. The stored values of the engaged clutch positions can be averaged at a second interval to create running averages, and the running averages can be stored. The running averages are compared at a third interval to determine a rate of change in the clutch positions. A clutch wear-out is signaled when comparing the running averages indicates that the rate of change in the clutch positions deviates from a normal rate of change. The clutch position during an engaged condition can deviate from the normal rate of change when the axial position of the release bearing begins to increase due to an adjustment mechanism ceasing to adjust.
