Abstract
A method for detecting and mitigating excessive clutch disc wear for a manual transmission includes determining if a clutch pedal position is depressed greater than or equal to a first predetermined pedal position threshold and if the vehicle speed is less than or equal to a predetermined vehicle speed threshold. The method further includes determining if the clutch pedal position is depressed greater than or equal to a second predetermined pedal position threshold when the clutch pedal position is depressed less than the first predetermined pedal position threshold. The method still further includes calculating a clutch disc heat flux value and a clutch disc surface temperature. The method further includes displaying an alert/warning and a remedial action message to a vehicle operator when the clutch disc surface temperature is greater than or equal to a predetermined surface temperature threshold.
