Abstract
A method of managing clutch thermal loads in a multi-speed dual-clutch transmission (DCT) paired with an engine in a vehicle includes assessing whether the vehicle is being accelerated and ascertaining whether a position of a vehicle accelerator during the acceleration is maintained within a predetermined range. The method also includes identifying a DCT clutch that is being slipped during the acceleration, determining an amount of time remaining until the clutch stops slipping, and comparing a first preset time span indicative of the time remaining until the clutch reaches a threshold temperature with the amount of time remaining until the clutch stops slipping. The method additionally includes setting a time delay for activating an indicator if the amount of time remaining until the clutchs stops slipping is greater than the first preset time span. Furthermore, the method includes activating the indicator after the time delay.
