Abstract
A method of managing clutch thermal loads in a multi-speed dual-clutch transmission (DCT) that is paired with an internal combustion engine in a vehicle is provided. The method includes assessing operation of the DCT and ascertaining a mode of operation of a clutch in the DCT. The method also includes predicting, in response to the ascertained mode of operation of the clutch, an amount of time remaining until the clutch reaches a threshold temperature. The method additionally includes ascertaining whether the predicted amount of time remaining until the clutch reaches the threshold temperature is within a predetermined range of time. Furthermore, the method includes activating an indicator configured to signal that the predicted amount of time remaining is within the predetermined range of time. A vehicle having a DCT, an internal combustion engine, and a controller configured to predict thermal loading on a clutch in the DCT is also disclosed.
