Abstract:
A clutch temperature prediction module for a dual clutch transmission (DCT) includes at least one clutch slip power module that determines a first clutch slip power of a first clutch and a second clutch slip power of a second clutch. A temperature calculation module receives the first clutch slip power, the second clutch slip power, an ambient air temperature, an engine oil temperature, and a transmission oil temperature, and calculates at least one clutch plate temperature and a clutch housing temperature based on the first clutch slip power, the second clutch slip power, the ambient air temperature, the engine oil temperature, and the transmission oil temperature using a linear time-invariant (LTI) model.
