Patent ID: 8897979

Claim:
A method of determining temperatures for a dry dual clutch mechanism, comprising: determining a first heat input from a first clutch; determining a second heat input from a second clutch, which is separated from the first clutch by a center plate; determining a housing air temperature of housing air within a bell housing case of the dry dual clutch mechanism; applying a thermal model using the determined first heat input and second heat input, wherein the thermal model includes temperature states for the first clutch, the second clutch, and the center plate; determining a first clutch temperature from the thermal model; determining a second clutch temperature from the thermal model; and executing a control action using the determined first clutch temperature and the determined second clutch temperature, wherein the control action includes determining a first coefficient of friction from the determined first clutch temperature and determining a second coefficient of friction from the determined second clutch temperature, and includes selectively transferring torque across one of the first clutch and the second clutch.
