Thermal model for dry dual clutch transmissions

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.
