Abstract:
1. A method for determining interface temperatures for a dry dual clutch mechanism, comprising: determining with a controller that a slipping event is occurring at a friction interface of a clutch in the dry dual clutch mechanism, wherein the dry dual clutch mechanism is not bathed in oil or fluid; determining, with the controller, a heat flux generated by the slipping event of the clutch; determining, with the controller, a flux bulk temperature from the determined heat flux, wherein the flux bulk temperature is the average temperature of a plurality of grid points across the clutch; determining, with the controller, a flux interface temperature from the determined heat flux, wherein the flux interface temperature is the temperature at the friction interface; subtracting, with the controller, the flux interface temperature from the flux bulk temperature to calculate a delta interface temperature; and executing, with the controller, a control action using the calculated delta interface temperature, wherein the control action includes one of storing the delta interface temperature in a storage medium and varying a torque input to the clutch.
