Abstract: A method for determining interface temperatures for a dry dual clutch mechanism includes determining that a slipping event is occurring at a friction interface of a clutch in the dry dual clutch mechanism, and determining a heat flux generated by the slipping event. The method includes determining a flux bulk temperature from the determined heat flux and determining a flux interface temperature from the determined heat flux. The flux interface temperature is the temperature at the friction interface during the slipping event. The method calculates a delta interface temperature by subtracting the flux interface temperature from the flux bulk temperature. The method executes a control action with the calculated delta interface temperature.

Abstract: A torque transmitting system includes a case, first and second clutch plates, and a ramp member that is selectively rotatable about an axis and that defines a ramp surface. The system also includes an electric motor having a motor housing, wherein the case is rotatable relative to the housing about the axis. The motor is configured to selectively apply torque to rotate the ramp member. The system additionally includes a roller element mounted with respect to the case and contacting the ramp surface. The ramp surface is configured such that, when the ramp member is rotated about the axis, the roller element exerts a reaction force on the ramp surface that urges the ramp member to move in a first axial direction and thereby transmit the reaction force to the clutch plates. A transmission assembly including the above described torque transmitting system is also disclosed.

Abstract: A method for responding to a rapid change in engine torque includes monitoring a change in engine torque and determining a rapid change in engine torque when the change in engine torque exceeds a threshold change in engine torque. Subsequent to determining a rapid change in engine torque, an increase in the torque converter slip is provided by reducing the torque converter clutch pressure command by a selected value and thereafter the feedback control is deactivated for a predetermined duration. Subsequent to the predetermined duration, the feedback control is reactivated to decrease the torque converter slip toward a desired torque converter slip value.
