Abstract:
A method for controlling an impeller clutch of a torque converter includes determining a function relating a K-factor of the torque, determining a current engine torque, determining a desired impeller clutch slip, using the function determine the actual impeller speed and thus actual clutch slip, and adjusting the operating state of the impeller clutch to produce the desired impeller clutch slip.
