ABSTRACT:
A method is for controlling a rate of flow of cooling oil to a friction launch clutch and electric motor in a hybrid electric vehicle powertrain. The rate of flow is determined by changes in clutch temperature and motor temperature. Cooling oil flow in excess of the flow required to maintain a desired temperature is avoided.
