摘要： A method and powertrain apparatus for controlling a hybrid electric vehicle powertrain to maintain a catalyst within a catalytic converter at an efficient operating temperature while also maximizing the use of electric vehicle operating mode. The method and apparatus determine, during an electric vehicle operating mode, whether a catalyst efficiency is below a predetermined threshold and, if it is determined that the catalyst efficiency is below the predetermined threshold, suspend the electric vehicle operating mode and turn on the vehicle's engine to bring the catalyst efficiency to or above the predetermined threshold.

摘要： A method for preparing an internal combustion (IC) engine component of a hybrid automotive powertrain for shutdown so as to enable clean restart is disclosed herein. The method includes determining if the IC engine is about to enter a shutdown mode. The method includes determining a number of engine run cycles to fill an intake manifold of the IC engine with clean air, if it is determined the IC engine is about to enter the shutdown mode. The method includes running the IC engine for the determined number of cycles to fill the intake manifold of the IC engine with clean air before shutting the IC engine down.

摘要： A method and apparatus for heating a catalytic converter's catalyst to an efficient operating temperature in a hybrid electric vehicle when the vehicle is in a charge limited mode such as e.g., the charge depleting mode or when the vehicle's high voltage battery is otherwise charge limited. The method and apparatus determine whether a high voltage battery of the vehicle is incapable of accepting a first amount of charge associated with a first procedure to warm-up the catalyst. If it is determined that the high voltage battery is incapable of accepting the first amount of charge, a second procedure with an acceptable amount of charge is performed to warm-up the catalyst.
