Method for electric power boosting in a powertrain system

摘要

A powertrain system is operative to transfer power between an input member (12) and a plurality of power actuators (56,72) and an output member (64) to generate an output torque. The power actuators (56,72) are connected to an energy storage device (74). A method for controlling the powertrain system includes monitoring operating conditions of the powertrain system, determining an electric power limit for output power of the energy storage device (74), selectively enabling electric power boost based upon the operating conditions of the powertrain system, and increasing the electric power limit when electric power boost is enabled.
