Method for controlling a powertrain system based upon torque machine temperature

A powertrain system includes an engine (14) coupled to an input member (12) of a transmission device (10) operative to transmit torque between the input member (12) and a torque machine (56,72) and an output member (64). The torque machine (56,72) is connected to an energy storage device (74). A met...

More Information
Summary:A powertrain system includes an engine (14) coupled to an input member (12) of a transmission device (10) operative to transmit torque between the input member (12) and a torque machine (56,72) and an output member (64). The torque machine (56,72) is connected to an energy storage device (74). A method for controlling the powertrain system include monitoring a temperature of the torque machine (56,72), selecting a candidate powertrain system operating point, determining an electrical power input and a motor power output of the torque machine (56,72) for the candidate powertrain system operating point, determining a power loss for the torque machine (56,72) associated with the motor power output of the torque machine (56,72) and the electrical power input, and determining operating costs for operating the powertrain system at the candidate powertrain system operating point associated with the power loss from the torque machine (56,72) and based upon the temperature of the torque machine (56,72).
