    摘要： A powertrain system includes a transmission operative to transfer power between a plurality of power actuators and an output member, and an energy storage device. A method for controlling the powertrain system includes establishing a first set of electric power limits and a second set of electric power limits for the energy storage device, determining a preferred input power from a first power actuator based upon the first set of electric power limits, determining a first set of power constraints for constraining input power from the first power actuator and a second set of power constraints for constraining output power from the output member based upon a second set of electric power limits, and controlling operation of the powertrain system based upon the preferred input power, the first set of power constraints, and the second set of power constraints.

    摘要： A method for controlling the cranking of an engine of a vehicle powertrain system having a rechargeable energy storage system that is adapted to provide electric power to an electric machine, wherein the system is adapted to exit from the engine crank state as a function of an output voltage of the energy storage system to the electric machine during the crank state, if the output voltage is less than a crank undervoltage threshold for a predetermined crank time. According to the method, the crank undervoltage threshold is a function of the number of failed start attempts, generally decreasing as a function of the number of failed start attempts. The predetermined crank time is a function of a magnitude of a difference between the output voltage and the crank undervoltage threshold.

    摘要： An exemplary method for operating a hybrid vehicle in the event that there is a problem with an auxiliary power source, such as an internal combustion engine or a fuel cell. According to one embodiment, the method provides a power management scheme for a variety of situations where an auxiliary power source experiences a problem; this may include situations where an internal combustion engine runs out of fuel, where there is a mechanical or electrical malfunction, or any other instance where the auxiliary power source is unable to generate and/or provide electrical energy for the hybrid vehicle. The power management scheme conserves the vehicle's primary power source, which is typically a battery, in order to provide the hybrid vehicle with an extended driving range.
