Abstract: A multi-mode powertrain system including an internal combustion engine, a high-voltage electric machine and a high-voltage electric power system is described. A method for controlling the multi-mode powertrain system includes, in response to an operator initiating a jumpstart, electrically connecting the high-voltage electric power system to a remote electric power source and energizing contactors between the high-voltage electric power system and the remote electric power source. Electric power flow through an auxiliary power module electrically connected to the high-voltage electric power system that supplies electric power to an accessory device is minimized. Engine starting parameters are modified, and the internal combustion engine is started by controlling, via a controller, the high-voltage electric machine to spin the internal combustion engine, and controlling operation of the internal combustion engine based upon the modified engine starting parameters to effect starting.

Abstract: An off-board charging device disposed to electrically charge an electric energy storage system via an electrical charging system on-board a vehicle is described. This includes an electric machine electrically connected to the electric energy storage system and is disposed to supply propulsion effort to the vehicle. A method for controlling the off-board charging device includes determining severity of a drive cycle that occurs prior to a charging event for the electric energy storage system. A charging profile is determined based upon the severity of the drive cycle. A controller commands operation of the off-board charging device based upon the charging profile.

Abstract: A method of controlling a transmission having a gearbox and a pump operable to circulate a fluid through the gearbox, includes sensing an acceleration of the vehicle, and adjusting an operating state of the pump. The operating state of the pump is adjusted to change the operating state of the pump from an initial operating state, to an adjusted operating state, when the acceleration of the vehicle is greater than an acceleration threshold. When the acceleration of the vehicle decreases from being greater than the acceleration threshold to being below the acceleration threshold, the operating state of the pump is returned to the initial operating state. The operating state of the pump may include a speed of the pump, a control signal representing a fluid flow rate for the current speed of the pump, or a fluid flow circuit for supplying the fluid to the pump.
