    Abstract: A vehicle includes a first axle, a second axle, an engine having a crankshaft, a transmission having an input member that is operatively connected to the crankshaft and an output member that is operatively connected to the first axle, a first motor having a first rotor operatively connected to the crankshaft, a second motor having a second rotor that is operatively connected to the second axle, and a controller being operatively connected to the engine, the first motor, and the second motor.

    Abstract: A method for controlling a hybrid powertrain includes the following steps: (a) receiving, via a control module, a torque request; (b) commanding, via the control module, the first clutch of an automatic transmission to shift to a disengaged position in response to the torque request; (c) commanding, via the control module, an electric motor-generator to transmit torque to an internal combustion engine until a speed of a second clutch is substantially synchronized with a speed of the internal combustion engine; and (d) commanding, via the control module, the second clutch to shift to the engaged position after the speed of the second clutch is substantially synchronized with the speed of the internal combustion engine. The automatic transmission shifts a transmission speed ratio from an initial speed ratio to a subsequent speed ratio when the second clutch is in the engaged position.

    Abstract: A plug-in hybrid vehicle includes a hybrid powertrain system and an energy storage device. A method for operating the hybrid powertrain system includes initially operating the hybrid powertrain system in a charge-depletion mode to reduce a state-of-charge (SOC) of an energy storage device. In response to an operator request, the hybrid powertrain system operates in an opportunity charging mode to opportunistically charge the energy storage device to increase the SOC of the energy storage device during a trip prior to achieving a minimum SOC that is associated with triggering operation in a charge sustaining mode.

    Abstract: A vehicle includes an engine, power inverter module, transmission, engine brake, and control system. The transmission has a stationary member, gearbox, and electric traction motor controlled via pulse width modulation. The engine brake selectively connects the engine to the stationary member in an electric vehicle drive mode. The control system executes a method to detect a requested autostart of the engine during the electric vehicle drive mode, disconnects the engine from the stationary member via the engine brake in response to the detected requested autostart, determines a driver-requested output torque and a maximum output torque of the transmission, and executes one of an engine self-lifting control routine and a motor over-modulation routine when the driver-requested output torque exceeds the calculated maximum output torque by less than a calibrated threshold, both routines when the driver-requested output torque exceeds the calculated maximum output torque by more than the calibrated threshold.
