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. The controller is configured to selectively cause the engine to enter a deceleration fuel cut off mode, cause the transmission input torque to increase to zero, cause the torque of the second motor to decrease as the transmission input torque increases such that the sum of the first axle torque and the second axle torque remains substantially constant as the transmission input torque increases to zero.

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 hybrid transmission includes a transmission having a selectable clutch device effective when engaged to mechanically couple an internal combustion engine to a first axle at a fixed engine speed to axle speed ratio. A method for starting the engine includes executing an engine start event including spinning and fueling the engine such that an engine speed to axle speed ratio exceeds the fixed engine speed to axle speed ratio, and engaging said selectable clutch device after the engine speed to axle speed ratio exceeds the fixed engine speed to axle speed ratio.

Abstract: A transmission includes an input member, an output member, and a stationary member. First and second planetary gearsets each have respective first, second, and third members. A first motor/generator has a first rotor operatively connected to one of the members of the planetary gearsets for unitary rotation therewith. A second motor/generator has a second rotor operatively connected to one of the members of the planetary gearsets for unitary rotation therewith. The transmission also includes first, second, and third torque transmitting devices operative to selectively connect members of the planetary gearsets with the input member, the stationary member, or with other members of the planetary gearsets to provide two electric vehicle modes, two electrically variable modes, and a fixed gear ratio mode of transmission operation.
