    Abstract: In a power transmission system, a ring gear of a first speed reducer and a ring gear of a second speed reducer are coupled to each other and have the same rotational axis. An engagement portion between the ring gear and a planetary gear is formed such that, when a first motor generates a rotational torque in the forward direction, a force acts on the ring gear in a direction approaching the second speed reducer in the rotational axis direction. An engagement portion between the ring gear and a planetary gear is formed such that, when a second motor generates a rotational torque in the forward direction, a force acts on the ring gear of the second speed reducer in a direction of approaching the first speed reducer in the rotational axis direction.

    Abstract: A method of managing available operating states in an electrified powertrain includes: identifying a plurality of operating states; determining an allowable hardware operating speed range for each of the plurality of operating states; determining a real operating speed range for each of the plurality of operating states; determining an ideal operating speed range for each of the plurality of operating states, the ideal operating speed range being a subset of the allowable real operating speed range; indicating an operating state of the plurality of operating states as ideal-allowed if an actual output speed of the electrified powertrain is within the ideal operating speed range for that operating state; and commanding the electrified powertrain to operate within one of the operating states that is indicated as ideal-allowed.

    Abstract: The hybrid vehicle has a motor generator disposed in a power transmission path and performing as an electric motor and an electric generator, a direct injection engine configured to execute an ignition start in which fuel is injected into any cylinder with a piston stopped in an expansion stroke and ignited for the start, and an engine connecting/disconnecting clutch of friction engagement type directly connecting and interrupting the direct injection engine to/from the motor generator. The control device of the hybrid vehicle has an MG creep mode in which the motor generator is used as an electric motor and rotationally driven at a predetermined first rotation speed to generate a creep torque while the engine connecting/disconnecting clutch is interrupted and the direct injection engine is stopped, and a charging creep mode in which the direct injection engine is operated at a predetermined second rotation speed higher than the first rotation speed to generate the creep torque with the motor generator used as an electric generator to charge a battery while the engine connecting/disconnecting clutch is connected, the control device performs the ignition start of the direct injection engine during the MG creep mode and provides connection control of the engine connecting/disconnecting clutch after a rotation speed of the direct injection engine exceeds a rotation speed of the motor generator to raise the rotation speed of the motor generator and directly connect the direct injection engine to the motor generator when a transition is made from the MG creep mode to the charging creep mode.

    Abstract: A hybrid engine assembly may include an engine having a crankshaft, a supplemental shaft mechanically coupled to the crankshaft, a flywheel energy storage assembly, and an auxiliary device. A flywheel clutch may selectively couple the flywheel assembly to the crankshaft. The assembly may be selectively operated in an engine restart mode by directly coupling the flywheel energy storage assembly to the crankshaft prior to starting the engine, and in an auxiliary power mode by directly coupling the flywheel energy storage assembly to the auxiliary device.
