摘要： A control device is provided for a hybrid vehicle power transmitting apparatus wherein when a fuel type supplied to an engine is altered, a drop in startability of the engine resulting from alteration on the fuel type is suppressed. Fuel-type determining means determines the fuel type for use in operating the engine, based on which a reactive control representing a control of reactive control of a second electric motor counteracting rotational resistance of the engine during engine startup, is altered. Accordingly, second-motor torque (reactive torque) for increasing an engine rotation speed during engine startup is adjusted depending on the fuel type, thereby increasing a temperature of fuel compressed and expanded in the engine, to a level available to initiate an ignition. This prevents the alteration of the fuel type from causing degradation in startability of the engine when the fuel type supplied to the engine is altered.

摘要： A vehicular power transmitting system, which permits the power transmitting system to provide a sufficient vehicle drive force even when an input of an electric energy into an electric-energy storage device is restricted and which reduces the electric efficiency of at least one of an first electric motor and a second electric motor, when an input of an electric energy into a chargeable electric-energy storage device is restricted, during an operation of an engine. This provides a vehicle drive force and generation of the electric energy by at least one of the first electric motor and the second electric motor, so that the amount of electric energy generated by the first electric motor is reduced, and/or the amount of electric energy consumed by the second electric motor is increased, whereby a sufficient vehicle drive force can be obtained even when the input into the electric-energy storage device is restricted.

摘要： A control device for a vehicle power transmitting apparatus is disclosed, having an electrically controlled differential portion operative to control an operating state of an electric motor to control a differential state, and a shifting portion forming part of a power transmitting path between the electrically controlled differential portion and drive wheels, which can minimize deterioration in power performance and degradation in controllability during the shifting. Shift interval altering means 70 is provided for altering an interval L from an operation initiation causing an automatic shifting portion 20 to execute a shifting, to an actual shift initiation depending on a kind of the shifting. This enables an appropriate interval L to be determined for the shifting, thereby obtaining adequate power performance while capable of avoiding a first electric motor M1 from operating in a region outside an operating range. Thus, degradation in controllability is minimized.

摘要： A control device is provided for a power train including: a differential mechanism having a first rotating element linked to a first rotary electric machine, a second rotating element linked to a second rotary electric machine and a third rotating element linked to an internal combustion engine; a switching mechanism that switches between a first state that permits relative rotation of the first, second and third rotating elements, and a second state that prohibits relative rotation thereof; and a transmission mechanism connected to the differential mechanism which transmits torque from the differential mechanism to a wheel. The control device includes: a first control portion that controls the switching mechanism so as to switch between the first and second states; and a second control portion that compensates for an amount of change in the torque transmitted to the wheel when the switching between the two states is performed.

摘要： A hybrid vehicle driving device includes: a first differential mechanism connected to an engine and transmitting a rotation of the engine; a second differential mechanism connecting the first differential mechanism and a drive wheel; engagement devices changing a speed of the first differential mechanism; and a valve arranged in a hydraulic circuit and regulating the engagement devices from simultaneously engaging. The second differential mechanism includes a first rotation element connected to an output element of the first differential mechanism, a second rotation element connected to a first rotating machine, and a third rotation element connected to a second rotating machine and the drive wheel. The valve regulates the engagement devices from simultaneously engaging at a time of traveling with the engine, and tolerates the engagement devices from simultaneously engaging at a time of traveling with the first rotating machine and the second rotating machine.
