摘要： This invention relates to a control device for a vehicular power transmitting device. The control device has shifting-point altering means 108 operative such that when a second electric motor M2 is operated with priority to obtain a charging efficiency and/or electric power generating efficiency, a shifting point for a vehicle to run under a decelerating state (during a coast running state) is altered to a point on a higher vehicle speed than that at which a shifting point for a running-performance-conscious state is set. Therefore, when the second electric motor M2 is operated with priority for generating electric power, a downshift is initiated at a high vehicle speed than that at which the downshift is initiated at a shifting point for a running-performance-conscious state. This increases a rotation speed NM2 of the second electric motor M2, resulting in an increase in regeneration amount (electric power generation amount) of the second electric motor M2.

摘要： The present invention provides, in a vehicular power transmitting apparatus including a differential portion electrically controlled, a control device which can quickly decrease the engine rotation speed, even if the operational state of an electric motor is limited. An engine-stop controlling means (112) includes limiting means for limiting the differential state of a differential portion (11) by a switching brake (B0) and a switching clutch (C0) when the operational state of a first electric motor (M1) is limited. Therefore, a torque in a direction for decreasing a rotation speed (NE) of an engine (8) is applied by limiting the differential state of the differential portion (11), for example, in a vehicle stopped state. As a result, the rotation speed (NE) of the engine (8) is quickly decreased to pass through a resonance point in a short time, whereby occurrence of resonance phenomena can be prevented.

摘要： When a reduction in a supply hydraulic pressure to a second shift portion is sensed, an engagement command of C0 clutch is generated so that a power split device (electrical differential portion) is brought into a locked state. In the locked state, a sun gear, a carrier rotated by an engine and a ring gear rotated by a second MG integrally rotate, whereby inertia is increased. Thus, high-speed rotation of a transmission member corresponding to an input shaft of the second shift portion can be prevented.

摘要： When an engine is driven on a different type of fuel (for example, ethanol-containing fuel) from a reference fuel (for example, gasoline) and the engine torque is thus greater than that produced when the engine is driven on the reference fuel, a differential state control device expands a non-differential range compared to that at the time when the reference fuel is used. Thus, in the case where a plurality of types of fuel including the reference fuel are supplied to the engine, the advantage of switching a power distribution mechanism between a differential enabled state and a non-differential state can be fully utilized in correspondence with engine torque characteristics which may vary in accordance with the type of fuel for the engine. As a result, the fuel consumption rate can be reduced in correspondence with the plurality of types of fuel supplied to the engine, for example.

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： When an engine stop control is executed while an automatic ratio shift portion is in a neutral state, a switching clutch is operated, so that a differential portion carrier of a differential portion planetary gear device that is linked to an engine, and a differential portion ring gear linked the automatic ratio shift portion are integrally rotated. Therefore, along with the engine stop control, the rotation speed of the rotating elements of the differential portion planetary gear device is reduced while the rotating elements are integrally rotated or substantially integrally rotated. Since the rotating elements are rotated integrally or substantially integrally, the high rotation speed of the differential portion ring gear linked to the automatic ratio shift portion, which tends to have a heightened rotation speed particularly during the neutral state, is prevented.
