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 shifts are performed at the same time in first and second transmitting portions and the gear ratios of those transmitting portions change in opposite directions, a simultaneous shift control unit controls the shift in the first transmitting portion using a first electric motor and controls the shift in the second transmitting portion using a second electric motor such that the shift in one transmitting portion, from among the first and second transmitting portions, ends while the shift in the other transmitting portion is being performed. The shifts in the two transmitting portions will not end at the same time so the amount of shift shock felt by an occupant can be reduced. Also, the shifts in the two transmitting portions are controlled by the first and second electric motors so the progress of the shifts in those transmitting portions can be actively adjusted.

摘要： When the shift position is changed to the drive position, the amount of oil that is supplied to an automatic shift unit is increased by a larger amount as the standby hydraulic pressure is lower. Therefore, even if the standby hydraulic pressure is decreased, the required hydraulic pressure is more easily achieved when the shift position is changed to the drive position. Therefore, it is possible to decrease the standby hydraulic pressure without slowing down the response to the automatic shift unit to the hydraulic pressure and reducing the useful life of the automatic shift unit. Thus, the amount of electricity consumed by the electric oil pump is reduced. As a result, it is possible to enhance the fuel efficiency.

摘要翻译： 当换档位置改变为驱动位置时，供给到自动换档单元的油量随着备用液压压力的降低而增加较大的量。 因此，即使在备用液压降低的情况下，当换挡位置变为驱动位置时，也能够更容易地实现所需的液压。 因此，可以在不使对自动换档单元对液压的响应减慢的同时降低备用液压并且降低自动换档单元的使用寿命。 因此，电动油泵消耗的电量减少。 结果，能够提高燃料效率。

摘要： A control device for hybrid vehicle is provided with property alter means 88 that is operative based on whether or not an EV running mode is set and alters a given property used for determining demanded output torque TOUTt of a transmission mechanism 10 by referring to an accelerator opening Acc. This suppresses occurrence of engine startup to meet a requirement for the EV running mode to be initiated. The property alter means 88 alters the given property such that during an EV running mode turn-on state, demanded output torque TOUTt determined based on the accelerator opening Acc has a lower value than that set for an EV running mode turn-off state. That is, this causes a drop in sensitivity of demanded output torque TOUTt determined based on the accelerator opening Acc. Thus, the occurrence of engine startup induced upon depressive operation of an accelerator pedal during the EV running mode is suppressed.
