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： A control system of a vehicular drive system is provided with a controller that reduces regeneration torque of a second motor when an automatic transmission that is shifted down during coasting is in an inertia phase. By reducing the regenerating torque of the second motor during the inertia phase, the amount of work required for producing regeneration torque of the second motor is reduced, and the rotational speed of a power transmitting member coupled to a differential unit can be easily raised, whereby shift shock at the time of shifting is favorably reduced.
