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： This invention relates to a control device for a hybrid vehicle power transmitting apparatus. A heat generation control is executed to increase a heat generation amount of an electric motor M1 when a differential portion 11 is placed in a non-differential state and a temperature of a shifting mechanism 10 is less than a given transmitting apparatus temperature determining value TEMP11. This allows the first electric motor M1 to develop a heat with which the temperature of a shifting mechanism 10 is promptly raised, thereby promptly completing a warm-up of the shifting mechanism 10 to achieve improved fuel consumption.

摘要： A vehicular drive system includes a standby control apparatus which controls a switch to standby control based on a switching line graph that has a standby region that places a differential state switching device in a state just before it starts to apply. This standby region is located between a differential region and a locked region on the switching line graph. Accordingly, when the differential state switching device enters the standby region from the differential region, it is placed in a state just before it starts to apply. As a result, the differential state switching device is quickly able to have the necessary torque capacity when the engine torque is increased, which suppresses a decrease in the durability of the differential state switching device.
