Abstract: 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.

Abstract: A control device for a vehicular drive system controls an engine rotation speed (NE) in a way not to exceed an engine upper limit rotation speed (NELIM). The engine upper limit rotation speed is altered depending on a second electric motor rotation speed (NM2) such that a second electric motor increasing possible rotation speed (NM2max), influenced with the engine upper limit rotation speed (NELIM), is altered depending on the second electric motor rotation speed (NM2). Consequently, when the second electric motor rotation speed (NM2) is relatively high, the engine upper limit rotation speed (NELIM) can be lowered, and the second electric motor increasing possible rotation speed (NM2max) can be altered to a lower level for suppressing an increase in rotation speed of a second electric motor (M2). Thus, the second electric motor is improved in durability thereof.

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.
