A drive system includes an engine, a first differential mechanism that is connected to the engine and transmits rotation of the engine, a second differential mechanism that connects the first differential mechanism with drive wheels, a switching device that changes a speed ratio of the first differential mechanism, a first running condition, and a second running condition. The second differential mechanism has a first rotational element connected to an output element of the first differential mechanism, a second rotational element connected to a first rotating machine, and a third rotational element connected to a second rotating machine and the drive wheels. The first running condition is a running condition in which the vehicle runs using the second rotating machine as a power source, while differentially operating the first differential mechanism. The second running condition is a running condition in which the vehicle runs using the second rotating machine as a power source, without differentially operating the first differential mechanism. A region in which the vehicle runs in the second running condition in the case where the engine cannot start by itself (S10-N) is larger than that in the case where the engine can start by itself (S10-Y).

A driving device 1-1 for a hybrid vehicle includes a transmission unit capable of outputting a rotation of an engine 1 while changing rotating speed of the engine; and a first rotating electric machine MG1. The first rotating electric machine MG1 is configured to supply a torque for increasing the rotating speed of the engine at the time of starting up of the engine 1 to the engine 1 through the transmission unit. At the time of starting up of the engine 1, the gear shift stage of the transmission unit is switched to an overdrive state. Thus, a torque sufficient for starting up of the engine 1 can be supplied to the engine, and hence the engine 1 can be appropriately started up.

Providing a control device of a vehicle drive device capable of improving vehicle fuel efficiency by adjusting a torque of an electric motor to control an operating point of an engine. A first electric motor MG1, a second electric motor MG2, and a torque converter 16 make up a continuously variable transmission 60 as a whole and an engine operating point control means 70 provides an engine operating point control in which a first electric motor torque T MG1 is adjusted to control an operating point of an engine 12 during an engine running. Therefore, since a continuously variable transmission operation of the continuously variable transmission 60 can be performed by adjusting the first electric motor torque T MG1 (basically, regenerative torque) and the continuously variable transmission operation of the continuously variable transmission 60 enables the operating point of the engine 12 to be controlled without being constrained by a turbine rotation speed Nt, the engine 12 can be driven at an operating point optimal for the fuel efficiency improvement, for example, and the vehicle fuel efficiency can be improved.

An engine rotation speed does not change before and after shifting, so that a driver does not feel a sense of discomfort or unease. An electric vehicle drive control device includes a differential device in which a first rotational element is connected to a first electric motor, a second rotational element is connected to a second electric motor via a transmission shaft (15), and a third rotational element is connected to an engine (11); a transmission (18) for shifting a speed of a rotation transferred to the transmission shaft (15); compensating torque calculation processing means for calculating an inertia compensating torque that compensates a change in a rotation speed caused by inertia while the transmission (18) performs shifting; and target torque correction processing means for correcting a target torque for the first electric motor in accordance with the inertia compensating torque. With this arrangement, a change in an engine rotation speed due to inertia and a control delay can be prevented, and it is also possible to prevent an inertia torque from being generated in the engine (11).
