Hybrid drive system

A rotation speed controller performs a rotation speed control to allow the rotation speed of a first rotating electrical machine to be equal to a start up target value, when an internal combustion engine is started while a frictional engagement device is disengaged. An engagement controller controls a non-synchronization engagement of the frictional engagement device and allows the frictional engagement device to be in a direct engagement state when performing the rotation speed control. A start up instruction unit gives a start up instruction with respect to the internal combustion engine on condition of being directly engaged. The rotation speed controller sets the start up target value so that a rotation speed at the time of a direct connection, which is a rotation speed of the engine while in direct engagement, becomes a start up rotation speed that is set within a startable rotation speed range of the engine.
