Abstract: 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.
