Abstract

A control apparatus for a hybrid vehicle drive system, which uses electric energy stored in a battery and includes a drive mode switching portion configured to bring a clutch or a brake into an engaged state, for switching the drive system from an EV drive mode, in which a vehicle drive force is generated by at least one of first and second electric motors when a crankshaft of an engine is connected to a housing, to a constant-speed-ratio drive mode, in which the vehicle drive force is generated by at least one of the first and second electric motors when a ratio of an output speed of the drive system to a speed of a rotary motion received from the engine is constant, when an operating speed of the first or second electric motor is at or greater than a predetermined threshold value in the EV drive mode.
