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.

Control apparatus for a hybrid vehicle drive system

A carrier is implemented which is capable of reducing the number of parts and the number of bonding steps. The carrier includes a pair of holding members that hold from both sides in an axial direction L a pinion shaft supporting a pinion gear. A first holding member as one of the pair of holding members includes a coupling portion extending in the axial direction L toward a second holding member as the other holding member. The second holding member is a disc-like member, and has an external outer peripheral gear integrally formed in its outer peripheral portion. The coupling portion is bonded to a coupling bonding portion provided on a radially inner side Rof the outer peripheral gear in the second holding member.
