ABSTRACT:
When a reduction in a supply hydraulic pressure to a second shift portion is sensed, an engagement command of C0clutch is generated so that a power split device (electrical differential portion) is brought into a locked state. In the locked state, a sun gear, a carrier rotated by an engine and a ring gear rotated by a second MG integrally rotate, whereby inertia is increased. Thus, high-speed rotation of a transmission member corresponding to an input shaft of the second shift portion can be prevented.
