CONTROL DEVICE FOR VEHICULAR DRIVING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a control device suppressing a variable speed shock in shifting a stepped transmission while miniaturizing a driving device or improving fuel consumption in the vehicular driving device equipped with a differential mechanism and the stepped transmission provided in a power transmission line from the differential mechanism to a driving wheel.

SOLUTION: A change-over clutch C0 or a change-over brake B0 is provided to switch a transmission mechanism 10 into a continuously variable speed state and a stepped variable speed state to thereby provide the driving device combining both advantages of a fuel consumption improving effect of a transmission in which a variable speed ratio is electrically changed, and the high transmission efficiency of a gear type transmission which mechanically transmits power. In clutch-to-clutch shift transmission in the continuously variable speed state of a differential part 11, an inertia phase is started using a second motor M2 by a hybrid control means 52 prior to the start of an inertia phase following the change-over of engaging pressure. The variable speed start time of the differential part 11 is thereby stabilized to suppress the variable speed shock.
