CONTROL DEVICE FOR VEHICULAR DRIVING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a control device suppressing the occurrence of a variable speed shock while miniaturizing a driving device or improving fuel consumption in the vehicular driving device equipped with a differential mechanism and a motor provided in the differential mechanism.

SOLUTION: A change-over clutch CO or a change-over brake BO 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. During the speed change of an automatic transmission part 20 in the continuously variable speed state of a differential part 11, the engaging pressure of an engaging device of an automatic transmission part 20 is controlled by an engaging pressure control means 84 so that transmission member rotating speed N18is changed to a predetermined value to achieve both variable speed responsiveness of a good feeling and variable speed responsiveness to easily suppress the variable speed shock. The occurrence of the variable speed shock is thereby suppressed.
