CONTROL DEVICE FOR VEHICLE DRIVING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a control device for a vehicle driving device which can raise a power transmission efficiency by comprehensively controlling the gear ratio of a whole vehicle driving device with respect to the vehicle driving device equipped with an electric type differential section and a continuously variable shift section.

SOLUTION: Such a case that a switching brake B0 or a switching clutch C0 is engaged, and a total continuously variable gear ratio γT is changed by a continuously variable shift section 20 is compared with such a case that the switching clutch C0 and the switching brake B0 are both released, and the total continuously variable gear ratio γT is changed by an electric type differential section 11 and a continuously variable shift section 20, and one of those cases whose fuel consumption is smaller is selected for operation. Thus, fuel consumption is sharply improved in a vehicle equipped with the electric type differential section 11 and the continuously variable shift section 20.
