PURPOSE: To attain the desirable synchronization of both transmission parts by performing the feedback control of a first and a second transmission parts taking account of the speed change progress of the other parties mutually in addition to their own speed change progress.
CONSTITUTION: The speed change progress detecting means 202, 204 of a first and a second transmission parts 60, 40 detect the drum rotating speed Nc2(k), Nco(k) of the respective clutches so as to obtain deviations ec2(k), eco(k) with the target rotating speed. The control input determining means 206, 208 of the first and second transmission parts 60, 40 then input feedback information on the deviation and control input of the other parties mutually in addition to feedback information on their own deviation ec2(k), eco(k) and control input, and integrate these inputs to determine the control input. The speed change progress of both parties is thus synchronized desirably to reduce the generation of speed change shock.
