To provide a control system for carrying out a speed change operation of a geared transmission mechanism continuously by controlling a continuously variable transmission mechanism. A continuously variable transmission mechanism configured to increase and decrease speeds of a first and a second output discs simultaneously, and a geared transmission mechanism configured to change a speed change ratio stepwise are connected in series. The output discs are connected individually with intermediate shafts. The control system is adapted to synchronize a rotational speed of a switching mechanism and a rotational speed of a member to be engaged with the switching mechanism, by tilting a rolling member when carrying out a speed change in the geared transmission mechanism thereby increasing a rotational speed of one of the intermediate shaft while decreasing a rotational speed of the other intermediate shaft (at steps S3, S4 and S5). |
