PROBLEM TO BE SOLVED: To provide a technology for making a motor size compact in a V-belt type non-stage transmission including an actuator having a motor as a driving source.SOLUTION: As shown in Fig.(a), a thrust force CM1 of an actuator is set to be larger than 0 at the time of shift-up (a shift-up area less than a vehicle speed S) under an economical mode. That is, a motor is controlled in such a way that the actuator may generate an additional thrust added to the thrust force CM2 of a centrifugal weight. In turn, under a sport mode, as shown in Fig.(b), the thrust force CM1 of the actuator at the time of shift-up (a shift-up area less than a vehicle speed S) is set to be smaller than 0. That is, the motor is controlled in such a way that the actuator may generate a resistance thrust force resisting against the thrust force CM2 of the centrifugal weight. The motor is acted not only as an assisting means but also as a brake means to cause the actuator to be effectively utilized under both transmission modes, thereby it is possible to reduce a motor capacity and attain a compact size motor. |
