Abstract: A control device for controlling a V-belt CVT (Continuously Variable Transmission) which is connectible to a vehicle engine and comprises a primary variator and a secondary variator. The control device has a plurality of sensors which generate electronic measured values, comprising an engine speed sensor which generates a first measured value, and a power sensor which generates a second measured value which is related to the torque of an output drive shaft connected to the secondary variator. The control device further comprises an electronic control unit which is adapted to control the V-belt CVT based on said measured values. A V-belt CVT having a control device as stated above, and a method for controlling such a V-belt CVT are also provided.
