Abstract:
1. A control device for controlling a belt-type continuously variable transmission, wherein said belt-type continuously variable transmission comprises: two pulley shafts arranged in parallel at a predetermined distance; movable sheaves arranged on the pulley shafts and slidable on corresponding pulley shafts in axial directions of the pulley shafts, respectively; fixed sheaves arranged on the corresponding pulley shafts to face corresponding movable sheaves so as to form grooves between the fixed sheaves and the movable sheaves, respectively; a belt wound on the grooves between the movable sheaves and the fixed sheaves facing one another; a first actuator that is provided to a one of the movable sheaves so as to press the one movable sheave toward a corresponding one of the fixed sheaves to generate a belt pinching pressure on the one movable sheave; a second actuator and a torque cam that are provided to an other movable sheave so as to press the other movable sheave toward an other fixed sheave to generate a belt pinching pressure on the other movable sheave; and an electronic control unit including an input torque deriving arrangement that
