徴とする無段変速機の制御装置。 An engine, a starting clutch that receives engine power into the input shaft, a primary pulley that is installed on the input shaft and whose effective diameter is variably controlled by fluid pressure, and a starting clutch that is installed on the output shaft and that controls the effective diameter of the primary pulley. The primary pulley is actuated by a secondary pulley whose effective diameter is variably controlled according to the movement of the primary pulley, a V-belt wound between both pulleys, and signals from the throttle valve opening sensor and engine speed sensor. In a control device for a continuously variable transmission that is equipped with a gear ratio control valve that controls the effective diameter and a clutch control valve that is activated by signals from both of the sensors and controls the control hydraulic pressure of the starting clutch, The present invention is characterized in that an opening change detector is provided to obtain a signal from the sensor and detect a rate of change or an acceleration of change in the opening of the throttle valve, and the clutch-connected engine rotational speed is changed in accordance with the signal from the detector. Control device for continuously variable transmission.
