Abstract:
A control device for a vehicle continuously variable transmission that includes: an input-side variable pulley of which an effective diameter is variable; an output-side variable pulley of which an effective diameter is variable; a transmission belt that is wound between the input-side variable pulley and the output-side variable pulley; and a check valve that, on the basis of a first pressure that is one of an input-side pressure applied to the input-side variable pulley and an output-side pressure applied to the output-side variable pulley, regulates a second pressure that is the other one of the input-side pressure and the output-side pressure includes: a control unit that, when the second pressure is regulated by the check valve, controls the first pressure on the basis of a pressure required to suppress a slip of the transmission belt and a pressure required to achieve a target speed ratio.
