1001-11 ABSTRACT OF THE INVENTION The present invention relates to a hydraulic control method for a continuously variable speed change gear mechanism and, more particularly, to such a method in which, by switching a driving frequency of a pressure control valve arrangement in order to change a hydraulic pressure in accord with an oil temperature of a hydraulic circuit, a proper oil pressure is assured even at low temperatures where oil viscosity is large, and a clutch pressure and the like are suitably maintained, thereby enabling operability to be improved and further relates to a pressure valve drive control method for such a mechanism in which, by switching a driving frequency of a pressure control valve arrangement in order to change an oil pressure in accord with vehicle velocity, the durability of the pressure control valve arrangement in a high speed mode is improved and vibration of the vehicle body due to pressure fluctuation in a low speed running mode is prevented.
