摘要： PROBLEM TO BE SOLVED: To prevent downshift due to shortfall in oil balance in an oil pump. SOLUTION: To eliminate failure to generate oil pressure designated by an oil pump 80 due to reduction of an engine rotation number by controlling line pressure in accordance with oil balance of the oil pump 80 based on the engine rotation number and oil temperature by a pulley pressure control part 202 in either case of selected determination between detection of change from a drive range into a non-drive range or from the non-drive range to the drive range and a lapse of prescribed time, and detection of the non-drive range. Ratio of the line pressure in accordance with the oil balance to the line pressure to be designated is multiplied by secondary pressure, and the secondary pressure is controlled based on the obtained value. A pulley ratio can thus be maintained without downshifting in a belt type continuously variable transmission. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To prevent a cavitation noise generated in a hydraulic pump at a high rotation of an engine.
SOLUTION: A line pressure control part 203 for controlling line pressure calculates a target value of line pressure from inputted input torque information, a target gear ratio, or the like. A line pressure setting part 205 sets an upper limit value of line pressure according to an inputted range signal when the engine speed is a prescribed engine speed or higher. The line pressure control part 203 controls the line pressure, when the line pressure upper limit value is set, so as not to exceed the set line pressure upper limit, to regulate the rise of line pressure. Accordingly, the cavitation noise generated in the hydraulic pump 80 which generates the base pressure of line pressure at a high rotation of the engine can be prevented.
