Abstract: PURPOSE: A continuously variable automatic transmission hydraulic control apparatus of a hybrid vehicle is provided to improve the efficiency of a continuously variable automatic transmission by automatically securing a pulley pressure and solenoid valve supplying pressure which are necessary for rapid restart of a vehicle. CONSTITUTION: A continuously variable automatic transmission hydraulic control apparatus comprises a D-N control valve(7). The fluid pressure from a line regulator valve(1) is supplied to a solenoid feed valve(5) through a second regulator valve(3) according to the change of clutch lubricant pressure and driving pulley control pressure about follower control pressure. The fluid pressure from the line regulator valve is directly supplied to the solenoid feed valve. The D-N control valve converts the state of the fluid pressure supplied to the solenoid feed valve through the second regulator valve and the state of the fluid pressure directly supplied to the solenoid feed valve.

Abstract: An oil pressure control apparatus of a continuously variable transmission vehicle is provided to secure driving stability due to a trouble of a shift control unit by supplying oil pressure of a stable state to a first pulley of a start clutch by a spring installed in a shift control valve in spite of a limp home effect for stopping an engine due to the trouble of the shift control unit. A shift ratio control valve(100) includes springs(110) which are installed at both ends of an inside of a shift ratio control valve body. A limp home valve(200) is switched selectively according to a trouble of a shift control unit. An oil pressure line(300) is connected to the shift ratio control valve body. One end of the oil pressure line is extended to the outside of the shift ratio control valve body. The other end of the oil pressure line is connected to a front end of the limp home valve. The oil line is used for performing a driving operation in a predetermined shift ratio in spite of the trouble of the shift control unit.
