摘要： A circuit for controlling hydraulic pressure of a torque converter that includes an engagement hydraulic pressure chamber independently installed in a fluid operation chamber enclosed by a front cover and an impeller and having engagement hydraulic pressure supplied to engage a lock-up clutch may include a torque converter control valve stably decreasing line pressure and supplying the decreased line pressure as operation hydraulic pressure of the torque converter, a torque converter pressure control valve controlled by a linear solenoid valve to control D range pressure and supply the controlled D range pressure to the engagement hydraulic pressure chamber, and a lock-up switch valve controlled by the linear solenoid valve to supply the hydraulic pressure supplied from the torque converter control valve as control pressure of the torque converter pressure control valve and supply exhaust hydraulic pressure of the torque converter as control pressure of the torque converter control valve.

摘要： A hydraulic control system of an automatic transmission may be applied to an automatic transmission in which a reverse speed stage is engaged by engagement of first and second friction elements. The hydraulic control system may include: a first solenoid valve being a normally open type and controlling a line pressure to generate a first hydraulic pressure; a second solenoid valve being a normally closed type and controlling the line pressure to generate a second hydraulic pressure; first and second switch valves, the first switch valve selectively supplying the first hydraulic pressure to the second switch valve; and a fail-safe valve selectively supplying the first hydraulic pressure or the second hydraulic pressure to the second friction element, wherein the second switch valve selectively supplies the first hydraulic pressure supplied from the first switch valve or a reverse speed pressure to the first friction element.
