Abstract: PURPOSE: A fail safe hydraulic system of an automatic transmission is provided to realize a safe travel by preventing the occurrence of interlock in a power train regardless of the sticking position of a valve spool. CONSTITUTION: A second clutch(C2) and a first brake(B1) are supplied with the output pressure of a C2/B1 control valve(52) controlled by a C2/B1 control solenoid valve(50). The output pressure of the C2/B1 control valve is switched to two paths by a C2/B1 switch valve(54). One of the paths is communicated with the second clutch via a first fail safe valve(56) while the other path is communicated with the first brake via a second fail safe valve(58). The hydraulic pressure supplied to the second clutch is discharged via the C2/B1 switch valve and the fist fail safe valve. The hydraulic pressure supplied to the first brake is discharged via the C2/B1 control valve and the second fail safe valve. The output pressure of a C1 control valve(62) is applied to a first clutch via two paths. One of the paths is communicated with a first clutch(C1). The other path operates as a control pressure to second and third fails safe valves(58,64) and supplies hydraulic pressure to a first friction element via a first shuttle valve. Then, first and second brake pressures are released. The first brake pressure generated in the C2/B1 switch valve is supplied only when the second fail safe valve is switched over.

Abstract: PURPOSE: A hydraulic control system and a transmission control method of an automatic transmission are provided to improve shift characteristics, to simply control speed change, and to variably control line pressure in a high-speed travel. CONSTITUTION: Line pressure is supplied to a forward/backward movement pressure pipe by the operation of a manual valve(210). Line pressure is selectively supplied to three clutch units(310,320,33) and two brake units(340,350). Three pressure control valves(230,240,250) are independently controlled by three solenoid valves(260,270,280) on/off controlled depending on the throttle opening degree and vehicle speed. Line pressure supplied from the pressure control valves are selectively supplied to the clutch units and the brake units by changing a path via control valves(360,370,380,390). Since the pressure control valves are independently controlled by respective solenoid valves, speed change to respective speed ranges from the neutral range is possible. A fourth solenoid valve(170) is duty-controlled by a transmission control unit(400) at a third speed or a fourth speed. Thus, variable line pressure control is possible. Accordingly, the operating shock of the clutches and the brake due to rapid rise of line pressure is reduced in a high-speed travel.

Abstract: PURPOSE: A power train of an automatic transmission for a vehicle and an oil pressure controlling system for controlling the transmission improves a shift quality, a running performance by using an engine brake, a failsafe mode and one-way clutch. CONSTITUTION: Four advance speeds and one reverse speed are realized by combining two single pinion planetary gear sets(8,10). A line pressure varying device varies line pressure on second, third, fourth speeds. A speed change controlling device varies six range pressures. A variable device controls an engine brake. Thus, the engine brake is operated only on the top step of each range, thereby improving a shift quality. Further, a failsafe mode is dualized, thereby improving a running performance. Furthermore, a released control is performed by a one-way clutch on all the speed change ranges, thereby improving the shift quality.
