摘要： A hydraulic control system of a friction device where fail-safe is required is provided with one oil pressure switch and one pressure changeover valve. The pressure changeover valve is switched by auxiliary oil pressure based on an operation of the oil pressure control valve. When an auxiliary port communicates with an input port and the pressure changeover valve is switched to the filling determination side, the oil pressure switch is turned on and “filling determination” can be carried out. When the auxiliary port is disconnected from the input port, the pressure changeover valve is switched to the fail-safe determination side. The oil pressure switch is supplied with the same driving oil pressure as of the friction device and “fail-safe determination” can be carried out from the on/off state of the oil pressure switch.
