摘要： A clutch apply control valve switches between a first position and a second position based on a control pressure PDS1 and a control pressure PDS2. When both the control pressure PDS1 and the control pressure PDS2 are output, the clutch apply control valve switches from the first position to the second position and outputs the control pressure PDS2. As a result, a lockup control valve switches to an OFF position. Accordingly, a dedicated solenoid valve for controlling operation of the clutch apply control valve can be eliminated, thus reducing both size and cost while enabling a lockup clutch to be released even if there is an ON failure of a solenoid valve.

摘要： A first orifice is provided in a first fluid passage upstream of a cooler, and a second orifice is provided in a second fluid passage. The flowrates of hydraulic fluid flowing through the first and second fluid passages are regulated by the first and second orifices, respectively, and are thus suppressed from becoming excessive. Also, the downstream side of the second fluid passage is connected to the first fluid passage between the first orifice and the cooler, and a lubrication passage is connected to the first fluid passage downstream of the cooler. Accordingly, the lubrication passage is a single passage and the cooler and the lubrication passage are arranged in series so the cooler flowrate and the lubrication flowrate are the same. As a result, the flowrate of hydraulic fluid that flows out from a secondary regulator valve to the upstream side of an oil pump can be increased.

摘要： The line hydraulic pressure setting portion sets the line hydraulic pressure PL, which is the base pressure for the required shift control pressure Pin and the required belt clamping pressure Pd, based on the higher of the required pressures Pin and Pd. At this time, if the continuously variable transmission is to be shifted up, the required Pin calculating portion calculates the required shift control pressure Pin based on one of the target speed ratio γ* and the actual speed ratio γ with which the required shift pressure Pv is calculated to be higher than with the other. As such, the required shift control pressure Pin is set to the minimum necessary level for shifting up the continuously variable transmission and the line hydraulic pressure PL is appropriately set to a level for obtaining the required shift control pressure Pin.
