摘要： PROBLEM TO BE SOLVED: To ensure high oil pressure without worsening workability.
SOLUTION: A primary regulator valve 1400 is connected with a first oil passage 1304. The primary regulator valve 1400 controls line pressure by control pressure of a linear solenoid (SLS) 1600 and energizing force of a spring 1406. A pressure relief valve 1500 is connected with a second oil passage 1306 branched from the first oil passage. The pressure relief valve 1500 controls line pressure by control pressure of the linear solenoid (SLS) 1600 and energizing force of a spring 1506. The pressure relief valve 1500 drains oil pressure when line pressure becomes higher than a value controlled by the primary regulator valve 1400 by fuel of the primary regulator valve 1400.

摘要： PROBLEM TO BE SOLVED: To provide an oil pressure control device for a continuously variable transmission capable of controlling two flow control valves using one solenoid valve.
SOLUTION: The hydraulic control device to control the oil pressure of the continuously variable transmission 200 including a control valve 230 for increasing the speed and a control valve 250 for decelerating the speed is equipped with an ECT_ECU 100 to emit a command about the output of the oil pressure to the solenoid valve 270, the solenoid valve 270 to generate the oil pressure on the basis of the given command, the first oil passage to connect the solenoid valve 270 with the control valve 230 for increasing the speed, and the second oil passage to connect the solenoid valve 270 with the control valve for deceleration 250. When the oil pressure lying within the predetermined, first range is emitted, the control valve 230 opens the oil passage, and the continuously variable transmission 200 increases the speed. When the oil pressure lying within the predetermined second range is fed, the control valve 250 opens the oil passage, and the continuously variable transmission 200 decreases the speed.

摘要： PROBLEM TO BE SOLVED: To prevent abrupt downshift, a line pressure reduction, and an overrun of a driving source due to a valve stick in a transmission control valve for downshift without any deterioration in downshifting transmission responsiveness.
SOLUTION: When a valve element 54d in a flow control valve 54 for upshift is moved to the upshift side (upside) by means of an upshift signal pressure PVD, a downshift port 54c is shut off to block flow of working fluid to the flow control valve 58 for the downshifting side, so that even in the case of the valve stick while the flow control valve 58 is in a full-open condition, the flow of the working fluid toward the flow control valve 58 side is prevented by the upshifting control, and consequently, excessive downshift is prevented. In comparison with restriction of a drain opening carried out for preventing excessive downshift in the valve stick, excellent speed change responsiveness can be obtained because the flow control valve 58 is controlled to be opened to the full open according to accelerator operation quantity and the like in an ordinary time.

摘要翻译：要解决的问题：防止由于在用于降档的变速控制阀中的阀杆引起的急速降档，行程压力下降和驱动源超速，而不会降低换档响应性。解决方案：当用于升挡的流量控制阀54中的阀元件54d通过升档信号压力PVD移动到升档侧（上侧）时，切换挡板54c以阻止工作流体流向流量控制用于降档侧的阀58，使得即使当流量控制阀58处于完全打开状态时阀棒的情况下，通过升档控制来防止工作流体朝向流量控制阀58侧的流动，因此防止了过低的降档。与为了防止阀杆过度降档而进行排水开口的限制相比，由于根据加速器操作量等将流量控制阀58控制为全开，所以可以获得极好的变速响应性一个普通的时间。

摘要： PROBLEM TO BE SOLVED: To provide a control device of a vehicle, preventing automatic start from being performed under a situation that operation failure of an automatic transmission resulted from impossibility of normal driving of solenoid valves potentially occurs. SOLUTION: An ECU 32 is configured to perform automatic stop and start control for repeatedly performing automatic stop and automatic start. The ECU32 identifies coil resistance values of the solenoid valves 33, 34, 52, 53 based on a hydraulic oil temperature detected by an oil temperature sensor 40 and determines whether or not the solenoid valves 33, 34, 52, 53 can be driven normally. The ECU 32 performs automatic stop of an internal combustion engine 11 when identifying that the coil resistance values of the solenoid valves 33, 34, 52, 53 are smaller than the maximum resistance value for driving the solenoid valves 33, 34, 52, 53 normally and when another automatic stop condition is satisfied.
