摘要： PROBLEM TO BE SOLVED: To provide a parking control device which is improved in responsiveness without causing the lowering of oil pressure for releasing parking.
SOLUTION: In an initial stage for releasing the parking, a large force can be taken out of an output rod 33 fixed to a small-diameter piston 32 since pressure-receiving areas of a large-diameter piston 31 and the small-diameter piston 32 are large, a parking rod cam 15 is driven in this state by a distance equivalent to a moving distance of a parking rod 14 which elastically contacts with a support 17 and a parking pole 18, then the large-diameter piston 31 is stopped, only the small-diameter piston 32 is moved, and thereby the responsiveness for the introduction of oil pressure from an oil-pressure introduction port 36 is improved. In this state, the movement of the small-diameter piston 32 can be linked to the movement of the parking rod 14. Accordingly, since the oil pressure fed to a releasing cylinder 30 is reduced in amount as a whole, the lowering of the oil pressure for releasing the parking is not caused, and thus the favorable responsiveness can be obtained.

摘要翻译：要解决的问题：提供一种提高响应性的停车控制装置，而不会导致用于释放停车的油压降低。解决方案：在用于释放停车的初始阶段，由于大直径活塞31和小直径活塞31的受压面积，可以从固定到小直径活塞32的输出杆33中取出大的力，直径活塞32大，驻车杆凸轮15在该状态下被驱动相当于与支架17和停放杆18弹性接触的停车杆14的移动距离的距离，则大直径活塞31为停止，只有小径活塞32移动，从而提高了从油压引入口36引入油压的响应性。在这种状态下，小直径活塞32的移动可以与驻车杆14的运动相关联。因此，由于供给到释放缸30的油压整体上减少，所以油的降低不会引起释放停车的压力，因此可以获得良好的响应性。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a hydraulic control device for automatic transmissions which makes it unnecessary to arrange many valves and can prevent the deterioration of oil pressure responsiveness although it is the device that can prevent the occurrence of simultaneous engagement. SOLUTION: The hydraulic control device 20 outputs engagement pressures P SL1 -P SL5 from two of linear solenoid valves SL1-SL5 at normal time to form a gear shift. A fail-safe valve 30, which outputs a simultaneous engagement signal pressure P FSV when three or more engagement pressures P SL1 -P SL5 are inputted, is provided on this oil pressure control device 20. An original pressure selector valve 37 interrupts the original pressure of the linear solenoid valves SL1-SL5 to attain a neutral state when inputting the simultaneous engagement signal pressure P FSV from the fail-safe valve 30. It becomes unnecessary to provide many valves, so that it becomes unnecessary, too, to interpose a fail-safe valve between the linear solenoid valves and a hydraulic servo.

摘要： PROBLEM TO BE SOLVED: To provide an abnormality determination device of a linear solenoid valve for a vehicle which can exactly and easily detect an abnormality of a linear solenoid valve which controls the oil pressure of a hydraulic friction engagement device of a vehicle.
SOLUTION: The abnormality determination device includes: a speed change control means 108 which outputs a standby pressure command signal lower than a first fill-command signal for forming a temporary oil-pressure rise waveform while following the first fill-command signal; a pressure sensor SE for detecting the output oil pressure of the linear solenoid valve SL; and an abnormality determination means 116 which determines the occurrence of an abnormality when a lowering estimation value E indicating the degree of the lowering of the output oil pressure detected by the pressure sensor SE is lower than a preset abnormality determination value J. By this, since the abnormality determination is performed by utilizing difference of the variation of the output oil pressure from the linear solenoid valve SL at an abnormal time and that at a normal time, the abnormality when the linear solenoid valve SL is firmly seized after the start of the speed change control can exactly and easily be detected when a rise in the output oil pressure of the linear solenoid valve SL is started.
