摘要： PROBLEM TO BE SOLVED: To provide a shift control device for a six-speed type automatic transmission which is enabled to perform a fail-safe process even during the trouble of wire severance without improving an ECU or adding a fail-safe valve.
SOLUTION: A second on/off-solenoid valve S2 of a normal low type controls a spool position of a fourth shift valve 26. When disconnection occurs during energizing the second on/off-solenoid valve S2, a fourth on/off-solenoid valve S4 of a normal high type and a shuttle valve SB maintain the spool position of the fourth shift valve 26 before disconnection. The shuttle valve SB inputs the signal pressure of the second on/off-solenoid valve S2 and the fourth on/off-solenoid valve S4 and supplies one or both signal pressure to the fourth shift valve 26. The fourth on/off-solenoid valve S4 is controlled to be reversely synchronized with the energizing control of the second on/off-solenoid valve S2.

摘要翻译：要解决的问题：为了提供一种六速式自动变速器的变速控制装置，即使在断线的故障中也能够进行故障安全处理，而不改进ECU或增加故障安全阀。
解决方案：正常低型的第二开/关电磁阀S2控制第四换档阀26的阀芯位置。当在通电第二开/关电磁阀S2期间发生断开时，第四开/关正常高型的电磁阀S4和梭阀SB在断开连接之前保持第四换档阀26的阀芯位置。梭阀SB输入第二开/关电磁阀S2和第四开/关电磁阀S4的信号压力，并将一个或两个信号压力提供给第四换档阀26.第四开/关电磁阀 S4被控制为与第二开/关电磁阀S2的通电控制反向同步。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To enable the safe travel of a vehicle even by manually shifting to a third-, second-, or L-speed range during travelling at a 6th-speed in a D-range.
SOLUTION: An inhibitor valve 22 supplies 32L pressure from a manual valve 21 to a second hydraulic pressure chamber 26d of a fourth shift valve 26 in a state that a second on-off solenoid valve S2 is not energized. The inhibitor valve 22 interrupts the 32L pressure from the manual valve 21 to inhibit the supply low speed range limited 32L pressure to the second hydraulic pressure chamber 26d of the fourth shift valve 26 in a state that the second on-off solenoid valve S2 is energized. When the manual valve 21 is operated from a D-range of a 6th-speed or a predetermined speed or higher into a low-speed range (third-, second-, or L-speed range), an electronic control part 4 controls the second on-off solenoid valve S2 to be energized to constitute a 5th-speed until it gets to a speed lower than a predetermined speed.

摘要翻译：要解决的问题：即使在D档的第六速行驶期间，即使通过手动转换到第三，二或L速度范围，也能够使车辆的安全行驶。解决方案：在第二通电电磁阀S2未通电的状态下，抑制阀22将32L的压力从手动阀21供给到第四换挡阀26的第二液压室26d。抑制阀22在第二通电电磁阀S2通电的状态下，中断来自手动阀21的32L压力，以抑制向第四换流阀26的第二液压室26d限制的供给低速范围32L的压力。当手动阀21从第6速度或预定速度或更高速度的D-范围操作到低速范围（第三，第二，或L速度范围）时，电子控制部分4控制第二开关电磁阀S2被激励以构成第五速度，直到其达到低于预定速度的速度。版权所有（C）2008，JPO＆INPIT
