Abstract: In an operation of controlling an automatic transmission, an engagement pressure for each hydraulic servo in a normal operation is determined so that none of friction engagement elements slips at each shift speed in the normal operation, and so that in case of a failure in which the friction engagement element that is supposed to be disengaged in the normal operation is engaged, one of the friction engagement elements slips, and thus one of the shift speeds is established. In the control operation, upon detection of a failure state in which a gear ratio after a shift operation is a gear ratio of a shift speed different from a shift speed to be established, the slipping friction engagement element is disengaged, and the shift speed that is different from the shift speed to be established is temporarily retained.

Abstract translation: 在自动变速器的控制操作中，确定正常运行时每个液压伺服系统的接合压力，使得在正常运行中，每个换档速度下摩擦接合元件都不会滑动，因此， 假定在正常操作中分离的摩擦接合元件接合，摩擦接合元件中的一个滑动，因此建立了一个换档速度。 在控制动作中，在检测到变速操作后的变速比是与要设定的变速速度不同的变速比的变速比的故障状态时，滑动摩擦接合元件脱离， 不同于要建立的班次暂时保留。
