    • In a planetary gear type stepped automatic transmission, a gear shift control to shift a gear shift stage between a first gear shift stage and a second gear shift stage is performed by a first shift control section by referring to a first gear shift control data used when the gear shift stage is switched between the first gear shift stage and the second gear shift stage, an abnormality state due to a failure of at least one of a first frictional engaging element (B3) and a second frictional engaging element (B1) is detected, and an abnormality state gear shift control is performed to shift the gear shift stage between a third gear shift stage (for example, first speed) and a fourth gear shift stage (for example, 2.5 speed) by the first shift control section, while forcefully releasing the first frictional engaging element (B3), when detecting the abnormality state.
    • 在行星齿轮式有级式自动变速器中,通过参照第一变速控制部分执行第一变速级和第二变速级之间的变速级的变速控制, 在第一变速级和第二变速级之间切换变速级,由于第一摩擦接合元件(B3)和第二摩擦接合元件(B1)中的至少一个的故障而检测到异常状态 ,并且执行异常状态变速控制,以通过第一变速控制部分在第三变速级(例如,第一速度)和第四变速级(例如,2.5速度)之间变速变速档,而 当检测到异常状态时强制地释放第一摩擦接合元件(B3)。
