摘要： A control system for an automatic transmission that does not require a cut-off valve, and that can inhibit a reverse control even if a detection unit for detecting a shift range fails. The control system includes a first friction engagement element, which is engaged in predetermined forward and reverse shift speeds, a detection unit that detects a shift range from shift ranges that include a forward range and a reverse range; a failure judgment unit for judging failure of the detection unit, and an avoidance unit for shifting to a forward shift speed that does not engage the first friction engagement element if the failure judgment unit determines that the detection unit has failed.
摘要翻译： 即使用于检测换档范围的检测单元也不能使用，也不需要截止阀的自动变速器的控制系统，也能够抑制反向控制。 所述控制系统包括以预定的正向和反向换档速度接合的第一摩擦接合元件，检测单元，其检测包括前进范围和倒档范围的换档范围的换档范围; 用于判断检测单元的故障的故障判断单元，以及如果故障判断单元确定检测单元已经失败，则用于切换到不接合第一摩擦接合元件的前进档位的回避单元。
