摘要： The present invention relates to a method for controlling an automatic transmission of a vehicle which is capable of continuously changing a transmission ratio (Rt) and transmission coefficient (Ct). The method is three fold, that is, an initial stage control procedure, a special stage control procedure and a normal stage control procedure having priority in operation in this order.At the initial stage control procedure, Rt and Ct are determined, according to a plurality of indices representing a state of the vehicle, so that the vehicle is accelerated effectively, in general.At the special stage control procedure, Rt and Ct are determined, when a propelling force transmitting path for transmitting propelling force from an engine to the ground is disconnected at least at one part, so that a shock due to a recovery of said propelling force transmitting path is minimized.At the normal stage control procedure, Rt and Ct are determined so that the vehicle responds to the operation of the driver swiftly.
