摘要：
An automatic transmission is controlled by the use of estimation of a disturbance so that an input shaft rotates as desired to suppress shock caused during a speed-change transient mode. The disturbance is estimated from an actual rotational speed of an input shaft of the automatic transmission and a control command value to a pressure regulating device based on a predetermined transfer function model. The disturbance may be estimated alternatively by the use of a speed change in the rotational speed of the input shaft.
