を特徴とする自動変速機のクリープ制御装置。[Scope of Claim for Utility Model Registration] A gear train in which the engine rotation input via a fluid coupling is appropriately changed in speed by engagement and release operations of a frictional engagement element and outputted to the driving wheels. In an automatic transmission that controls the amount of creep when the engine is idling in a driving range by controlling the amount of slip, there is a means for detecting the engine speed, and an actual speed detected by the engine speed detecting means and a predetermined speed. means for comparing the set rotation speed with a predetermined rotation speed at the time of abnormal decrease; and neutral setting means for completely releasing the frictional engagement element when the actual rotation speed becomes lower than the predetermined rotation speed according to the rotation speed comparison means. A creep control device for an automatic transmission, characterized in that it is provided with the following.
