To provide a vehicle automatic transmission control device capable of effectively warming up an engine by intentionally increasing a load of the engine through relatively simply control of an automatic transmission.SOLUTION: A vehicle automatic transmission control device comprises: a torque converter provided between an output shaft of an engine and an input shaft of an automatic transmission; and control means for controlling the automatic transmission. The automatic transmission has an engagement mechanism which includes at least either one or a plurality of clutches for switching engagement and disengagement between rotating elements or one or a plurality of brakes for switching engagement and disengagement between the rotating element and a stationary element. The control means performs stop time engine warming-up control for controlling the engagement and disengagement of the engagement mechanism when determining that a request is made for warming up an engine while a vehicle is stopped so that drive force is not transmitted to an output member and the input shaft is put into a fixed state.SELECTED DRAWING: Figure 8
【課題】比較的に簡易な自動変速機の制御によってエンジンの負荷を意図的に上げてエンジンの効果的な暖機を行うことが可能な車両用自動変速機の制御装置を提供する。【解決手段】エンジンの出力軸と自動変速機の入力軸との間に設けたトルクコンバータと、自動変速機を制御する制御手段と、を備え、自動変速機は、回転要素同士の係合・非係合を切り替える一又は複数のクラッチと回転要素と固定要素との係合・非係合を切り替える一又は複数のブレーキの少なくともいずれかを含む係合機構を備え、制御手段は、車両の停車中にエンジンの暖機要求があると判断した場合に、係合機構の係合・非係合を制御することで、出力部材には駆動力が伝達されず、かつ、入力軸が固定された状態とする停車時エンジン暖機制御を行う。【選択図】図8
