Zusammenfassung:To provide an automatic transmission control device capable of reducing processing load without degrading control responsiveness.SOLUTION: A control device 7 controls electric current to one or more solenoids among a plurality of solenoids disposed corresponding to a plurality of gear stages to form a gear stage of a transmission mechanism in any of the prescribed plurality of stages. The control device 7 discriminates an object solenoid (for example, 11c) as an operation object from non-object solenoids (for example, 11a, 11b, 11d), when the gear stage is changed to a change destination gear stage, when the gear stage is changeable from a change original gear stage to the change destination gear stage or during the change. The control device 7 controls electric current of the non-object solenoids by applying a current control system of a processing load lighter than that of the current control system of the object solenoid by performing current feedback control to the object solenoid (U1-U5), and performing the current feed forward control on the non-object solenoids (U1-U2, U6, U5).SELECTED DRAWING: Figure 9 【課題】制御応答性を低下させることなく、処理負荷を低減できるようにした自動変速機制御装置を提供する。【解決手段】制御装置7は、変速機構のギヤ段を所定の複数段の何れかのギヤ段に形成するため、前記複数のギヤ段に対応して設けられた複数のソレノイドのうち何れか一つ以上のソレノイドに電流制御する。そして制御装置7は、ギヤ段を変更元ギヤ段から変更先ギヤ段に変更可能性のあるとき又は変更中に、変更先ギヤ段に変更するときに操作対象となる対象ソレノイド(例えば11c)と非対象ソレノイド(例えば11a,11b,11d)とを区別する。そして制御装置7は、例えば対象ソレノイドには電流フィードバック制御し(U1〜U5)、非対象ソレノイドには電流フィードフォワード制御を行う(U1〜U2、U6、U5)ことで、対象ソレノイドの電流制御方式よりも処理負荷の軽い電流制御方式を適用して非対象ソレノイドを電流制御する。【選択図】図9
