Zusammenfassung:To provide a shift control device that makes control responsiveness and shift shock satisfactory when accelerating or decelerating while setting a gear stage from a full release state.SOLUTION: A shift control device: calculates a target gear stage to be set in a transmission on the basis of drive data including vehicle speeds of a vehicle, and in the case where a predetermined target gear stage is calculated on the basis of the drive data when the vehicle travels while releasing all of a plurality of engagement mechanisms, determines whether or not the target gear stage is the gear stage on a lower speed side than an early gear stage, which is calculated from the drive data just before the target gear stage is calculated, (step S3); and when determining that the target gear stage is the gear stage on a lower speed side than the early gear stage, performs control of engaging the engagement mechanism so as to set the target gear stage without performing control of setting the early gear stage (step S5).SELECTED DRAWING: Figure 5 【課題】全解放状態からギヤ段を設定して加減速する場合に制御応答性や変速ショックを良好にする変速制御装置を提供する。【解決手段】車両の車速を含む駆動データに基づいて変速機で設定するべき目標ギヤ段を算出し、複数の係合機構の全てを解放して車両が走行している際に駆動データに基づいて所定の目標ギヤ段が算出された場合に、目標ギヤ段が、目標ギヤ段が算出された直前の駆動データから算出される初期ギヤ段より低速側のギヤ段か否かを判断し(ステップS3)、目標ギヤ段が初期ギヤ段より低速側のギヤ段であることが判断された場合には、初期ギヤ段を設定する制御を行うことなく目標ギヤ段を設定するように係合機構を係合させる制御(ステップS5)を行う。【選択図】図5
