To calculate target engine torque by properly determining the timing of a start of an inertia phase.SOLUTION: A control device comprises an input torque acquisition part, a clutch torque acquisition part, a torque determination part, a gear change ratio calculation part, and a torque calculation part. The input torque acquisition part acquires input torque which is inputted to an input shaft of an automatic transmission. The clutch torque acquisition part acquires the clutch torque of a clutch which is operated when a gear change stage of the automatic transmission is changed. The torque determination part determines that the input torque and the clutch torque are changed from a first state that one of the input torque and the clutch torque is larger than the other is changed into a second state that the other is larger than the one. The gear change ratio calculation part calculates an intermediate gear change ratio between a pre-change gear change ratio and a post-change gear change ratio. The torque calculation part performs torque calculation processing for calculating target engine torque on the basis of the intermediate gear the input torque and the clutch torque hange ratio on condition that the torque determination part determines that the input torque and the clutch torque are switched to the second state from the first state.SELECTED DRAWING: Figure 4 【課題】イナーシャ相の開始のタイミングを適切に判定して目標エンジントルクを算出する。【解決手段】制御装置は、入力トルク取得部、クラッチトルク取得部、トルク判定部、変速比算出部、及びトルク算出部を備えている。入力トルク取得部は、自動変速機の入力軸に入力される入力トルクを取得する。クラッチトルク取得部は、自動変速機の変速段を変更する際に操作されるクラッチのクラッチトルクを取得する。トルク判定部は、入力トルク及びクラッチトルクの一方が他方よりも大きい第１状態から他方が一方よりも大きい第２状態に切り替わったことを判定する。変速比算出部は、変更前変速比と変更後変速比との間の中間変速比を算出する。トルク算出部は、中間変速比に基づいて目標エンジントルクを算出するトルク算出処理を、トルク判定部により入力トルク及びクラッチトルクが第１状態から第２状態に切り替わったと判定されたことを条件に実行する。【選択図】図４
