PROBLEM TO BE SOLVED: To suppress a sense of incongruity due to display of a tachometer in starting.SOLUTION: A control device 1 is disposed in a vehicle including: an engine 3; an automatic transmission 4 including a torque converter 10; and a tachometer 2 for displaying a value on the basis of actual engine speed Ne of the engine 3. The control device 1 includes: a determination part 1A which determines success and failure of a start condition including the fact that the torque converter 10 is in a non-lock-up state and in starting of the vehicle; and a display control part 1B which performs performance control for displaying virtual engine speed Na instead of the actual engine speed Ne on the tachometer 2 when the determination part 1A determines that a start condition is established. The display control part 1B refers the actual engine speed Ne and input engine speed Nc close to a driving wheel 5 side than the torque converter 10 in the automatic transmission 4 to calculate performance engine speed Naa, and displays the performance engine speed Naa as the virtual engine speed Na on the tachometer 2.SELECTED DRAWING: Figure 1 【課題】発進時において、タコメータの表示に起因した違和感を抑制する。【解決手段】制御装置１は、エンジン３と、トルクコンバータ１０を含む自動変速機４と、エンジン３の実回転数Ｎｅに基づく値を表示するタコメータ２とを具備した車両に設けられる。制御装置１には、トルクコンバータ１０が非ロックアップ状態であること、および、車両の発進時であることを含む開始条件の成否を判定する判定部１Ａと、判定部１Ａにより開始条件が成立したと判定された場合に、実回転数Ｎｅに代えて仮想回転数Ｎａをタコメータ２に表示させる演出制御を実施する表示制御部１Ｂとが設けられる。表示制御部１Ｂは、実回転数Ｎｅと自動変速機４におけるトルクコンバータ１０よりも駆動輪５側の入力回転数Ｎｃとを参照して演出用回転数Ｎａａを算出するとともに、演出用回転数Ｎａａを仮想回転数Ｎａとしてタコメータ２に表示させる。【選択図】図１
