Zusammenfassung:PROBLEM TO BE SOLVED: To provide an engine control device capable of more reliably suppressing shift shock even if one-position skip shifting is implemented.SOLUTION: Demarcation lines X1 to X4 separating determination areas A1 to A5 for determining a gear position are located between a synchronous rotating speed line having, as an inclination, a value proportional to a gear ratio of a low-speed gear position and a synchronous rotational speed line having, as an inclination, a value proportional to a gear ratio of the high-speed gear position out of two gear positions corresponding to the separated two determination areas and set to a lower velocity side than a line connecting vehicle average values on these synchronous rotating speed lines at the same engine rotating speed and to a higher velocity side than the synchronous rotating speed line of the low-speed gear position.SELECTED DRAWING: Figure 5 【課題】1段飛ばしの変速が実施された場合であってもより確実に変速ショックを抑えることのできるエンジンの制御装置を提供する。【解決手段】ギヤ段を判定する各判定領域A1〜A5どうしを区画する境界ラインX1〜X4を、区画する2つの判定領域にそれぞれ対応する2つのギヤ段のうち低速側のギヤ段のギヤ比に比例する値を傾きとする同期回転数ラインと高速側のギヤ段のギヤ比に比例する値を傾きとする同期回転数ラインとの間に位置して、同一エンジン回転数におけるこれら同期回転数ライン上の車速の平均値を結ぶラインよりも低車速側、かつ、上記低速側のギヤ段の同期回転数ラインよりも高車速側に設定する。【選択図】図5
