Zusammenfassung:	PROBLEM TO BE SOLVED: To balance between a fuel economy improvement and an acceleration-deceleration response speed in auto-cruising of a hybrid vehicle.SOLUTION: A transmission 20 includes: a primary transmission mechanism 21 for reducing the speed of rotary driving of a diesel engine 10, the rotation transmitted via a clutch 15; and a secondary transmission mechanism 22 for adjusting speed reduction ratios of the primary transmission mechanism 21. A control apparatus 80 controls an operation of a hybrid vehicle 100 in auto-cruise. A shift lever 81 allows a driver of the hybrid vehicle 100 to manually shift gears of the transmission 20. In a case where (1) the clutch 15 is in a connection state, (2) the secondary transmission mechanism 22 is in a neutral state and (3) a motor-generator 33 is in a regeneration state, the control apparatus 80 releases a neutral state of the secondary transmission mechanism 22 under the condition of the driver operating the shift lever 81 to down-shift the transmission 20, as trigger.SELECTED DRAWING: Figure 1 【課題】ハイブリッド車両のオートクルージングにおける燃費向上と加減速の応答速度とを両立させる。【解決手段】トランスミッション２０は、クラッチ１５を介して伝達されるディーゼルエンジン１０の回転駆動を減速する主変速機構２１と主変速機構２１の変速比を調整する副変速機構２２とを含む。制御装置８０は、ハイブリッド車両１００のオートクルーズにおける動作を制御する。シフトレバー８１は、ハイブリッド車両１００の運転手がトランスミッション２０を手動でギアシフトする。制御装置８０は、（１）クラッチ１５が接続状態、（２）副変速機構２２がニュートラル状態、かつ（３）モータジェネレータ３３が回生状態、の場合において、運転手がシフトレバー８１を操作してトランスミッション２０をシフトダウンすることを契機として、副変速機構２２のニュートラル状態を解除する。【選択図】図１
