To provide a rank travel system that stabilizes a change of an inter-vehicular distance, on the basis of an excess tractional force change caused by a loading change and a gradient change and by making use of a retarder function provided in a power system.SOLUTION: A rank travel system for making a plurality of vehicles travel in a rank includes an engine, an engine retarder, an automatic transmission, a transmission retarder, an electronic control brake, a parking brake, a forward recognition device, a longitudinal acceleration sensor and an inter-vehicular communication device. An excess tractional force is calculated by detecting self-weight and a road grade, and traveling is performed in a setting in which a following vehicle has higher retarder ability and in a range in which the accelerating/decelerating ability of the vehicle with the lowest excess tractional force among the vehicles constituting the rank is not exceeded.SELECTED DRAWING: Figure 15

    【課題】積載変化・勾配変化による余剰牽引力変化を踏まえ、且つ、動力系に備わるリターダ機能を生かして、車間距離変化を安定させる隊列走行システムを提供する。【解決手段】車両が複数台で列を組んで走行する隊列走行システムにおいて、エンジン、エンジンリターダ、自動ミッション、ミッションリターダ、電子制御ブレーキ、駐車ブレーキ、前方認識装置、前後加速度センサ、車々間通信装置を備え、且つ自重及び道路勾配を検出して余剰牽引力を算出して、隊列を構成する車両の中で最も余剰牽引力が低い車両の加減速能力を超えない範囲、且つ、後続車ほどリターダ能力が高くなる設定で走行する。【選択図】 図15
