A Study of Fuel Economy Improvement of Small Delivery Hybrid Trucks

小型配送用ハイブリッドトラックの燃費調査および燃費改善の検討

Control methods improving fuel economy of hybrid trucks were investigated. Performances of hybrid trucks in fuel economy which are shown in catalog specifications are relatively better than that of normal diesel trucks that have no hybrid systems. Nevertheless, hybrid trucks users report that advantages of fuel economy by hybrid trucks at the real traffic conditions are little. In this study, the cause of low improvement in fuel economy by hybrid trucks was investigated. Firstly, a simulation model of a hybrid truck was constructed and the model was validated with results measured by an actual hybrid truck with chassis dynamometer. Secondly, control methods of the model were investigated to operate an engine in high efficiency conditions.小型配送用トラックにおいては,ディーゼルトラックに対するハイブリッドトラックの燃費に関する優位性が見られないとの声が挙がっている.本報では,シャシダイナモ試験装置にてディーゼルおよびハイブリッドトラックの燃費値を計測し,その要因を調査した.また,ハイブリッド小型配送トラックの燃費改善方策を検討した.
