| Abstract(J) | ハイブリッド車両のエンジン効率は燃費性能を左右する重要な指標であり，競合車両の正確な評価は開発方向の選定に重要である．CAN通信取得トルクによる簡易推定法，燃料流量計と燃焼圧による算出法，車両接続状態でエンジンと変速機間にトルクセンサーを設置した実測法の三手法を比較し，測定精度と実用性を評価した． Translation |
| Abstract(E) | Engine efficiency is a critical factor in determining fuel economy performance of hybrid vehicles, making accurate benchmarking of competitor vehicles essential for guiding development decisions. Three evaluation methods were investigated: a simplified estimation approach using engine torque acquired via CAN communication, a calculation method based on fuel flow meter and combustion pressure data, and a direct measurement approach with a torque sensor installed between the engine and transmission while connected to the vehicle. The measurement accuracy and practical applicability of each method were evaluated through mutual comparison of the engine efficiency results obtained. |
