Feasibility Study of Estimation Method for Real-World Fuel Consumption by Using a Virtual Test Driving


RDE (Real Driving Emissions) will be mandatory soon for emission regulations. PEMS (Portable Emission Measurement System) is one of existing methods to measure RDE with real test vehicle. Otherwise, some of negative aspects of PEMS are time consuming and costly method. This paper presents a possibility to use more effective way with CAE technology regarding the RDE. This study aims RDE testing with virtual environment and analyzes which parameters in some boundary conditions is most effective to RDE. Fuel consumption was estimated by this method as 1ˢᵗ applied performance. The results show this prediction method, using virtual test driving tool, is very effective for vehicle powertrain R&D. This paper also shows a verification of this simulation result by real driving with the same vehicle on the same real route.自動車の燃費や排気性能において,測定モード時と実走行時における乖離が指摘されている.本研究ではバーチャルテストドライビングによりRDEを予測する手法を提案し,同手法が効率的なRDE予測を可能とすることを示すと同時に,走行条件やパワートレインの違いなど燃料消費率に及ぼす影響を系統的に解析した.
