Abstract
Vehicle conceptual investigation at early stage of development has played significant role in accordance with increasingly complicated powertrain system and stricter regulation of fuel economy. This study presents a practical methodology for designing vehicle concept at earlier stage of development. This methodology consists of simulation tool chain that can predict vehicle acceleration and fuel consumption. In this paper, we demonstrate specific results of series-parallel-type plug-in hybrid electric vehicle (PHEV) as an example. Then it’s proved that the vehicle simulation can define engine and motor power distribution according to vehicle target and requirement.
