Around the world, fuel economy and emission regulations for vehicles have become increasingly stringent year by year. In Europe, the real driving emission (RDE) testing was introduced for evaluating the emission at driving the road-going vehicles after September 2017. In order to effiency produce the actual vehicles, Each automobile manufacturer introduce the “Hardware In the Loop Simulator” (HILS) and “Engine In the Loop Simulator” (which is called the EILS or the extended HILS [1, 2]), which is combined with HILS and an actual engine. However, if the driver model used in the vehicle simulation (HILS, extended HILS) does not correctly simulate actual human driving behaviors, the model vehicle performances will differ from the actual vehicle performance. The fuel economy and emission characteristics are affected by the differences of the driver model control logic during the execution of vehicle simulation.
