Abstract
Real driving emission (RDE) testing method is adopted for Light-duty vehicles. In the future, RDE testing method will be also adopted for Heavy-duty vehicles. However, it is difficult for Heavy-duty vehicles to estimate by using RDE testing method. The reason is the Heavy-duty vehicles have a lot of vehicle families and powertrain types. Therefore, we considered the test method of RDE for heavy-duty vehicles by using new approach of Model Based Testing (MBT), which combinates HILS and engine bench system. In this report, in order to construct the MBT method of RDE, we considered the reproduction method of the real road conditions. We could obtain the road data easily and high precision.
