| Abstract(E) | Recently, by addition of Real Driving Emissions (RDE), the man-hour of vehicle development is on the increase for the verification of exhaust emissions in actual vehicle driving. This study proposes a development tool that enables front-loading of RDE using Model Based Development (MBD) at the product planning stage. The worst case of driving condition related to exhaust emission is required to select devices and develop controls that comply with RDE regulations at the product planning stage. Using this MBD tool, the virtual driving evaluations were predicted NOx emissions for each driving pattern. As a result, the worst case of driving condition was extracted, and guidelines for countermeasures to reduce exhaust emissions were provided. |
