Driver Modeling and Simulation for RDE Testing: Effect of driver behavior on representative test results

摘要

In early development stages, several real driving emissions (RDE) test activities have to be performed in virtual environments in addition to real test drives. Besides serving as a reliable virtual control instance, the driver model must reflect a realistic driver behavior in these tests. Real test measurements are used to tune the model and compare test results to show to what extent real tests can be performed in a virtual environment. Because fuel consumption and emissions are significantly influenced by the driving behavior, different driving styles are specified by a set of intuitive parameters. In this paper, a sophisticated driver model is used to perform RDE tests and the results are collected and compared.
