In recent years, RDE (Real Driving Emission) testing has become important in evaluating exhaust emissions and fuel efficiency. However, due to the many constraints on driving conditions and the cost, fuel efficiency estimation using simulation is effective. In this study, driver behavior such as stopping at traffic lights and decelerating on curves using a driver model is reproduced. Additionally, the regenerative energy in the simulation was modeled based on measurements from chassis dynamometer tests. As a result, the driver model was able to replicate the vehicle speed during actual road driving, and by reproducing regenerative energy during actual road driving, the model improved the accuracy of fuel efficiency predictions.
