| Abstract(E) | This study focuses on developing robust exhaust emission reduction technologies under real-world driving conditions. Real driving involves complex variables such as traffic flow, driver behavior, and environmental factors, which significantly affect emission control performance. Hybrid vehicles, through optimized engine-motor power management, have shown potential for reducing fuel consumption and emissions. To efficiently evaluate emission trends and control strategies, the authors constructed a digital twin development environment capable of simulating realistic driving scenarios. Using this platform, NOx emission hotspots were identified, and the influence of driver behavior on emission levels was confirmed. Control adjustments at key points led to reductions in both average NOx emissions and their variability. Compared to conventional road testing, the digital twin approach enabled significant improvements in development efficiency and reproducibility, supporting the advancement of emission reduction technologies toward a zero-emission future. |
