This presentation systematically elaborates on the key technical pathway adopted by FAW Hongqi to construct a virtual calibration system for hybrid vehicles based on the WAVE-RT real-time simulation tool. By converting one-dimensional WAVE models into real-time models and integrating them into a Hardware-in-the-Loop (HiL) system, a closed loop is formed with real ECUs/HCUs, enabling automated front-loaded calibration of the engine air-charge model, VVT, and hybrid strategies. The system covers various hybrid architectures, including P1P3, P2, P1P3P4, and range extenders, achieving a convergence accuracy of over 95% for key engine model parameters. The simulation deviation in vehicle fuel consumption under WLTC conditions is optimized from 8% to 4%, significantly compressing the calibration cycle and supporting energy consumption optimization and OBD diagnostic validation.
