摘要:   Closed-Loop coupling of simulation models and testing environment allows front-loading of system integration,and thus validation and calibration in early development phases.This reduces the necessary time and costs for the development of new power-trains.With the support of co-simulation methodologies,a seamless transfer can be applied from component design,to model-in-the-loop(MiL)and hardware-in-the-loop(HiL)tests.The reutilization of engine models from desktop simulations in component test bench-es saves extra modelling effort with maintained model accuracy.For real-time applications,a crank angle resolved combustion engine model built in GT-Power is described in this paper.It is cali-brated with test bench measurement data and integrated into a SIMULINK-based vehicle co-simulation.The co-simulation includes the engine model,a dual clutch transmission model,a vehicle dynamics model,and a 12V electrical power net model.After system inte-gration and validation based on real vehicle measurement results on a desktop PC,the co-simulation is transferred to a real-time HiL-simulator.As an exemplary use of the HiL-based methodology,a component testing scenario,coupled to the virtual real-time simulation envi-ronment,is evaluated.The 12V electrical power net of the co-simulation model is replaced with real hardware including the battery and the alternator.A novel power net management strategy is evaluated with the closed-loop real-time simulation in order to validate the ca-pacity of the engine model.It is demonstrated that the efforts for model adaptation from desktop to real-time application are acceptable and leading to consistent results.
