Dongfeng Commercial Vehicles (DFCV) is developing powertrain controls for a hybrid light truck. To support this development; a virtual integration platform is being implemented; using Modelica models and Functional Mock-up Units (FMUs) for the engine/EMS; gearbox; MCU/e-motors; driveline; tyres and longitudinal dymamics. Simulink models and/or c-code of the Hybrid Control Unit (HCU) and Transmission Control Unit (TCU) are also integrated in the plat-form to achieve closed-loop simulation. The virtual integration allows reproducing accurately the overall vehicle behavior and is used for optimization of gearshifts; hybrid mode switches and hybrid drive strategies.
