Modeling the drive train for two Parallel Hybrid Electric Vehicles in MATLAB/Simulink

A simulation model for the calculation of the gas consumption of two different Hybrid Electric Vehicles with parallel drive train is presented. Thereby the components of the combustion engine drive train are modeled by efficiency maps, whereas the efficiencies of the components of the electric drive train (Nickel-Metal-Hydride-Battery, voltage source inverter, permanent magnet synchronous or cage induction machine) are determined by static loss models. For the estimation of the temperatures within the inverter and the electric machines dynamic thermal multi-body models have been designed and implemented. A universally valid energy management controls the drives. By this energy management the drive train losses are minimized.
