Vehicles with hybrid powertrains provide a promising concept for the reduction of fuel consumption and exhaust-gas emissions.A computer-based simulation program has been developed to simulate hybrid powertrains with respect to these aspects and to compare all conceivable component configurations and control strategies. Mechanical, electric and hydraulic components are described in a similar fashion by using universal quantities for the description of energy flows. Together with the modularity of the simulation models for the systems, the components, the control strategies and the controls, to be selected from a library, this approach provides a huge freedom for the user in defining powertrain models and components in various levels of accuracy. From a user-defined driving pattern, the program calculates energy flows, energy losses and other component-state variables as functions of time. Fuel consumption and exhaust-gas emissions can be calculated combining the engine operating points with stationary fuel and emission maps. Simulation studies for several hybride powertrains, confirm that the program is an easy, yet powerful tool for comparison and optimization of various powertrain designs
