Simulation-Based Development of an Energy Management System for an Innovative Power-Splitting Hybrid Drive Train with a Double Rotating Electric Machine

This paper results from a governmental founded research project which includes the development, demonstration and evaluation of an innovative power-splitting hybrid drive train. The rear axle is driven electrically; the front axle is driven by a combustion engine (ICE) via a double rotating electric machine which enables a power-splitting operation of the presented hybrid drive train. An Energy-Management-System, which controls the components and contains a load strategy for the ICE, was simulation-based developed and optimized for the most efficient operation of the total system. Comparative simulations of alternative powertrains were analyzed to show the consumption advantage of the presented technology.
