In expanding its activities in the field of internal combustion (ic) engines AVL is currently developing the so-called Universal Hybrid System (UHS) for light duty vehicles. It consists of an ic-engine, two electrical machines and a planetary gear box which distributed the power generated. This arrangement constitutes a multi-structural hybrid drive, allowing pure electrical, series hybrid and parallel hybrid operation. This hybrid system combines emission free urban driving with accustomed versatile use of a vehicle as far as range and transport capacity are concerned. The operation of the ic-engine may be in a steady state in series as well as in parallel hybrid configuration, thus allowing to maximize the efficiency of the ic-engine and to achieve the best possible emission level. Then modular design of power electronics, control hardware and software is applicable to any type of hybrid system. This paper outlines the considerations which led to the conception of the UHS, and describes its components and the development tools established.
