The development of hybrid vehicle technology is most actual and important task of modern automotive industry. The hybrid control software is a key element of this technology. At present, almost all the OEMs are developing hybrid vehicles with various topologies (configuration of hybrid drive train), various used hybrid components (electric motor(s), battery, ), various applications (passenger car, taxi, city bus, truck, ) for various markets, etc. As the literature and patent search shows, this variability is reflected in many different variants of hybrid control software architecture and implementation. Such an approach individual software for each new hybrid variant, - leads to enormous increase of development costs and quite limited reusability of the control software. On the other hand, the number of basic hybrid functionalities remains limited. By use of an appropriate approach, for instance, the one based on synthetic driving cycle and corresponding generalized vehicle driving maneuvers, it is possible to describe the hybrid functionalities systematically and to find a common basis for different hybrid variants. This paves the way for common software architecture with software components having the same structure and functions that can to a large extent be used for different hybrid variants. The aim of the present project is to develop such generic hybrid control software by using modern software development processes. The most important attributes of this generic software shall be high reusability of software components and its real scalability i.e. the software shall be easily extendable to accommodate new or modified hybrid functions, new advanced control algorithms, and ability to deal not only with various hybrid topologies, but also with various interference configurations.
