The increase of energy efficiency of vehicles in the course of rising energy costs and the limited range of electric vehicles can be realized with ecological driver assistance systems. Based on preview information these systems can assist the driver in providing energy efficient driving and operating strategies. But, many of these systems directly focus on specific functional approaches and do not consider a comprehensive system architecture. Thus, functional extensions and adoptions to other vehicle and propulsion concepts are hereby complicated.

In this paper a generic system architecture is introduced which represents a framework for present and future for assistance systems for ecological optimization. The framework provides hereby the overview of the necessary core modules and the interfaces between them. The innovative aspect of the introduced framework is the modularization in a vehicle independent optimization module and a vehicle dependent energy conversion model. This approach promotes a vehicle independent and efficient system development. The system architecture aims to provide a basis for assistance systems that are robust towards functional extensions and adoptions to other vehicle and propulsion concepts.

In an exemplary use case the application of the generic system architecture is demonstrated and the portability is discussed.
