Motivation

Basic idea behind the eco2DAS project

By enabling a systematic network the ecological and economical gefficiency of a vehicle can be

increased

Drawback of already existing solutionsy g Most of the solutions are developed for certain drive train and driver

assistance concepts

Missing interface definitions

Approaches are not transferable to other vehicle/assistance concepts
