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
