Abstract:

Dynamic traffic information is a fantastic way to keep vehicles and drivers informed while on the road. The literature on dynamic traffic information for conventional automobiles is extensive. This paper treats the question of how dynamic traffic information for EVs should be represented and which additional requirements for EVs are necessary.  A common approach is to broadcast an average speed value per road segment. Usually, this is sufficient to calculate an approximate travel time on a given route. For electric vehicles, where the overall range is limited, it is crucial to know the ongoing traffic situation best in order not to drain the battery. To this end, knowledge on the estimated energy consumption is significantly more relevant than knowledge on the average travel time. This paper aims to provide a literature survey of current energy consumption models and energy-efficient routing algorithms, and adapts current dynamic traffic information towards electric driving. A real-world field study from Germany has been evaluated and serves as a basis for energy consumption analyses.
