Energetic Impact of Urban Cooperative Driving on the Example of Intersections

The use of automated driving and connectivity can be an additional lever to reduce fuel and energy consumption in real driving and has an impact on the drive system and its dimensioning as well. In this paper we are addressing the impact urban cooperative driving on the energy consumption of electric vehicles and investigate further the impact of the drive system and their layout. To this end, a concept study is being conducted for a D-segment vehicle and two battery electric powertrains. In order to evaluate the impact, defined driving profiles from a connected intersection are used for simulation. Based upon the results the overall energetic impact of different intersection approaching strategies as well as the drive system impact are discussed. It showed that a cooperative intersection scenario leads to an energy reduction of 14% and first come first serve scenarios to an energy reduction of 7%.
