Vehicle Energy Management Optimization through Digital Maps and Connectivity. Karbowski, D.; Sokolov, V.; and Rousseau, A. In pages 10.
abstract   bibtex   
There is an opportunity for using digital maps with real-time updates to improve the energy management of vehicles. In this paper, we present research on how this can be achieved in the particular case of plug-in hybrid electric vehicles. With perfect knowledge of the trip ahead, it is possible to find the optimal control of the vehicle. Digital maps, however, provide only averaged information about the future itinerary, such as locations of stops, types of intersection, and average speeds. First, we demonstrate how we can generate naturalistic speed profiles for a given itinerary. We do so by augmenting the information from digital maps by actual recorded speeds from a travel survey and Markov chains. Second, we detail how these speed profiles can be used for control optimization. We use the Pontryagin minimum principle to optimally tune the vehicle energy management and then evaluate the actual fuel savings using the Autonomie simulation tool.
