Digital maps, connectivity and electric vehicles -enhancing the EV/PHEV ownership experience

Abstract

Electrification of the automobile is a growing trend and will create both challenges and opportunities for the vehicle manufacturer, road network infrastructure and driver. In addition to innovative fundamental battery and power transfer technologies, electric vehicles will integrate unique driver interfaces, road intelligence, traffic awareness and wireless data communication to provide a complete support system. This networked vehicle will improve efficiency, increase cruising range and contribute to the overall driving enjoyment of an electric or plug-in hybrid-electric vehicle. Through tailored applications created by content and service providers the driver will identify the most efficient travel routes, learn efficient driving behaviors, avoid energy-wasting situations, locate charging stations and have confidence in reaching a destination and returning home. Using map-based predictive technology, vehicle power controls will become more efficient through knowledge of road terrain, traffic controls and regeneration opportunities. In fact, research demonstrates that connected hybrid electric vehicles using digital map information can demonstrate energy savings on the order of 25%. © 2010 SAE International.
