【 摘 要 】

Although recent studies of connected and automated vehicles (CAVs) have begun to explore the potentialenergy and greenhouse gas (GHG) emission impacts from an operational perspective, little is knownabout how the full life cycle of the vehicle will be impacted. We report the results of a life cycleassessment (LCA) of Level 4 CAV sensing and computing subsystems integrated into internalcombustion engine vehicle (ICEV) and battery electric vehicle (BEV) platforms. The results indicate thatCAV subsystems could increase vehicle primary energy use and GHG emissions by 3−20% due toincreases in power consumption, weight, drag, and data transmission. However, when potentialoperational effects of CAVs are included (e.g., eco-driving, platooning, and intersection connectivity), thenet result is up to a 9% reduction in energy and GHG emissions in the base case. Overall, this studyhighlights opportunities where CAVs can improve net energy and environmental performance.
