摘要：AbstractThe development of connected vehicle technology presents opportunity for hybrid electric vehicle (HEV) to further improve its energy efficiency. Within this horizon, the energy management strategy (EMS) considering connective information is an enabling technology. In this paper, a hierarchical EMS combining velocity planning and power split management is proposed for HEV under connective scenarios. Particularly, the driving route is separated into several segments, and the length of single segment is adaptively adjusted according to the possibility pre-judgment for preceding vehicle crossing the upcoming intersection. Furthermore, the velocity trajectory is optimized by incorporating the preceding vehicle pre-judgment and traffic information with dynamic programming. The equivalent consumption minimization strategy (ECMS) is used to realize the power split optimal distribution in lower level. Finally, the simulation results demonstrate the effectiveness of proposed method.
