Hybrid electric vehicles (HEVs) have been widely developed in recent years owing to their advantages such as environmental protection, low noise and energy saving. The signal intersections are an important part of urban roads, where the traffic congestion is easy to occur when the road vehicle density is high, thus reducing the efficiency of the entire road network and affecting the fuel economy of vehicles. With the development of new technologies such as intelligent transport systems, the problem of HEV energy management considering the road traffic information is becoming a research hotspot. The research results of speed planning and energy management strategy (EMS) for HEVs considering road slopes and combination of single and mixed vehicles at signal intersections are introduced, the existing methods of speed trajectory optimization and EMS based on fusing the road traffic information which are proposed by scholars both at home and abroad are summarized, and the development of EMS considering the traffic information is also discussed.
