State-of-the-art and Development Trends of Energy Management Strategies for Intelligent and Connected New Energy Vehicles：A Review 2019-01-1216
Intelligent and connected vehicle (ICV) and new energy vehicle (NEV) will be two important directions of the automotive technology in the future, and the coordinated development of these two directions reflects relevantly the higher requirements put forward by nowadays society and people. Through the use of intelligent and connected technology, new energy vehicles can exchange various traffic information data with the outside world (e.g. other running vehicles, road infrastructure, internet, etc.) in real time, which is so-called Vehicle to Everything (V2X). Based on the further analysis of the mutual traffic information, the vehicles can identify the current driving conditions and predict the future driving conditions effectively, which can realize the real time optimization of energy management strategy of the vehicle’s powertrain system, so as to meet the driving requirements of vehicles under different driving conditions. This will not only greatly improve the fuel economy of the vehicles, but also ease the traffic congestion situation effectively. A review on the application results of intelligent and connected technology (ICT) in new energy vehicles (mainly hybrid vehicles) in recent years are given, the research circumstances of ICT and intelligent and connected new energy vehicles’ energy management strategies are analyzed and summarized in detail. Based on these comprehensive analyses, the development direction of researches on the coordinated development of ICT and NEV are illustrated. The final conclusion will provide theoretical basis for the development of intelligent transportation system (ITS) and internet of vehicles technology, and also make a contribution to the development of clean transportation and environmental protection.
