Abstract：Providing real-time road condition，slope and curvature information in time and accurately can effectively help the plug-in hybrid vehicle choose the most appropriate power system operation mode and energy recovery intensity，and optimize the system efficiency of the whole journey to the maximum extent. The intelligent energy management system proposed in this paper is just based on the internet map to provide real-time effective map information for the vehicle control system and improve the fuel economy of the vehicle. This paper also proposes a method to realize route matching in the cloud road network，so that the slope and curvature information matching the designated route will be issued by the cloud. This scheme can effectively solve the problem of lacking slope and curvature in the vehicle map module，and also solve the freshness problem of slope and curvature data. The research results can provide reference for related application and research.
