The invention discloses a plug-in hybrid electric vehicle energy management system and method based on road section information electric quantity distribution. The plug-in hybrid electric vehicle energy management system comprises an off-line part which is used for collecting driving data, processing and classifying the data and synthesizing a new working condition. A support vector machine is trained for data to identify working conditions, DP algorithm operation is carried out on the combined new working conditions, the result of the DP algorithm is processed, the BP network is trained to obtain the electric quantity distribution relation of each working condition, the other part is offline optimization of an ECMS algorithm, and offline optimization of equivalent factors is carried out on each type of working conditions. And the online part is used for obtaining an electric quantity distribution relation through a BP neural network according to the information of each road section and the identification information obtained by the traffic information obtaining module, then planning an SOC, and then selecting an equivalent factor according to a working condition and an SOC planning track and carrying out operation. According to the method, electric quantity distribution and equivalent factor selection are more reasonable, and the fuel economy of the plug-in hybrid electric vehicle can be better improved.
