【Abstract】 Two energy sources drive and electro-mechanical brake are the generic technologies of the powertrains for various types of plug-in hybrid electric vehicles,and the flexibility of the driving energy forms and the power flows highlight the necessity for vehicle energy management. To clarify the keyissue of vehicle energy management,the operation modes and the corresponding power flows were analyzed according to the powertrain architectures for three kinds of typical forms. Based on whether the control variables of the energy splitting problem are the relating calculation results of the optimization problem,the existing strategies were classified into two groups consist of rule-based and optimizationbased control. The main contributions for most of them were reviewed,and its optimization effect and algorithm complexity were compared. Moreover,the simulation was carried out for a part of the strategies to test its performance. On the basis of the above,the challenges of the energy management for plug-in hybrid electric vehicles were summarized for the future research.更多还原
