The invention relates to a plug-in hybrid electric system configuration selecting method based on limiting energy saving rate assessment. A benchmarking vehicle is determined by selecting a sample electric system in a sample vehicle, and thus, an energy saving analysis benchmarking target is established. The energy saving mechanism is viewed fundamentally by seeing through clearly energy flow conditions of plug-in hybrid electric systems corresponding to different plug-in hybrid electric system configurations. An energy saving rate computational formula is deduced through the energy conservation criterion, a limiting energy saving rate is computed by adopting limiting conditions, the maximum energy saving potential of the plug-in hybrid electric system relative to a sample electric systemcan be primarily mastered, and the computational amount is obviously reduced. In addition, the method can be mastered by automobile enterprises, and the energy saving potential of the plug-in hybrid electric system configuration can be easily found out by applying the method, so that new research and development strategies are formulated.
Description
technical field [0001] The present application relates to the technical field of plug-in hybrid electric vehicles, in particular to a configuration selection method of a plug-in hybrid electric power system based on the evaluation of the limit energy-saving rate. Background technique [0002] Plug-in hybrid electric vehicle (PHEV, Plug-in Hybrid Electric Vehicle) can effectively reduce fuel consumption and reduce pollutant emissions. It has been researched and developed by major manufacturers around the world, and its market share is also increasing rapidly year by year. The research and development of PHEV requires R & D manufacturers to have both traditional internal combustion engine mechanical transmission technology and electric transmission technology, which is difficult and requires a long development cycle. [0003] PHEV has various plug-in hybrid system configurations, and the plug-in hybrid system configuration represents the overall technical framework of PHEV. T...
