Abstract

The invention relates to a selection method of a plug-in hybrid power system configuration, and in the selection method of the plug-in hybrid power system configuration, through screening based on ownresearch and development resources, a selection range of the plug-in hybrid power system configuration can be reduced effectively. By combining a global optimization control strategy based on dynamicplanning with component parameter optimization based on an orthogonal test design method, a nested loop formed by combination of the control strategy optimization and the component parameter optimization is built, and by taking a vehicle power performance design target, vehicle cabin inner space size and emission performance as constrain conditions and taking the lowest cost as a target, selecting the configuration with the lowest cost under a condition of united optimization of the control strategy and component parameters is realized, calculation load is low, and the method is simple and convenient to operate.

Description

technical field [0001] The present application relates to the technical field of plug-in hybrid electric vehicles, in particular to a method for selecting a configuration of a plug-in hybrid electric vehicle. 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. The parameter matching of each component and the formula...
