The invention relates to the technical field of power transmission of pure electric vehicles, in particular to a topological structure and parameter hierarchical optimization method for an electric drive system of a dual-motor transmission. The method comprises the following steps: determining target design information; according to the target design information, target transmission energy consumption meeting transmission energy consumption conditions is determined; and according to the target transmission energy consumption, target dual-motor parameters and target transmission parameters are determined, so that the topological structure of the target dual-motor transmission electric drive system is determined. By the adoption of the scheme, the obtaining accuracy of the dual-motor transmission electric drive system can be improved.
Description
technical field [0001] The present disclosure relates to the technical field of power transmission of pure electric vehicles, in particular to a topology structure and parameter layered optimization method of a dual-motor transmission electric drive system. Background technique [0002] With the development of science and technology and the continuous improvement of people's living standards, the proportion of individuals owning vehicles continues to increase, and vehicles have become more and more popular household commodities. Among them, carbon emissions from heavy vehicles play an important role in transportation. In order to realize the electrification of heavy-duty vehicles and solve the problem of low power system efficiency caused by the large difference in weight between empty and full load and complex working conditions of heavy-duty vehicles, the electric drive system of dual-motor transmission has received extensive attention. [0003] The topology and parameter...
