This paper established a simulation calculation model for CO2 emission of heavy-duty vehicles based on the power transmission chain of vehicle,and investigated the degree of influence of key component parameters on the CO2 emission of vehicle.Taking four driving cycles of three heavy-duty vehicles as research samples,the simulation calculation scheme of eight component parameters was designed,the characterization function of the degree of influence was formulated for evaluation,and the factors affecting the CO2 emission test results were summarized through experiments,which will provide a reference for the revision of the relevant standards.
