According to the method, the optimal planning of the electric quantity of the intelligent networked plug-in hybrid power bus is realized, the problem of deterioration of vehicle energy consumption caused by unreasonable electric quantity distribution is solved, and the method has great significance in deeply excavating the energy-saving and emission-reducing potential of a plug-in hybrid power system. And the method has great theoretical and practical values for promoting green and sustainable development of urban public transportation.
