摘要：AbstractThe energy consumption of plug-in hybrid electric vehicles (PHEV) is influenced by driving cycles. In this paper, the influence of driving cycles has been analyzed for the PHEV energy consumption, which can provide a theoretical basis for the energy management strategy development. The K-means clustering method is used to divide driving cycles into different patterns. The energy consumption mathematical models of the PHEV powertrain are built based on the efficiency models of powertrain system. Then, the simulation models of energy consumption for PHEV are built based on MATLAB/Simulink software, and the simulation has been conducted using the CD-CS control strategy. Finally, the influence of driving cycles on energy consumption is obtained. The results show that taking full use of electrical energy is the more important to improve energy efficiency for PHEV, comparing with the traditional control of PHEV is only to enhance engine operating efficiency.
