Comparison of different driving cycles control effects of an extended-range electric bus

In order to improve the economy in actual driving cycle of the electric bus, an extended-range electric vehicle (EREV) powertrain system evaluation method based on the characteristics of the driving cycle is proposed. The powertrain simulation model is established. This paper uses the energy management strategies of CD-CS and Blended to simulate and analyze the EREV in the driving cycles of Chinese city and Zhuzhou of Hunan province of China. The simulation results show that the EREV economies are different in different driving cycles. Compared with the conventional diesel bus, if not considering the power consumption, the fuel-saving ratio can reach above 30% in both city driving cycles.
