Parametric optimization is an important step for any mechanical system design, including the development and design of a hybrid
electric bus. To obtain an optimized parameter grouping of the EQ6110HEV hybrid electric bus for best fuel economy, an orthogonal
experiment design method is applied to the parameter optimization process of the EQ6110HEV hybrid prolusion system. This paper
proposes two orthogonal experiment methods; the basically orthogonal experiment method and the synthetically orthogonal experiment
method. By this means, the development time and the testing costs are reduced, and the impact of factors and their optimal
levels are obtained by a range analysis of the experiment results. The results show that the fuel economy of the optimized
parameter grouping is improved by 4.1 percent for the four-stage urban driving cycle in China and by 8.7 percent for the Wuhan
urban driving cycle of public buses in China, in comparison with that of the parameter grouping of the current configuration. 相似文献

Series-parallel PHEV city buses combine the advantages of series and parallel configurations and have been used in China. However, the design and energy management of series-parallel PHEV city buses based on Chinese driving conditions still need to be investigated. In this paper, an equivalent consumption minimization strategy is provided to optimize energy management for series-parallel PHEV city buses, and the process of the equivalent consumption minimization strategy for series-parallel is presented in this paper. Compared with the validated rule-based energy control strategy, ECMS shows a fuel economy improvement of 8.2 % in the CBCD (Chinese Bus Driving Cycle). Based on the optimal energy management, a design for a generator motor in the series-parallel configuration has been processed. The fuel consumption has been shown to decrease, with an increase in generator power, because the system with the higher generator power can work at a higher efficiency in the series mode and operate the engine in the high efficiency area in the parallel mode. Besides, in terms of costof- ownership for a PHEV bus for lifetime of 8 years, although the high generator power will lead to high purchase cost for series-parallel PHEV bus, a series-parallel PHEV city bus with a generator of 100 kW maximum power will still show small advantage in cost-of-ownership, based on current motor price and natural gas price. 相似文献
