摘要
以某增程式天然气混合动力公交车为研究对象,在全电力集中控制策略基础上,开发了基于电池SOC的预设转速控制策略和基于电池SOC和车速的预设转速控制策略,并在AVL Cruise中建立了整车模型及相应控制算法模块,在中国典型城市公交循环工况下进行了仿真分析。仿真结果表明,所开发的控制策略能够有效改善公交车在电荷保持阶段的气耗和电量消耗及电量保持阶段下的综合能耗。
Based on all-electric-range-focused strategy, the default speed control strategy based on battery SOC and default speed control strategy based on combination of battery SOC and vehicle speed are developed, then the vehicle simulation model with corresponding control algorithm modules is built with AVL Cruise software. The above model is simulated under China typical city bus drive cycle. The simulation results show that the developed control strategies can effectively improve the CNG consumption rate during the Charge Sustaining （CS） phase and also the comprehensive energy consumption during both Charge Depleting （CD） and CS phase.
