增程式电动公交客车控制策略研究

摘要

With a serial extended-range electric bus as research object, this paper analyzes effect of single-point thermostat control strategy, power-following control strategy and fuzzy logic control strategy adopted in the battery power sustaining stage, and concludes that single-point thermostat control strategy is suitable for extended-range electric vehicle (EREV) in power sustaining stage. Meanwhile an equivalent fuel consumption based on fuel-electric equivalence factor is proposed to evaluate fuel economy of EREV. According to 100-200 km per day, this extended-range electric bus can achieve 40%~60% fuel economy improvement on conventional city buses.%以某串联式结构的增程式电动公交客车为对象,针对电池电量维持阶段采用的单点恒温器控制策略、功率跟随控制策略、模糊逻辑控制策略效果进行分析,得出了增程式电动汽车电量维持阶段适合采用单点恒温器控制策略的结论.同时,提出了基于油电等价因子的等效百公里燃油消耗以用于评价增程式电动汽车的燃油经济性.按城市公交客车每天运行100～200 km计算,该增程式电动公交客车比传统柴油公交客车节油40％～60％.
