摘　　要：对一辆12m混合动力城市客车,分别在高原和平原地区进行了相同循环行驶工况的性能比对试验,以分析客车在不同运行条件下燃油经济性和电机助力能量的变化。结果表明:高原环境对客车的燃油经济性有明显影响,每循环燃油消耗量比平原地区平均增加5.62%;每循环燃油消耗量受电机助力能量影响较大,受起步方式的影响较小;制动回收能量和电机助力能量基本不受高原环境的影响,电机助力能量波动较大主要与动力电池的起始SOC值有关。A performance comparison test on a 12-meter hybrid electric city bus is conducted in both plat- eau and plain regions respectively with the same driving cycle to analyze its variation in fuel economy and＂ motor boost energy under different operation conditions. The results show that the plateau environment has significant effects on the fuel economy of bus with the fuel consumption per cycle increases by 5.62% on average compared with that in plain region. The fuel consumption per cycle is influenced more by motor boost energy and less by start- ing mode. The plateau environment basically has no effects on regenerative braking energy, and the apparent fluctu- ations of motor boost energy are primarily related to the initial SOC of batteries.
