摘要：

为了解决因混合动力公交车控制策略开发工况与实际道路工况存在较大差异导致混合动力公交车在实际道路工况行驶下燃油经济性不能达到最佳的问题，在AVL_Cruise建立整车模型，在Matlab/Simlink环境下建立整车控制策略，实车采集郑州市32路公交车实际道路行驶工况并构建这条公交线路的代表性循环工况（ZZDC_32工况）.以此工况为基础，利用基于Isight建立的自动优化平台对整车控制策略的5个关键参数进行全局优化，通过半实物试验对基于ZZDC_32工况优化后的整车控制策略进行验证，结果表明：混合动力公交车百公里燃油消耗比实际燃油消耗降低了5.8%.
Abstract:

Vehicle model and control strategy model were established in AVL_Cruise and Matlab/Simlink respectively in order to solve the problem that the hybrid electric bus was not able to achieve the best fuel economy under the actual road driving cycle due to the large difference between the development cycle (China_Urban drive cycle) of the hybrid electric bus control strategy and the actual road driving cycle. The actual road driving cycle of Zhengzhou 32 bus was collected, which were used to synthesis the representative circulation condition of the 32 bus line. Under ZZDC_32 drive cycle, five key parameters(upper limit of SOC battery, discharge coefficient of power battery, engine upper and lower limit correction factor and electric control clutch combined with speed) of the vehicle control strategy were optimized by using the automatic optimization platform based on Isight.The vehicle control strategy based on the ZZDC_32 condition was verified by the semi-physical experiment. The fuel consumption reduces5.8% compared with the actual fuel consumption of hybrid electric bus.
