摘要
在选取循环工况和制定整车基本控制策略的基础上,对天然气混合动力城市客车的动力系统进行了设计与开发,包括其系统结构布置方案的确定,发动机、电机、电池和传动系统等的参数设计和匹配。动力系统的仿真结果表明设计达到了要求。样车试制完成以后,进行目标循环工况下的实际道路试验,结果表明:与同级天然气城市客车相比,最大爬坡度增加了28%,0～50km加速时间减少1.8s以上,中国典型城市公交循环工况下的节气率达到22%。
The design of propulsion system for CNG-electric hybrid city-bus is introduced based on the selection of driving cycle and the establishment of control strategy. Making program of powertrain＇ s configuration is included as well as parameters＇ selection and matching of components such as engine, motor, battery and transmission. The simulation results show that the design meets the requirements. The components of the propulsion system are integrated together, and then they are installed into the sample city-bus. The roadway test has been done under the target driving cycle. Compared with the peer CNG city-bus, there are 28% increasing in the largest climb degree and the acceleration time of 0-50 km is reduced more than 1.8 s, and the fuel saving rate achieves to 22 % under the typical city-bus driving cycle of China.
