摘要
为某一混合动力城市客车开发了整车控制系统,包括能量管理策略和动力协调控制。能量管理策略根据对客车工作模式的划分和分析,确定各个模式相应的控制策略;动力协调控制则以主驱动电机转矩作为补偿,实现了AMT换挡的动力不中断。同时,基于自动代码生成技术开发了整车控制器(HCU)软件。实车试验表明,所开发的整车控制系统使混合动力城市客车经济性提高了约26%,动力性改善了约17%,排放也有所降低。
The vehicle control system（VCS） for a hybrid electric city bus is developed,including energy management strategy（EMS） and power coordination control（PCC）.Based on the division and analysis of bus operation modes,the EMS determines the corresponding control strategy for each operation mode;while PCC uses the torque of the driving motor as compensation to realize AMT shifting without power interruption.In addition,the software of hybrid control unit（HCU） is developed using automatic code generation technology.The results of real vehicle test show that with the VCS developed,the fuel economy and power performance of the hybrid electric city bus are enhanced by around 26% and 17% respectively with emissions also improved.
