摘　　要：提出了基于一种新型的单电机、双离合器式强混合动力结构的车辆分层控制系统方案,制定了整车能量管理策略,并研究了车辆行进中启动发动机过程的动态协调控制方法。通过自行开发的前向仿真系统对能量管理策略进行了验证,在NEDC循环工况下等效百公里油耗降低了34%。同时通过动态台架试验,对车辆行进中启动发动机的动态协调控制策略进行了验证。A layered control system was established based on a newly developed full hybrid vehicle with the structure of single motor and double clutches, energy management strategy was instituted and the concerted control strategy for dynamic process of engine start while driving was studied. The energy management strategy was validated by a developed forward simulation model, a fuel consumption reduction of 34% in the NEDC driving cycle is achieved. A dynamic test bench was built to confirm the concerted control strategy for dynamic process of engine start while driving.
