摘 要:
为混合动力汽车建立了分层控制系统，并用最优控制和模糊逻辑等方法进行了控制策略的研究。并联混舍动力汽车控制系统包括能量管理策略和能量管理策略的实现两个层面．能量管理策略层根据驾驶员输入和车辆状态确定动力传动系统各部件目标工作状态；能量管理策略实现层以行驶平顺性和离合器磨损为目标对发动机、电机、离合器和变速系统进行协调控制。仿真及试验结果表明，分层控制系统能够实现整车控制要求的功能以及整车的燃油经济性指标、行驶平顺性和离合器磨损指标等设计目标。[著者文摘]

Abstract:
A hierarchical control system was proposed for the hybrid electric vehicles （HEVs）, and the methods of optimal control theory and fuzzy logic control were utilized to design the control strategy. The energy management strategy of the control system determined the target statuses of powertrain components according to the driver＇s input and the vehicle state. The engine, motor, clutch and transmission were controlled by the implementation layer of the control system to improve the driving smoothness and minimize the clutch abrasion. The simulation and fields tests results showed the validation of the proposed control system.[著者文摘]
Key words:
parallel hybrid electric vehicle, automatic mechanical transmission, fuel economy, driving smoothness, clutch abrasion
