The invention relates to the field of hybrid electric vehicle energy management, in particular to a hybrid electric vehicle and an energy management control method applying the same. The vehicle is provided with a vehicle control unit for controlling parts such as a motor, an engine and a clutch, and the vehicle control unit analyzes specific input variables to analyze and identify a driving intention of a driver, the driving working condition needing to be executed is judged according to the driving intention, and all assemblies of the vehicle are driven to adopt corresponding energy management control strategies. Specific input variables are analyzed through the vehicle control unit, energy management strategies are adjusted in time, low fuel consumption is achieved under the Fu505 standard cycle working condition, the working efficiency of the gasoline engine is 31.8% or above by adopting different energy management control strategies under different driving working conditions, the purpose of efficient utilization of fuel is achieved, meanwhile, the purpose of recovering most braking energy is achieved, the equivalent fuel consumption rate is reduced, and meanwhile the power performance of the vehicle is met.

    本发明涉及混合动力汽车能量管理领域,更具体地,涉及一种混合动力电动汽车及应用其的能量管理控制方法,汽车设有对电机、发动机、离合器等部件进行控制的整车控制器,整车控制器通过分析特定输入变量,对汽车驾驶员的驾驶意图进行分析识别,根据驾驶意图判断需要执行的行驶工况,驱动所述汽车的各组件采取对应的能量管理控制策略。本发明通过整车控制器分析特定输入变量并及时调整能量管理策略,在Fu505标准循环工况下达到较低的燃油消耗,通过在不同行驶工况下采取不同能量管理控制策略使得汽油机工作效率在31.8%以上,实现燃油高效利用的目的,同时实现对大部分制动能量回收的目标,在降低了等效燃油消耗率的同时,满足车辆的动力性能。
