The invention provides a tandem type hybrid electric vehicle energy management method and device and a hybrid electric vehicle for a tandem type hybrid power system. By means of the characteristics ofa power battery, an engine can be promoted to avoid a high-oil-consumption and high-emission area and only work in an efficient working area; and efficient cleaning of the hybrid power assembly is realized under the condition of considering power, economy and emission performance. The method comprises the following steps: collecting the whole vehicle demand power of a vehicle at the current moment and the state of charge (SOC) of a battery; comparing the required power of the whole vehicle with each power in an engine working MAP to obtain a first comparison result; comparing the SOC of the battery with a state of charge upper limit value SOC_high and a state of charge lower limit value SOC_low corresponding to the economic working area of the engine to obtain a second comparison result;according to the first comparison result and the second comparison result, dividing the working modes of the power assembly of the vehicle; and controlling each power assembly of the vehicle to work according to the divided working modes.
本发明专利针对串联式混合动力系统提出了一种串联式混合动力汽车能量管理方法、装置及混合动力汽车,借助动力电池的特性可促使发动机避免高油耗、高排放区域而只工作在高效工作区域,在兼顾动力、经济与排放性能条件下实现混和动力总成高效清洁化。该方法包括:采集车辆当前时刻的整车需求功率和电池的荷电状态SOC;将整车需求功率与发动机工作MAP图中的各功率进行比对,得到第一比对结果;将电池的荷电状态SOC与发动机经济工作区域对应的荷电状态上限值SOC_high和荷电状态下限值SOC_low进行比对,得到第二比对结果;根据第一比对结果和第二比对结果,对车辆的动力总成的工作模式进行划分;控制车辆的各动力总成按照所划分的工作模式进行工作。
