The invention discloses an energy management method and device for a hybrid vehicle, and the energy management method comprises the steps: obtaining a target adjustment strategy of the hybrid vehicle under a WLTC working condition, setting different values of control parameters of a vehicle engine according to the target adjustment strategy, carrying out the calculation, obtaining an energy consumption data set under different control parameters, and carrying out the calculation of the energy consumption data set under the WLTC working condition. The control parameters in the energy consumption data set do not cause the degradation of the overall endurance mileage of the vehicle, and then the target control parameters of the vehicle engine are determined according to the energy consumption data set, and the target control parameters are the control parameters corresponding to the maximum equivalent all-electric mileage and the minimum engine oil consumption. Therefore, the target control parameter is the control parameter with the lowest energy consumption in all the control parameters, the endurance mileage of the plug-in hybrid power vehicle can reach the maximum when energy management is carried out in the operation process of the hybrid power vehicle according to the target control parameter, and the overall endurance mileage of the plug-in hybrid power vehicle is improved.
本发明公开了一种混动车辆的能量管理方法和装置，能量管理方法通过获取混动车辆在WLTC工况下的目标调整策略，在根据所述目标调整策略将车辆发动机的控制参数设定不同值并进行计算，获得在不同控制参数下的能耗数据集，能耗数据集中的控制参数均不会引起车辆的整体续航里程劣化，再根据所述能耗数据集确定所述车辆发动机的目标控制参数，由于目标控制参数为最大等效全电里程和最小发动机油耗所对应的控制参数，因而目标控制参数是所有控制参数中能耗最低的控制参数，在根据所述目标控制参数在所述混动车辆的运行过程中进行能量管理时，可以使插电式混合动力车辆的续航里程达到最大，因而提高了插电式混合动力车辆的整体续航里程。
