The invention relates to an energy management method for a hybrid vehicle, belongs to the field of automatic driving, and is used for solving the problems of low response speed when a fuel cell is adopted, difficulty in directly coping with complex and changeable traffic scenes, low cost and the like due to the lack of consideration on actual driving requirements and neglecting the influence of other traffic factors in the current automatic driving field. When power batteries are connected in parallel, different power sources have different output characteristics, and most of current mainstream energy management strategies have the problems of poor real-time performance and low stability due to a complex calculation process. The method comprises the steps that the average speed on a driving route of the hybrid power vehicle serves as a reference driving working condition of the vehicle in a future period of time; the reference driving power of the hybrid power vehicle is obtained through the reference driving working condition; and performing wavelet transformation on the reference power, and obtaining the optimal distribution power output of the power cell and the fuel cell by enabling the wavelet transformation objective function W to obtain the minimum value.

    本发明涉及一种混合动力车辆能量管理方法,属于自动驾驶领域,用于解决目前自动驾驶领域缺乏对实际驾驶需求考虑且忽略了其他交通因素的影响,在采用燃料电池时响应速度慢、难以直接应对复杂多变的交通场景,而通过并联动力电池时,不同动力源具有不同的输出特性,当前主流的能量管理策略大多因复杂的计算过程具有实时性差、稳定性低的问题。本案方法步骤包括:将混合动力车辆行驶路线上的平均速度作为车辆未来一段时间的基准行驶工况;利用基准行驶工况,得到混合动力车辆行驶的基准功率;将基准功率进行小波变换,通过使小波变换目标函数W取得最小值,获得动力电池和燃料电池的最优分配功率输出。
