The invention provides an energy optimization method and system based on equivalent fuel consumption, electronic equipment and a storage medium, and belongs to the technical field of hybrid vehicle energy management. The equivalent fuel consumption of the whole vehicle wheel end in the series connection mode and the parallel connection mode is obtained through a golden section method and a matched wheel end equivalent fuel consumption function in the mode, and the minimum equivalent fuel consumption of the whole vehicle wheel end in the three modes is calculated according to the current required torque of a driver in combination with the equivalent fuel consumption of the whole vehicle wheel end in the pure electric drive mode. The target driving mode of the to-be-optimized vehicle is selected based on the result of the minimum whole vehicle wheel end equivalent fuel consumption and the current state parameter of the to-be-optimized vehicle, the starting and stopping frequency of an engine can be obviously reduced, the NVH performance can be improved, and therefore the problem that a hybrid energy management strategy adopted by a hybrid vehicle in the prior art is solved; the problems that an engine of a hybrid electric vehicle is frequently started and stopped, and the NVH performance is poor exist.

    本发明提供了一种基于等效油耗的能量优化方法、系统、电子设备及存储介质,属于混动车辆能量管理的技术领域,该方法包括获取待优化车辆的当前状态参数,通过黄金分割法及模式下适配的轮端等效油耗函数获取串联模式下以及并联模式下的整车轮端等效油耗,以及结合纯电驱动模式下的整车轮端等效油耗,根据驾驶员当前需求扭矩计算三种模式下的最小整车轮端等效油耗,基于最小整车轮端等效油耗的结果以及待优化车辆的当前状态参数,选择待优化车辆的目标驱动模式,可以明显降低发动机启停频率,提升NVH性能,从而解决现有技术中的混动汽车上所采用的混动能量管理策略,其为了保证电量平衡,往往存在混动汽车的发动机启停频繁、NVH性能不佳的问题。
