The invention provides an energy management method and system, computer equipment and a readable storage medium, and the method comprises the steps: obtaining traffic information and road information, and calculating a driving strategy of a vehicle; constructing a first constraint condition according to a driving strategy, and performing speed planning on the vehicle to obtain a corresponding speed trajectory optimal curve; and speed tracking based on energy consumption optimization is carried out on the vehicle, so that the vehicle tracks the speed trajectory optimal curve in the predicted time domain, and the motor energy consumption of the vehicle is controlled. According to the invention, external information such as traffic information, road information and the like is introduced and is combined with the bottom layer control of the vehicle power transmission system, so that the vehicle can adapt to various road conditions, and the energy consumption of the vehicle can be managed in real time, so that the energy-saving potential of the vehicle is improved; the problem of non-car-following speed trajectory optimization in a low-density traffic scene is solved.

    本发明提供了一种能量管理方法、系统、计算机设备及可读存储介质,该能量管理方法包括获取交通信息和道路信息,计算出车辆的行车策略;根据行车策略构建第一约束条件,对所述车辆进行速度规划,以得到对应的速度轨迹最优曲线;对车辆进行基于能耗优化的速度跟踪,以使车辆在预测时域内跟踪速度轨迹最优曲线,并控制车辆的电机能耗。通过本申请,通过引入外界信息比如交通信息、道路信息等并与车辆动力传动系统底层控制相结合,使得车辆能够适应多种路况,且还能够实时对车辆能耗进行管理,以提升车辆的节能潜力,解决了低密度交通情景中的非跟车速度轨迹最优问题。
