The invention discloses a multi-power-source vehicle energy management strategy determination method, system and device, and relates to the field of vehicle control, and the method comprises the steps: predicting the vehicle speed of the next moment through a speed prediction model based on a long short-term memory network according to the current vehicle speed; the current vehicle speed, the vehicle speed at the next moment, the vehicle battery state and the required torque at the current moment serve as observation variables; according to the observation variables, a motion signal prediction model based on a soft actor-commentator network is adopted to determine continuous motion signals; according to the continuous action signal, a gear mode is determined by adopting a Gumbel-Softmax model; and controlling the vehicle according to the determined gear mode. According to the method, the working condition of the next state can be predicted, and the rotating speed and the mode of the engine of the vehicle are controlled at the same time according to the working conditions of the current state and the next state.

    本发明公开一种多动力源车辆能量管理策略确定方法、系统及设备,涉及车辆控制领域,该方法包括根据当前的车速,利用基于长短期记忆网络的速度预测模型,预测下一时刻的车速;将当前的车速、下一时刻的车速、车辆电池状态和当前时刻的需求扭矩作为观察变量;根据观察变量,采用基于软演员‑评论家网络的动作信号预测模型,确定连续动作信号;根据连续动作信号,采用Gumbel‑Softmax模型确定档位模式;根据确定的档位模式进行车辆控制。本发明能够实现对下一状态工况做出预测,并根据当前和下一状态的工况对车辆的发动机转速和模式同时做出控制。
