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.
