The invention discloses a hybrid electric vehicle energy optimization control method and device, electronic equipment and a storage medium, and relates to the technical field related to vehicles. The method comprises the following steps: calculating a predicted vehicle speed and a predicted acceleration at each predicted moment after a current moment in a predicted time domain according to an actually measured vehicle speed and an actually measured acceleration, and calculating required power corresponding to the predicted vehicle speed according to the predicted vehicle speed and the predicted acceleration; the method comprises the following steps: selecting a battery charge state, a state in which required power is reinforcement learning and a motor torque and/or an engine torque which are corresponding to each prediction moment after the current moment in a prediction time domain as reinforcement learning actions, taking the minimum fuel consumption of the whole vehicle as an optimization target, and performing reinforcement learning to obtain a reinforcement learning result; obtaining an optimal torque distribution sequence corresponding to the minimum fuel consumption in the prediction time domain; and acting the first group of torques in the optimal torque distribution sequence on the vehicle. The requirement of a driver for the whole vehicle driving force can be met, and meanwhile the power source transmission power and the system energy efficiency can be optimized.
