The invention relates to the technical field of vehicles, in particular to a vehicle speed control method and device, a vehicle and a storage medium, and the method comprises the steps: optimizing the preset weight and threshold of a BP neural network through a sparrow search algorithm under the condition that the vehicle is detected to be in a vehicle speed control working condition, and obtaining the optimized weight and threshold; and training a BP neural network according to the optimized weight and threshold, and obtaining control parameters of a PID controller based on the trained BP neural network so as to output a speed compensation amount and/or an acceleration compensation amount of the vehicle, thereby controlling the vehicle speed according to an obtained control instruction. According to the embodiment of the invention, the weight and the threshold value of the BP neural network can be optimized by using the sparrow search algorithm, the BP neural network is trained, and the control parameters of the PID controller are obtained by using the trained BP neural network, so that the vehicle speed is controlled according to the obtained control instruction, and the safety and the stability of vehicle speed control are effectively improved.
