The invention relates to a vehicle speed prediction method, a vehicle speed prediction device, a vehicle control device and a storage medium. The method comprises the following steps: obtaining a current position and a current vehicle speed of a vehicle, congestion condition information of a current road and predicted duration; searching a vehicle speed corresponding to the current position basedon a pre-established typical working condition according to the current position in order to obtain a standard vehicle speed; calculating a difference value between the standard vehicle speed and thecurrent vehicle speed to obtain a vehicle speed difference; inputting the vehicle speed difference, the congestion condition information, the current vehicle speed and the predicted duration into a pre-trained weighting coefficient prediction model to obtain a weighting coefficient; predicating the vehicle speed of the vehicle after the predicted duration according to the current position, the current vehicle speed and the predicted duration in order to obtain a preliminary predicted vehicle speed; and correcting the preliminary predicted vehicle speed through the weighting coefficient to obtain a target predicted vehicle speed. The vehicle speed predicted by the vehicle speed prediction method provided by the invention is high in accuracy.
