The invention provides a vehicle speed prediction method and device and electronic equipment, and the method comprises the steps: constructing a historical vehicle speed diagram according to historical vehicle speed information, and constructing a driving condition characteristic parameter diagram according to vehicle driving condition characteristic parameters; according to a pre-constructed adaptive redundant feature discarding module, removing corresponding first redundant features and second redundant features in the historical vehicle speed map and the driving condition feature parameter map to obtain target historical vehicle speed features and target driving condition feature parameter features; determining a loss value corresponding to each node according to the target historical vehicle speed characteristic and the target driving condition characteristic parameter characteristic; determining a target attention coefficient according to the loss value; and outputting the predicted vehicle speed through a preset neural network structure according to the target attention coefficient. According to the invention, the prediction accuracy of the whole node is improved, and the real-time accurate prediction of the future driving condition of the extended-range automobile under the small sample condition is realized.
