The embodiment of the invention discloses a driving intention prediction method and device and a vehicle. The method comprises the steps of obtaining a target obstacle of a vehicle; constructing a speed combined potential field corresponding to the target obstacle based on the distance between each of the remaining obstacles in the current road and the target obstacle; obtaining a transformation path of the target obstacle based on the speed combined potential field and a predicted driving track of the target obstacle; obtaining a plurality of differential entropies of the target obstacle based on the transformation path and a plurality of reference intention paths corresponding to the target obstacle; and obtaining a driving intention of the target obstacle based on a pre-trained hidden Markov model and the plurality of differential entropies. Through the above mode, the accuracy of predicting the driving intention of the target obstacle can be improved.
