The invention provides a vehicle behavior prediction method based on a two-channel Gaussian mixture hidden Markov model. The vehicle behavior prediction method can be applied to the technical field of automatic driving and the technical field of vehicle auxiliary driving. The method comprises the following steps: acquiring driving environment data of a driving vehicle in a preset time period; determining motion characteristics of the target vehicle according to the driving environment data; according to a motion feature sequence formed by the motion features, the probability of the motion feature sequence is determined through a two-channel Gaussian mixture hidden Markov model, and the motion feature sequence comprises a first motion feature sequence and a second motion feature sequence; the two-channel Gaussian mixture hidden Markov model obtains the probability of the motion feature sequence according to probability recursion of motion features in the motion feature sequence; and predicting the motion behavior of the target vehicle according to the probability of the motion feature sequence. The invention further provides a vehicle behavior prediction device based on the two-channel Gaussian mixture hidden Markov model and electronic equipment.
