The invention provides a vehicle track prediction method and device, a chip, a terminal and computer equipment, and relates to the technical field of non-electrical variable control or adjustment systems. The method comprises the following steps: determining a relative coordinate system relative to a vehicle body coordinate system at a starting moment according to geodetic coordinates of a vehicle at different driving moments; obtaining the transverse displacement, the longitudinal speed and the longitudinal acceleration of the vehicle under the relative coordinate system at different driving moments, and generating an observation state sequence according to the transverse displacement, the longitudinal speed and the longitudinal acceleration; based on the observation state sequence and behavior recognition models corresponding to different driving behaviors, the driving behaviors of the vehicle are recognized; based on the observation state sequence and a preset polynomial, track curve sets of different driving behaviors are generated, and in the track curve sets of different driving behaviors, a target track curve set corresponding to the recognized driving behaviors of the vehicle is determined; and determining the trajectory curve of the vehicle in the target trajectory curve set according to the observation state sequence.
