The invention relates to the field of trajectory tracking, in particular to a trajectory tracking method and device for an unmanned vehicle, and the method comprises the steps: obtaining a to-be-tracked trajectory of the unmanned vehicle, and enabling the to-be-tracked trajectory to be provided with a plurality of identification segments; obtaining the trajectory complexity of the trajectory corresponding to any identification segment; acquiring real-time position information of the unmanned vehicle, and determining a distance difference value between the current position and the identification section; adjusting the transverse deviation range of the unmanned vehicle and the to-be-tracked trajectory according to the distance difference and the trajectory complexity; and track evaluation is carried out on the identification section according to the adjusted transverse deviation range. The transverse deviation range of the unmanned vehicle and the to-be-tracked trajectory is adjusted according to the distance difference and the trajectory complexity, so that an adjustment strategy is determined for the position of the unmanned vehicle, the transverse deviation range of the to-be-tracked trajectory conforms to expectation, and the tracking control accuracy of the unmanned vehicle is improved.
