Abstract

The invention discloses a vehicle track prediction method and device. The method comprises the following steps: when a vehicle runs, triggering a prediction program used for predicting a driving track of the vehicle; map feature information of the high-precision map is called and loaded to a memory, and the map feature information is static data; responding to the prediction instruction, and capturing dynamic sensing information in the running process of the vehicle; based on the positioning information of the vehicle, map feature information of an area where the vehicle is currently located is inquired from a memory; and inputting the inquired map feature information and the dynamic perception information into the prediction model, and predicting to obtain a predicted trajectory of the vehicle. The technical problem that the vehicle track cannot be predicted in real time in the prior art is solved.

Description

technical field [0001] The invention relates to the field of intelligent networked automatic driving, and in particular, to a method and device for predicting vehicle trajectory. Background technique [0002] When an autonomous vehicle is driving, it is necessary to predict the road and surrounding environment in advance to avoid safety accidents. However, the current vehicle trajectory prediction of autonomous vehicles mainly relies on the calculation of historical trajectories, and is only suitable for simple driving situations with a short prediction range. [0003] For the above problems, no effective solution has been proposed yet. SUMMARY OF THE INVENTION [0004] Embodiments of the present invention provide a method and device for predicting a vehicle trajectory, so as to at least solve the technical problem in the related art that the vehicle trajectory cannot be predicted in real time. [0005] According to an aspect of the embodiments of the present invention, ...
