Abstract: Example methods and apparatus for recognizing a vehicle lane change trend are described. One example method includes obtaining laser point cloud data of a detected target vehicle. A first distance relationship value between a center line of a lane in which the current vehicle is located and the target vehicle is obtained based on the laser point cloud data. A second distance relationship value between the center line of the lane and the target vehicle is obtained. First confidence of the first distance relationship values and second confidence of the second distance relationship values are calculated, and fusion distance relationship values are then calculated based on the first confidence and the second confidence. It is determined whether the target vehicle has a lane change trend based on the fusion distance relationship values.

Abstract: This application discloses a vehicle driving exit prediction method includes: obtaining a first location of the target vehicle at the target intersection and a driving direction of the target vehicle; obtaining N reference points respectively associated with N driving exits of the target intersection, where N is a positive integer; obtaining, based on the first location, the driving direction of the target vehicle, and the N reference points, likelihoods corresponding to the N driving exits respectively, where the likelihood indicates a probability that the target vehicle travels out of the target intersection from a corresponding driving exit; and obtaining a driving exit with a largest likelihood in the N driving exits as the driving exit of the target vehicle.
