Abstract: This application provides example driving behavior determining methods and example related devices thereof. One example method in this application includes obtaining first driving data of a first vehicle and second driving data of a second vehicle. A driving behavior set in which the first vehicle has no risk of collision with the second vehicle is obtained based on the first driving data and the second driving data. The first driving data and the second driving data are processed by using a target model to obtain a predicted driving behavior of the first vehicle. In response to detecting that the driving behavior set includes the predicted driving behavior, the predicted driving behavior is determined as a driving behavior to be performed by the first vehicle.

Abstract: The planning method includes: obtaining a distance map; determining a first horizontal background cost potential field in a near-field range based on the distance map, where the first horizontal background cost potential field is a first repulsion field formed by an obstacle at a horizontal location on the traveling apparatus, the first horizontal background cost potential field includes a target minimum-value point, background costs on two horizontal sides of the target minimum-value point feature monotonicity, and the background cost represents a near-field horizontal collision cost caused by the obstacle at the horizontal location in the near-field range to the traveling apparatus; and determining a current obstacle avoidance path based on the first horizontal background cost potential field. The method for planning an obstacle avoidance path in embodiments of this application enables the traveling apparatus to avoid an obstacle safely and stably in a complex and narrow traffic scenario.

Abstract: The present disclosure relates to methods and apparatuses for decision making. An example method includes obtaining a predicted moving track of an ego vehicle and predicted moving tracks of obstacles around the ego vehicle. The method further includes determining a game object. The game object is an obstacle that is in the obstacles around the ego vehicle and whose predicted moving track intersects the predicted moving track of the ego vehicle or whose distance from the ego vehicle is less than a specified threshold. The method further includes constructing one sampling game space for each game object based on vehicle information of the ego vehicle, obstacle information of the game object, and road condition information that are collected by a sensor system. Each sampling game space includes one or more game policies. The method further includes calculating a policy cost of each game policy.

Abstract: A trajectory planning method and a related device are provided, to plan a sub-lane-level trajectory, so that an autonomous vehicle drives along the sub-lane-level trajectory, and driving stability and safety of the autonomous vehicle are improved by using the sub-lane-level trajectory. Target information is obtained, where the target information includes at least one of a driving status of a target vehicle and first road condition information. A first planned trajectory of the target vehicle is determined based on the target information, where the first planned trajectory includes a target trajectory, the target trajectory is parallel to a center line of a lane, and the target trajectory is located in an area between the center line of the lane and a boundary of the lane, or on the boundary
