  • Publication number: 20240166201
    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.

  • Publication number: 20240124494
    Abstract: Described are multi-resonance-thermally-activated delay-fluorescence compounds containing (i) a polycyclic aromatic/heteroaromatic ligand in which a plurality aromatic/heteroaromatic rings are linked by boron and nitrogen atoms and (ii) an N-heterocyclic carbene ligand, with both ligands coordinated to a metal atom/ion that has a high spin-orbit coupling. The use of the high spin-orbit coupling of metals and/or metal ions facilitates the intersystem crossing and/or reversed intersystem crossing processes of MR-TADF emitters, thereby largely accelerating the rate of TADF and substantially shortening the lifetime of deleterious triplet excitons. The MR-TADF emitters can be used to fabricate blue to green emitting OLEDs.

  • Publication number: 20240051572
    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.

  • Publication number: 20230159056
    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.
