  • Patent number: 12633215
    Abstract: A computer-implemented traffic planning method controls a plurality of vehicles which are movable among multiple shared resources. The method includes receiving a transport mission; generating a root node representing an initial resource occupancy of the vehicles; generating a search tree from the root node, in which each edge represents a motion command and each node represents a resource occupancy, wherein each node is associated with a score related to the vehicles' fulfilment of the transport mission; identifying a target node with an acceptable score; and deriving a planned sequence of motion commands corresponding to a path to the target node. The score of a node includes a short-term component, which represents a cost of executing all motion commands from the root node to said node, and a long-term component, which is determined by the resource occupancy that the node represents.

  • Patent number: 12496926
    Abstract: The invention relates to a method for controlling charging of at least one electrically driven vehicle of a vehicle fleet including a plurality of vehicles at a charging area, the method includes the step of defining a reference minimum charging energy level for a battery of the vehicle. Further the method includes the step of determining a charging energy level of the battery of the vehicle and comparing the charging energy level with the reference minimum charging energy level. Lastly the method includes assigning a charging command to the vehicle to charge the vehicle if the determined charging energy level of the battery is below said reference minimum charging energy level, and wherein the charging command depends from a charging parameter or a combination of multiple charging parameters if the determined charging energy level of the battery of the vehicle is above said reference minimum charging energy level.

  • Publication number: 20250076877
    Abstract: A method to determine if a traffic situation comprising a plurality of heavy-duty vehicles following a plurality of guided vehicle trajectories in a defined area will lead to a vehicle deadlock is described. For example, one method includes generating a traffic situation representation for the defined area comprising, for each of the plurality of vehicles, an initial vehicle trajectory segment location and a subsequent deadlock status, inputting the traffic situation representation to a traffic situation deadlock classifier which has been trained to output a traffic situation deadlock classification based on an input representation of a traffic situation in the defined area, and, based on the input traffic situation representation, generating a predicted deadlock classification of a subsequent traffic situation for that input traffic situation representation.
