  • Patent number: 10431092
    Abstract: A method for performing a cooperative driving maneuver and a vehicle. The method performs a cooperative driving maneuver which includes determining, by a first vehicle, a driving maneuver to be carried out; receiving maneuver information pertaining to a planned driving maneuver of a second vehicle by the first vehicle receiving surroundings information by the first vehicle, stipulating, by the first vehicle based on the received maneuver information and the received surroundings information, a maneuver trajectory for the driving maneuver to be carried out, and performing the driving maneuver by the first vehicle using the stipulated maneuver trajectory. Also disclosed is a way for vehicles to be better able to interpret received information pertaining to a planned driving maneuver of another vehicle to increase safety for the performance of a cooperative driving maneuver.

  • Publication number: 20190266892
    Abstract: A method captures data and transfers the data from a transmitter to a receiver, which is a transportation vehicle, and controls the capture and transfer of data. The method produces data and transfers the data from a transmitter to a receiver, which is a traffic participant. The data are based on a geographic environment model of the transmitter, wherein the geographic environment model includes a recognition of objects. Operations at the transmitter include capturing parameters of a transfer system for transferring the data and/or traffic-relevant parameters of the transmitter, producing the data in accordance with the recognized objects, and transferring the data in accordance with the parameters of the transfer system and/or the traffic-relevant parameters of the transmitter.

  • Patent number: 10386855
    Abstract: A method for the decentralized coordination of driving maneuvers of at least two motorized transportation vehicles. A planned trajectory and a desired trajectory are transferred from a first motorized transportation vehicle to a second motorized transportation vehicle. In the second motorized transportation vehicle, a planned trajectory of the second motorized transportation vehicle is compared with the desired trajectory of the first motorized transportation vehicle. The planned trajectory of the second motorized transportation vehicle is adapted in response to satisfaction of adaptation criterion. The planned and desired trajectories of the first motorized transportation vehicle are combined with a strategic trajectory of the first motorized transportation vehicle. The planned trajectory and a desired trajectory of the second motorized transportation vehicle are combined with a strategic trajectory of the second motorized transportation vehicle.

  • Patent number: 10304333
    Abstract: A method and a transportation vehicle communication system for determining a driving intention for a transportation vehicle. The driving intention includes information about a predicted driving maneuver. The method includes determining a position of the transportation vehicle; identifying a road section based on the position of the transportation vehicle and a digital map; obtaining information about internal trigger variables for determining a current driving intention based on on-board sensors or actuators of the transportation vehicle; and determining the driving intention based on the road section, the information about the internal trigger variables, and the one or more trigger conditions. One or more possible driving intentions are associated with the road section. One or more trigger conditions are associated with the one or more possible driving intentions based on one or more trigger variables.
