A method for providing an object message about an object, recognized in surroundings of a road user, in a communication network for communicating with other road users. The road user includes a sensor system for detecting the surroundings and an evaluation unit for evaluating sensor data generated by the sensor system and transferring object messages via the communication network. The method includes: receiving sensor data, generated by the sensor system, in the evaluation unit; recognizing at least one object in the surroundings of the road user based on the sensor data, a movement parameter and a further object parameter being ascertained; calculating an object transfer priority; determining, based on the object transfer priority, whether the recognized object is to be included in an object message; and, if so, generating the object message including the recognized object, and sending the object message via the wireless communication network.

A method for providing a maneuver message for coordinating a maneuver between a road user and at least one further road user in a communication network. The method includes: receiving the communication data and/or the sensor data in the evaluation unit; determining a possible trajectory of the road user based on the communication data and/or the sensor data, at least one trajectory parameter describing a property of the possible trajectory being ascertained; calculating a trajectory transfer priority from the trajectory parameter, the trajectory transfer priority representing a relevance of the at least one possible trajectory for the road user and/or the further road user; determining, based on the trajectory transfer priority, whether the at least one possible trajectory is to be included in a maneuver message; if so: generating the maneuver message including the at least one possible trajectory, and sending the maneuver message via the communication network.

A method for transferring a message in a communications network for communication between a road user and at least one further road user. The road user and the further road user each include an evaluation unit for transferring messages via the communications network. The method includes: receiving a first message in the evaluation unit, the first message including message segments, each including a priority value; determining an instantaneous capacity utilization of the communications network; filtering message segments to be transferred out of the first message, based on the priority values and the instantaneous capacity utilization of the communications network; and generating a second message including the message segments to be transferred, and sending the second message via the communications network.

The present invention relates to a method of cooperatively coordinating future driving maneuvers of a vehicle with fellow maneuvers of at least one fellow vehicle, wherein trajectories for the vehicle are rated with an effort value each, trajectories and fellow trajectories of the fellow vehicle are combined into tuples, the trajectory and the associated effort value of a collision-free tuple are selected as reference trajectory and reference effort value, trajectories with a lower effort value than the reference effort value are classified as demand trajectories, trajectories with higher effort value than the reference effort value are classified as alternative trajectories, and a data packet having a trajectory set consisting of the reference trajectory and the associated reference effort value as well as at least one trajectory from a group comprising the demand trajectories and the alternative trajectories as well as the respective effort values is transmitted to the fellow vehicle.

A method is provided for maneuver planning and implementation for a vehicle by a vehicle-internal control unit. The control unit includes a strategic planning level for carrying out route planning, a tactical planning level for providing lane-accurate trajectories to possible destination points, and an operative planning level for selecting a destination point and a negotiable trajectory to the selected destination point. The planning levels have a cascading design. When each planning level is executed, an information exchange with neighboring vehicles is carried out via a communication link in order to ascertain collisions. When a collision is ascertained in at least one planning level, a maneuver coordination is carried out between the vehicles via the communication link. Moreover, a control unit is provided.

A redundance reduction method used in coding multichannel signals is proposed, where signals available in digitized form are predicted. A prediction error is computed, which is subsequently quantized and loaded for transmission over a transmission path. In the method, prediction is performed linearly in a backward-adaptive fashion for at least two channels simultaneously, and the statistical relationships of the signals within a channel and between at least two channels is taken into account. A device for decoding redundance-reduced multichannel signals is proposed. It comprises a linear backward-adaptive predictor for at least two channels.

In a method for reducing data in a multi-channel data transmission, existing cross-relations between the signal channels are determined with due consideration of the transit-time difference. Upon the data transmission, a signal channel, the predictor coefficients and transit-time differences obtained from the cross-relations ascertained, and the prediction error are transmitted. At the receiver, the signal of the second channel is reconstructed from the transmitted signal channel, the predictor coefficients, the transit-time difference, and the prediction error. In this way, the amount of data to be transmitted in the case of multi-channel video or audio signals is reduced.
