Abstract: A method for arranging individual vehicles in a platoon includes determining a desired longitudinal offset and/or a desired transverse offset for at least one respective individual vehicle by determining at least one wind factor that characterizes how prevailing wind in a vehicle environment acts on the at least one respective individual vehicle of the platoon. The method further includes specifying the desired transverse offset and/or the desired longitudinal offset for the at least one respective individual vehicle of the platoon in dependence upon the at least one wind factor in such a manner that an air resistance acting on the at least one respective individual vehicle of the platoon reduces under the prevailing wind.

Abstract: A method for determining, by a utility vehicle having a trailer coupling, an articulation angle between the utility vehicle and a coupled vehicle trailer includes determining, with a model, a modelled value of the articulation angle or an articulation angle change. The method further includes determining, with a sensor unit, a measured value of an articulation angle or of an articulation angle change, and deriving, from the measured value, a correction value. The method additionally includes correcting the modelled value as a function of the correction value, and outputting the corrected modelled value as an output value of an articulation angle.

Abstract: A method for distance control of a subject vehicle in relation to a front vehicle. The method includes setting, by an adaptive cruise control of the subject vehicle, an automatic distance control mode, wherein: a front object in front of the subject vehicle is detected by an environmental detection system of the subject vehicle, the front object is recognized as the front vehicle, and a distance to the front vehicle is regulated to an adaptive cruise control (ACC) target distance. The method further includes establishing that a safe following driving situation is present based on at least one criteria being met. The method additionally includes outputting, to a driver upon establishing that the safe following driving situation is present, a display signal, and setting, upon input of a confirmation signal by the driver, an automatic distance control platooning mode.

Abstract: Disclosed is a method for operating a rotational speed sensor comprising a sensor element in a vehicle, wherein the sensor element interacts with a magnet wheel on a wheel of the vehicle and an effective parameter generated by the interaction of the magnet wheel with the sensor element is evaluated in the form of a measurand in an evaluation module and, depending on the measurand, an output variable characterizing the rotational speed of the wheel is output, wherein the sensor element is supplied via the evaluation module with a sensor voltage influencing the measurand. A sensor assembly is also disclosed.

Abstract: A sensor system, for determining an angular change between a utility vehicle and a coupled vehicle trailer, includes a sensor unit having a wheel mounted so as to be rotatable about an axis, and a rotary encoder connected to the wheel and configured to detect a change in position of the wheel. The sensor system further includes a mount having at least one first fixed part configured to connect the sensor system to the utility vehicle or a part thereof, and at least one movable part connected to the sensor unit and mounted so as to be movable on the fixed part. In addition, the sensor system includes a positioning mechanism configured to provide sprung bearing of the movable part in an operating position such that the wheel of the sensor unit can be moved into contact with a vehicle trailer or a part of the vehicle trailer.

Abstract: A method for specifying switching parameters of a solenoid control valve in a braking system of a vehicle includes stipulating a test vehicle acceleration and ascertaining at least two test pulse sequences. The test pulse sequences are each ascertained on the basis of the stipulated test vehicle acceleration and on the basis of switching parameter default values for the respective solenoid control valve, and the test pulse sequences have actuation pulses and adjoining nonactuation pulses. During an actuation pulse an activation of the respective solenoid control valve and during a nonactuation pulse a deactivation of the respective solenoid control valve takes place. The method further includes actuating the respective solenoid control valve using the at least two test pulse sequences in order to cause at least two test braking operations, wherein the respective test pulse sequence causes an alteration of a braking pressure at a service brake.
