Abstract: A method for determining an orientation of a trailer, the trailer being configured to be coupled to a towing vehicle, includes detecting a relation of movements of at least two wheels of the trailer, upon moving the trailer, with at least one sensor arranged at the trailer for detecting a respective state of the at least two wheels. The method further includes calculating an orientation of a coupling device of the trailer based on the relation of the at least two wheels.

Abstract: An arrangement determines a gradient signal in a vehicle. The arrangement has: a position capture device that determines a vehicle position at a first and second time and ascertains therefrom a distance traveled as a motion vector, and a laser distance sensor on the vehicle front at an angle to a vehicle longitudinal axis and configured to emit a laser beam in a direction of a first measuring point in front of the vehicle at the first and second time, and a length sensor to ascertain the length of the laser beam and its associated vector at the first and second time, and at least one detection device to ascertain a differential vector from the motion vector and the ascertained vectors and to form a gradient signal therefrom.

Abstract: A device for controlling a signal connection in a vehicle is presented. The signal connection represents a connection between at least one control unit in a vehicle and at least one actuator in the vehicle. The device is configured to establish, and/or monitor, and/or disconnect the signal connection based on an input signal.

Abstract: A safety device for detecting manipulations on a bus system of a vehicle includes a receiver configured to connect to the bus system of the vehicle and to receive a signal from the bus system, an analyzer configured to analyze a transition between signal states of the signal, and an evaluator configured to evaluate the signal as a manipulated signal or an unmanipulated signal based on analysis performed by the analyzer.

Abstract: A method for operating an agricultural machine includes applying provided machine data of a work flow along a working route for an autonomous operation of the agricultural machine. The provided machine data includes a plurality of data sets. The method further includes recording, during the autonomous operation of the agricultural machine, a working position of the agricultural machine, and selecting and applying, as a function of the detected working position, a respective data set from the plurality of data sets of the provided machine data as a function of the detected working position.
