Abstract: A method for data recording of a vehicle combination is disclosed, where the vehicle combination includes a first vehicle and a second vehicle. The first vehicle includes a first data recorder and the second vehicle includes a second data recorder. The method includes collecting, by the first data recorder, first vehicle operational data of the first vehicle; and collecting, by the first data recorder, second vehicle operational data of the second vehicle.

Abstract: A method estimates an articulation angle between a towing vehicle and a trailer with respect to a pivot. The method determines a distance between an instantaneous center of velocity of the towing vehicle and a center of at least one axle of the towing vehicle representative for a rotation of the towing vehicle about the instantaneous center of velocity of the towing vehicle and/or a distance between an instantaneous center of velocity of the trailer and a center of at least one axle of the trailer representative for a rotation of the trailer about the instantaneous center of velocity of the trailer. The method determines at least one instantaneous speed representative for a wheel speed of at least one wheel of the towing vehicle and/or the trailer, wherein the at least one instantaneous speed refers to the at least one determined distance, and estimates the articulation angle based on the at least one determined instantaneous speed and the at least one determined distance.

Abstract: An apparatus for validating a position or an orientation of one or more sensors of an autonomous vehicle is provided. The one or more sensors provide consecutive sensor data of surroundings of the vehicle. The apparatus includes a validation module, which is configured to compare the consecutive sensor data and to validate a position or an orientation of at least one sensor of the one or more sensors, based on a deviation in the consecutive sensor data.

Abstract: In an electronically commutated DC motor having a stator unit (5) and a rotor unit (1) which is in the form of an external rotor, and having stationary sintered bearings (8, 9), the invention proposes that the rotor unit (1) is conductively connected to the shaft (3) in order to connect a conductive shielding, which is formed on the rotor unit (1), to a defined electrical potential, and that the sintered bearing (8, 9) is conductively connected to the potential, so that the shielding of the rotor unit (1) is capacitively coupled to the potential by means of the electrically insulating, oil-filled bearing gap which is arranged between the shaft (3) and the sintered bearing (8, 9). Therefore, a sliding contact is not required.
