Abstract: The invention relates to a radar reflector (1) for reflecting radar radiation (2), comprising at least one reflection element (5) rotatable about a central axis (4) of the radar reflector (1) and an adjusting device (7) for changing and/or parameterizing a characteristic of a radar echo (3) of the radar reflector (1). At least one of the following parameters can be changed by means of the adjusting device (7): the angular velocity ? of rotational motion of the at least one reflection element (5) about the central axis (4); an effective reflection area of the at least one reflection element (5); and a fastening position p of the at least one reflection element (5) relative to the central axis (4).

Abstract: The invention relates to a technology for transversely and longitudinally guiding reversing of a commercial vehicle (100)during controlled parking and/or manoeuvring of the commercial vehicle (100) as a following vehicle in accordance with a leading vehicle (200) in the surroundings of the commercial vehicle (100). The commercial vehicle (100) comprises at least one sensor (102)and/or at least one data interface (104) for sensing data of the surroundings of the commercial vehicle (100), the sensed surroundings containing the commercial vehicle (100) and/or the leading vehicle (200). Alternatively or in addition, the commercial vehicle(100)comprises at least one data interface (104)for sensing a control instruction for transverse and longitudinal guidance from the leading vehicle (200)in the surroundings of the commercial vehicle (100).

Abstract: A detection device configured to be arranged on a motor vehicle includes at least one bracket construction for mounting on a front of the motor vehicle. The at least one bracket construction has at least one detection element for detecting a road topography in the direction of travel in front of the motor vehicle under a water surface to detect obstacles or a water depth.
