Problems solved by technology

[0003] However, in other vehicles, especially in commercial vehicles, the position detection with this sensing device is due to contamination of the optics by grease or wear in the trailer coupling may be problematic
In commercial vehicles there may also be high mechanical loads at the trailer coupler, which also makes it difficult to place sensors on commercial vehicles

Embodiment Construction

[0028] exist figure 1 The individual method steps S1 to S4 of the method for determining the orientation of a trailer 2 that can be coupled to a towing vehicle 4 are shown in their chronological order. In a first step S1, the movement process of the trailer 2 with the towing vehicle 4 is started, during which the wheels 5, 6 of the trailer 2 (as in the figure 2shown in ) can be moved. In a second step S2 the movement of the wheels 5 , 6 of the trailer 2 is detected while the trailer 2 is moving. In sub-step S2a, when the trailer 2 is moving, a first sensor (not shown) is used to detect the moving direction and rotational speed of the first wheel 5 of the trailer 2 . In another sub-step S2b, when the trailer 2 is moving, a second sensor (not shown) is used to detect the direction of movement and the rotational speed of the second wheel 6 of the trailer 2 . In a third step S3 the orientation 8 of the coupling device 7 is calculated based on the direction of movement and the ...

Abstract

The invention relates to a method and a control device for determining an orientation of a trailer (2) which can be coupled to a towing vehicle (4). When the trailer is moving, a relation of movementsof at least two wheels (5, 6) of the trailer is determined using at least one sensor arranged on the trailer, in order to detect a state of each of the at least two wheels, and the orientation of a coupling device of the trailer is determined on the basis of said relation.

Description

technical field [0001] The invention relates to a method for determining the orientation of a trailer that can be coupled to a towing vehicle. Background technique [0002] In passenger motor vehicles, it is known to detect the position of a trailer coupled to the passenger motor vehicle by means of optical systems or measuring systems integrated in the trailer adapter. [0003] In other vehicles, in particular commercial vehicles, however, position detection with such a sensor system can be problematic due to contamination of the optics by grease or wear in the trailer coupling. In commercial vehicles high mechanical loads can also occur at the trailer coupling, which also makes it difficult to provide sensors on commercial vehicles. Contents of the invention [0004] The invention thus provides solutions which are more reliable and in particular less dependent on environmental conditions for determining the orientation of a trailer which can be coupled to a towing vehic...
