Problems solved by technology

The disadvantage is that the height adjustment of the trailer drawbar must be made by the driver
So in some cases the driver has to get in and out of the vehicle several times, which is uncomfortable and can be a waste of time
In addition, depending on the design and loading of the trailer, adjusting the height of the trailer drawbar can also be difficult, time-consuming or uncomfortable

Embodiment Construction

[0035] exist figure 1 The individual steps of the exemplary method are shown in FIG. There, a motor vehicle 120 is shown with a trailer coupling 122 and a trailer 121 with a coupling element 123 . Arrows show the movement of the motor vehicle.

[0036] In method step 106 , motor vehicle 120 is automatically adjusted to initial position AP close to the trailer.

[0037] In method step 108 , vehicle 120 is in initial position AP. The rear axle is lowered by the air suspension system (indicated by arrow 130 ), so that the trailer coupling 122 is at a height H above the ground. In this case, the height H is determined such that the highest point of the trailer coupling device 122 is located below the lowest point of the coupling element 123 .

[0038] In method step 112 , vehicle 120 is automatically adjusted into coupling position P such that trailer coupling device 122 is located substantially vertically below coupling element 123 .

[0039] In method step 113 , the rear axle...

Abstract

The invention relates to a method for coupling a motor vehicle with a trailer coupling device to a coupling element of a trailer, which method is at least semi-automatically based on data detected by means of an environmental sensor system, in particular of an environmental sensor system of the motor vehicle A motor vehicle is controlled in a controlled manner, wherein a controlled height change is carried out at at least one axle on the basis of detected data by means of an air suspension system of the motor vehicle. The invention also relates to a control device for carrying out the method.

Description

technical field [0001] The invention relates to a method for coupling a trailer to a motor vehicle. Background technique [0002] Motor vehicles are now increasingly equipped with environment sensing systems which are able to detect objects located in the environment of the vehicle. Data from such environmental sensors can be used to plan and execute automated maneuvers of the vehicle. Such methods are known, for example, from parking assistance systems. [0003] Similar to automatic parking systems, assistance systems are also known for coupling a trailer to the vehicle. [0004] Especially in the dark or in bad weather conditions, especially when the driver is alone, it can be difficult or uncomfortable for the driver to adjust properly for coupling the trailer and coupling the trailer. It is often necessary to get in and out of the vehicle many times, and the precise adjustment of the control requires a certain skill of the driver. Depending on the design and load sta...
