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...
