Abstract

The present invention relates to automatic adjustment of a tow vehicle's (110) coupling arrangement (111), such that a trailer (120) can be disengaged from the vehicle (110) as smoothly as 5 possible. After engagement of at least one support leg (122) of the trailer (120), a fluid operated level control mechanism (112, 114) lowers the coupling arrangement (111) until this arrange- m e n t reaches a reference elevation (h<SUB>ref</SUB> ), which is determined by a respective length of the at least one support leg (122). 10 After having reached the reference elevation (h<SUB>ref</SUB>), the fluid pressure (P) in a fluid chamber (112) of the level control mechanism is continued to be lowered until a lowering of the coupling arrangement (111) below the reference elevation (h<SUB>ref</SUB>) is detected. Thereafter, the coupling arrangement (111) is re-elevated to a level being equal to the reference elevation (h<SUB>ref</SUB>). At this point in time, the trailer (120) can be disengaged from the vehicle (110) without risking that the vehicle (110) drops down or hops up.
