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 ref ), which is determined by a respective length of the at least one support leg (122). 10 After having reached the reference elevation (h ref ), 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 ref ) is detected. Thereafter, the coupling arrangement (111) is re-elevated to a level being equal to the reference elevation (h ref ). 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.

Abstract: The present invention relates to automatic elevation control of a motor vehicle's (110) chassis element (119) above a surface (150) on which the vehicle (110) is situated, such that at least one support leg (122a, 122b) of a free-standing loadable/unloadable cargo unit (120) is off-loaded, and thus the support leg can be disengaged. A height sensor means (118) registers a height parameter indicative of the elevation (h) and a pressure sensor means (113) registers a pressure parameter indicative of a fluid pressure level (P) in a fluid chamber (112) of a level control mechanism for the chassis element (119). A control unit (117) receives the height and pressure parameters, and in response thereto, produces a control signal (C) that causes the chassis element (119) to be elevated. During elevation of the chassis elemen t (119), the control unit (117) investigates whether or not a first criterion is fulfilled with respect to a test parameter expressing a ratio of the fluid pressure level (P) increase per unit of the elevation (h). If the first criterion is fulfilled, the control unit (117) investigates whether or not a second criterion is fulfilled with respect to the test parameter. Provided that also the second criterion is fulfilled, the control unit (117) causes the elevation of the chassis element (119) to be discontinued. Namely, at this point in time, the support leg (122a, 122b) has been off-loaded.

Abstract: The invention relates to a commercial vehicle and an arrangement for the vehicle (1) having a multiplicity of wheel shafts (4,5) and a load surface (2) which is supported by a longitudinal chassis element (3). The vehicle incorporates suspension means (8,10) of the air bellows spring type, which make it possible for the load surface to assume a first and a second position. The arrangement comprises a sensor means for detecting a parameter related to the length of the bellows when the load surface is in the second position, and a sensor adapted to detect a parameter which is related to the pressure of the air in the bellows when the load surface is in the second position and a load is arranged on the load surface. A calculation unit is adapted to calculate the weight which will act upon the first wheel shaft on the basis of the parameters of the air bellows spring.
