METHOD AND A SYSTEM FOR DETERMINING THE LOAD TRANSFERRED FROM A SEMI-TRAILER TO A FIRST AXLE OF A TOWING VEHICLE
First Claim
1. A method of determining a load (L1) transferred from a semi-trailer to a first axle of a towing vehicle, the towing vehicle having at least one further, second axle, the semi-trailer being partly supported by the towing vehicle at a supporting site thereof, wherein a position of the supporting site in relation to the axles of the towing vehicle is changeable, the method comprising:
- determining a first value representing a load (L2) transferred from the semi-trailer to the at least one further, second axle anddetermining a second value (d1, d2) representing the position of the supporting site in relation to the axles using a position detecting device, andcalculating a value representing the load (L1) transferred from the semi-trailer to the first axle based on said the first and second values.

Abstract
A method and a system determine the load transferred from a semi-trailer to a first axle of a towing vehicle which has at least one further, second axle. The semi-trailer is partly supported by the towing vehicle at a “fifth wheel”. A first value representing the load transferred from the semi-trailer to the second axle is determined by a load sensor and a second value representing the position of the “fifth wheel” in relation to said axles are also determined. Based on these first and second values a value representing the load transferred from the semi-trailer to the first axle is calculated by a calculator. The calculation may be based on the equation L1*d1=L2*d2 or L1=L2*d2/d1.

7. A system for determining a load (L1) transferred from a semi-trailer to a first axle of a towing vehicle, the towing vehicle having at least one further, second axle, the semi-trailer being partly supported by the towing vehicle at a supporting site thereof, the system comprising;
-
a load sensing device for determining a first value representing the load (L2) transferred from the semi-trailer to the at least one further, second axle and a position detecting device for determining a second value (d1, d2) representing the position of the supporting site in relation to the axles, and an electronic calculator adapted to receive signals from the load sensing device and from the position detecting device representing the first and second values, respectively, and to calculate a value representing the load (L1) transferred from the semi-trailer to the first axle based on the first and second values. - View Dependent Claims (8, 9, 10, 18, 19, 20)
