A WORKING UNIT COMPRISING A VEHICLE, A WORKING EQUIPMENT, AND A METHOD IN RELATION TO A WORKING UNIT

A working unit comprising a vehicle (2) and a working equipment (4) configured to load a load carrying device (6) on to said vehicle (2), said working unit comprises: -a sensor arrangement (8) comprising at least one sensor member arranged at said working unit, said at least one sensor member is configured to determine an angle, denoted deviation angle DA, between a longitudinal axis A1 of said vehicle and a longitudinal axis A2 of said load carrying device (6). The control system is configured to compare said DA to a predetermined maximum deviation angle DAMAX, and if said DA is less than said DAMAX the vehicle is set in a loading mode comprising applying a loading procedure comprising: -engaging a loading tool (14) of the working equipment (4) with an attachment part (16) at a first end (18) of the load carrying device (6); -lifting the first end (18) of the load carrying device (6) by said loading tool (14) while a second end (20) of the load carrying device (6) is on ground; -generating a first set of operation instructions to the vehicle for adjusting the position of the vehicle (2) to decrease the DA while the working equipment (4) lifts said first end (18) of the load carrying device (6); -monitoring the DA during the adjustment of the vehicle position, and comparing the DA to a predetermined loading threshold deviation angle DALT, being less than said DAMAX, -generating a second set of operation instructions for the working equipment (4) to move the load carrying device (6) on to the vehicle (2) in response to the DA being less than the DALT.
