Working unit, a working equipment, and a method in relation to a working unit

A working equipment configured to load a load carrying device onto a vehicle, said working equipment comprising:

• a sensor arrangement comprising at least one sensor member arranged at said working equipment, said at least one sensor member being configured to determine a deviation angle between a longitudinal axis of said vehicle and a longitudinal axis of said load carrying device, and to generate an angle deviation signal in dependence thereto, and
• a control system configured to receive said angle deviation signal, to compare said deviation angle to a predetermined maximum deviation angle, and if said deviation angle is less than said maximum deviation angle to set the vehicle in a loading mode for applying a loading procedure, the control system being configured to carry out the loading procedure that includes:
• engaging a loading tool of the working equipment with an attachment part at a first end of the load carrying device;
• lifting the first end of the load carrying device by said loading tool while a second end of the load carrying device is on ground;
• generating a first set of operation instructions for adjusting the position of the vehicle to decrease the deviation angle while the working equipment lifts said first end of the load carrying device;
• monitoring the deviation angle during the adjustment of the vehicle position, and comparing the deviation angle to a predetermined loading threshold deviation angle, being less than said maximum deviation angle,
• generating a second set of operation instructions for the working equipment to move the load carrying device on to the vehicle in response to the deviation angle being less than the threshold deviation angle.

A method in relation to a working unit that comprises a vehicle and a working equipment configured to load a load carrying device on to said vehicle, said method comprising:

• determining a deviation angle, between a longitudinal axis of said vehicle and a longitudinal axis of said load carrying device;
• generating a deviation angle signal in dependence thereto, and
• comparing said deviation angle to a predetermined maximum deviation angle, and if said deviation angle is less than said maximum deviation angle setting the vehicle in a loading mode comprising applying a loading procedure, the loading procedure including:
• engaging a loading tool of the working equipment with an attachment part at a first end of the load carrying device;
• lifting the first end of the load carrying device by said loading tool while a second end of the load carrying device is on ground;
• generating a first set of operation instructions for adjusting the position of the vehicle to decrease the deviation angle while the working equipment lifts said first end of the load carrying device;
• monitoring the deviation angle during the adjustment of the vehicle position and comparing the deviation angle to a predetermined loading threshold deviation angle, being less than said maximum deviation angle, and
• generating a second set of operation instructions for the working equipment to move the load carrying device on to the vehicle in response to the deviation angle being less than the threshold deviation angle.
