Claim 17:
18. A method of controlling operation of a trailer brake system associated with an agricultural vehicle-trailer combination comprising a vehicle and a trailer, the method comprising:
determining a coupling force between the vehicle and the trailer;
comparing the determined coupling force with an upper coupling force threshold and a lower coupling force threshold to determine whether the coupling force is within a coupling force range;
generating and outputting control signals for controlling operation of the trailer brake system in dependence on the determined coupling force;
controlling operation of the trailer brake system in accordance with a primary control strategy in dependence on the determined coupling force being within the coupling force range; and
controlling operation of the trailer brake system in accordance with at least one secondary control strategy in dependence on the determined coupling force being outside of the coupling force range;
wherein the lower coupling force threshold corresponds to a coupling force at a level whereby at least one of the force applied and the yaw moment resulting from the force exceeds a preselected level for the vehicle-trailer combination; and
wherein the preselected level is dependent on at least one parameter selected from the group consisting of the mass of the vehicle, the wheelbase of the vehicle, the wheelbase of the trailer, the wheel width of the vehicle, and the wheel width of the trailer.
