Claim 16:
17. 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;
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; and
controlling operation of the trailer brake system in accordance with the second secondary control strategy in dependence on the determined coupling force exceeding the upper coupling force threshold, wherein the second secondary control strategy comprises decreasing a pressure level of the trailer brake system to reduce a braking force applied on the trailer.
