Claim 11:
12. 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; and
generating and outputting control signals for controlling operation of the trailer brake system in dependence on the determined coupling force;
wherein the method comprises:
controlling operation of the trailer brake system in accordance with a primary control strategy in dependence on the determined coupling force being within a 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
determining a coupling force associated with the coupling between the vehicle and the trailer in dependence on a measure of an operating parameter of a transmission of the vehicle-trailer combination.
