Claim 0:
1. A control system for controlling operation of a trailer brake system associated with an agricultural vehicle-trailer combination, the control system comprising a vehicle control unit, and being configured to:
determine a coupling force between the vehicle and the trailer;
generate and output control signals for controlling operation of the trailer brake system in dependence on the determined coupling force; and
compare 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;
wherein the control system is configured to:
control 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;
control operation of the trailer brake system in accordance with at least one secondary control strategy in dependence on the determined coupling force exceeding the upper coupling force threshold, wherein the second at least one secondary control strategy comprises decreasing a pressure level of the trailer brake system to reduce a braking force applied on the trailer.
