Abstract
Systems and methods are provided for controlling operation of a trailer brake system associated with an agricultural vehicle-trailer combination. A HMI component used by the operator to provide a deceleration input to the trailer brake system is identified. Based on this a pressure level to be provided in one or more fluid lines of the trailer brake system is determined. A trailer brake signal for is generated and output controlling the trailer brake system to provide the determined pressure.

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:
- identify a drive lever used by the operator to provide a deceleration input to the trailer brake system;
- determine a pressure level for a pilot pressure to be provided in one or more fluid lines of the trailer brake system in dependence on an acceleration rate input associated with at least one drive lever parameter selected from the group consisting of a position of the drive lever and a motion of the drive lever;
- increase the pressure level of the pilot pressure with increasing magnitudes of deceleration as determined from the acceleration rate input;
- generate a trailer brake signal for controlling the trailer brake system to provide the pilot pressure;
- and
- forward the trailer brake signal to the trailer brake control system to control operation thereof.
