Systems and methods are provided for controlling operation of a trailer brake system associated with an agricultural vehicle, comprising: determining a coupling force associated with a coupling point for providing a coupling between the vehicle and a trailer, determining, in dependence on the coupling force, the presence of a trailer coupled to the vehicle at the coupling point; and controlling one or more components of the vehicle in dependence on the determination of the presence of the trailer.

Trailer brake control system

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.

Systems and methods are provided for controlling operation of a trailer brake system associated with an agricultural vehicle-trailer combination. Using a driver deceleration demand a pressure level and/or duration for a preliminary pressure peak to be provided in one or more fluid lines of the trailer brake system is determined. A trailer brake signal is generated for controlling the trailer brake system in accordance with the preliminary pressure peak.

Systems and methods are provided for controlling operation of a trailer brake system associated with an agricultural vehicle-trailer combination, comprising: determining abase value for a temperature associated with the trailer brake system; determining a coupling force between the vehicle and the trailer; determining a corrected value for the temperature associated with the trailer brake system in dependence on the determined coupling force; and controlling one or more components of the vehicle trailer combination in dependence on the corrected value.

A vehicle brake circuit including a brake actuator, a manually operable valve, an electrically operable valve and a fluid reservoir for the supply of fluid to the actuator. The manually operated valve may be connected to the fluid reservoir either directly or indirectly through the electrically operable valve, when its position blocks a direct fluid connection with the fluid reservoir. The electrically operated valve controls activation or deactivation of the actuator except when the mechanically operated valve is in an unblocked position and overrides the electrically operated valves control of the actuator.
