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 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 weight sensing system particularly useful for trailers. An axle tube is mounted to the vehicle or trailer through its suspension members that may be leaf springs. A mounting block is affixed to the axle tube for mounting a strain gauge. The mounting block is fixed to the axle tube between the suspension members connected to the axle tube. The mounting block has a mounting surface opposite to the mating surface and a notch extends from the mating surface toward the mounting surface. The notch terminates between the mating surface and the mounting surface. The notch separates rigidified sections of the mounting block and the rigidified sections straddle the notch. The stain gauge measures strain in the axle and thereby generates a signal proportional to the weight on the trailer. The signal can be used to properly proportion a brake system on the trailer.

A brake control system is for a vehicle containing an internal controller for outputting an internal control variable for at least one brake actuator. An interface receives an external control variable for the at least one brake actuator from an external controller. A decision circuit has at least two inputs for receiving the internal control variable and the external control variable and an output for outputting a control signal for the at least one brake actuator. The control signal depends on the received internal control variable and/or the received external control variable.

A trailer spring brake valve is provided for a vehicle air braking system. The trailer spring brake valve comprises a number of components arranged to cooperate together to provide type of brake priority based upon trailer weight.

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.
