Systems and methods are provided for controlling operation of a trailer brake system associated with an agricultural vehicle-trailer combination. A coupling force between the vehicle and the trailer is determined and used to control operation of the trailer brake system in dependence thereon. A primary control strategy is used in dependence on the determined coupling force being within a coupling force range; and one or more secondary control strategies are used in dependence on the determined coupling force being outside of the coupling force range.

A brake control apparatus includes: a master cylinder that outputs a brake fluid at a master pressure; a master pressure changing device that can change the master pressure irrespective of an operation of a brake pedal; a brake actuator; and a control unit that executes antilock control by reducing a brake pressure of a target wheel. Modes of the antilock control include a normal mode and a pseudo mode. In the pseudo mode, the control unit operates the master pressure changing device such that the master pressure obtains a target value of the brake pressure of the target wheel, and changes the brake pressure of the target wheel in an interlocking manner with the master pressure. When the normal mode is unavailable, the control unit executes the antilock control in the pseudo mode.
