Brake control system

A system comprising:

• an interface controller configured to communicate with different control paths of sources for control of a brake system of a vehicle system, each of the control paths configured to communicate a control signal from a different source of the sources to control operation of the brake system, the sources including at least a first source and a trip management system, the trip management system configured to determine operational settings for controlling the vehicle system during an upcoming segment of a trip of the vehicle system that reduces fuel consumption, emission generation, or both fuel consumption and emission generation of the vehicle system relative to the vehicle system traveling according to settings other than the operational settings determined by the trip management system, the operational settings determined by the trip management system including throttle settings and brake settings of the vehicle system,
• the interface controller configured to arbitrate between the control signals concurrently received from the different sources via the control paths to dictate whether the trip management system or at least the first source controls operation of the brake system at different times and prevent control by other sources of the different sources from concurrently controlling the operation of the brake system.
