Vehicle Control System And Method

A method comprising:

• monitoring a communication pathway of a vehicle system for a first brake command communicated from a first controller to one or more brake devices of the vehicle system, the communication pathway monitored by a second controller;
• determining, using the second controller, that the first brake command from the first controller is communicated via the communication pathway to the one or more brake devices;
• and
• implementing a backup brake command, using the second controller, to the one or more brake devices based on a presence of the first brake command and a level of brake application dictated by the first brake command.

A system comprising:

• a first controller configured to electrically communicate a first brake command to one or more brake devices of a vehicle system via a communication pathway;
• and
• a second controller configured to monitor the communication pathway to determine whether the first brake command from the first controller is communicated via the communication pathway to the one or more brake devices,
• the second controller is configured to implement a pneumatic backup brake command to the one or more brake devices based on a presence of the first brake command and a level of brake application dictated by the first brake command.
