Vehicle Control System And Method

Abstract:

A vehicle control system includes a first controller configured to communicate a first brake command to one or more brake devices of a vehicle system via a communication pathway. The system also includes 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 also is configured to implement a 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.
