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 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 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.
Claims18
A system comprising:
- a first controller configured to monitor a communication pathway between the first controller and at least a second controller, the first controller configured to monitor the communication pathway to determine whether a first brake command sent from the second controller is communicated via the communication pathway to one or more brake devices of a vehicle,
- the first controller configured to implement a backup brake command to the one or more brake devices based on a presence of the first brake command,
- wherein the first controller is configured to be disposed onboard the vehicle with the second controller.
A method comprising:
- determining, using a first controller disposed on a first vehicle, that a first brake command sent from a second controller disposed on the first vehicle to one or more brake devices of a vehicle is communicated via a communication pathway to the one or more brake devices;
- and
- communicating a backup brake command from the first controller to the one or more brake devices based on a presence of the first brake command.
A system comprising:
- a first controller configured to monitor a communication pathway and determine whether a first brake command from a second controller is communicated via the communication pathway to one or more brake devices of a vehicle,
- the second controller 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,
- wherein the first controller is configured to be disposed onboard the vehicle with the second controller.
