Abstract:
A system and method communicate a command message from a lead vehicle in a vehicle consist having remote vehicles and the lead vehicle. The command message includes a directive for controlling operations of the remote vehicles. The command message is received at the remote vehicles and reply messages are communicated in response thereto. The reply messages include statuses of the remote vehicles. Responsive to determining that the lead vehicle does not receive the reply message from one or more of the remote vehicles, the statuses of the one or more remote vehicles from which the reply messages are not received at the lead vehicle are sent and/or combined into an individual or concatenated relayed message. The individual or concatenated relayed messages are communicated to the lead vehicle such that the lead vehicle receives the statuses of the one or more remote vehicles.
Abstract:
A method and system for converting protocols of messages receive a first wireless message onboard a first vehicle in a vehicle consist that includes the first vehicle and one or more additional vehicles. The method and system also determine a first protocol of the first wireless message, determine a different, second protocol used by a control system disposed onboard the first vehicle, change the first wireless message to a different, second message by modifying the first protocol of the first wireless message to the different, second protocol, and communicate the second message to the control system.
Abstract:
In a system and method for communicating data between first and second vehicles, a first electronic component in the first vehicle is monitored to determine if the component is in (or enters) a failure state. In the failure state, the first electronic component is unable to perform a designated function. Upon determining the failure state, data is transmitted from the first vehicle to a second electronic component on the second vehicle, over a communication channel linking the first vehicle and the second vehicle. The second electronic component is operated based on the transmitted data, with the second electronic component performing the designated function that the first electronic component is unable to perform.
Abstract:
A sensing system includes a leading sensor, a trailing sensor, and a route examining unit. The leading sensor is onboard a first vehicle of a vehicle system that is traveling along a route. The leading sensor measures first characteristics of the route as the vehicle system moves along the route. The trailing sensor is disposed onboard a second vehicle of the vehicle system. The trailing sensor measures second characteristics of the route as the vehicle system moves along the route. The route examining unit is disposed onboard the vehicle system and receives the first characteristics of the route and the second characteristics of the route to compare the first characteristics with the second characteristics. The route examining unit also identifies a segment of the route as being damaged based on a comparison of the first characteristics with the second characteristics.
Abstract:
A method includes obtaining data relating to operation of a first vehicle in a vehicle consist that includes the first vehicle and a second vehicle communicatively coupled with each other by a communication channel. The first vehicle includes a first electronic component performing functions for the first vehicle using the first data. The method also includes communicating the first data over the communication channel from the first vehicle to a second electronic component disposed onboard the second vehicle responsive to the first electronic component being unable to perform the one or more functions for the first vehicle using the first data. The method further includes performing the functions of the first electronic component with the second electronic component using the first data that is received from the first vehicle.
Abstract:
In a communication system and method, a vehicle identifier is determined for a first remote vehicle that is included in a vehicle consist formed from a lead vehicle and at least the first remote vehicle. The system and method communicate a wireless linking message addressed to the vehicle identifier from the lead vehicle to the first remote vehicle, and establish a communication link between the lead vehicle and the first remote vehicle responsive to receipt of the wireless linking message at the first remote vehicle. The communication link is established such that movement of the first remote vehicle is remotely controlled from the lead vehicle via the communication link. The communication link is established without an operator entering the first remote vehicle.

Abstract:
A method for determining a slack condition of a vehicle system includes determining when each of first and second vehicles reaches a designated location along a route. The method also includes communicating a response message from the second vehicle to the first vehicle responsive to the second vehicle reaching the designated location, calculating a separation distance between the first vehicle and the second vehicle based on a time delay between a first time when the first vehicle reached the designated location and a second time when the second vehicle reached the designated location, and determining a slack condition of the vehicle system based on the separation distance. The slack condition is representative of an amount of slack in the vehicle system between the first and second vehicles.
Abstract:
A system and method for determining an orientation of a vehicle are provided. The system and method determine (with a sensor assembly disposed onboard a first vehicle) a direction in which a fluid flows within the first vehicle. The first vehicle is included in a vehicle consist with a second vehicle. The orientation of the first vehicle relative to the second vehicle is determined based at least in part on the direction in which the fluid flows within the first vehicle. The fluid may be air in an air brake pipe of the vehicle consist.
Abstract:
A locomotive communication system includes a wireless communication device and a controller that controls operation of the wireless communication device. The controller directs the wireless communication device to switch between operating in an off-board communication mode and operating in an onboard communication mode. The wireless communication device communicates a remote data signal with an off-board location while the wireless communication device is operating in the off-board communication mode and the wireless communication device communicates a local data signal between the propulsion-generating vehicles of the vehicle system while the wireless communication device is operating in the onboard communication mode.
