Abstract:
A method includes obtaining motive outputs demanded by a trip plan for a vehicle system having interconnected propulsion-generating vehicles, determining motive output capabilities of the propulsion-generating vehicles, and identifying segments of the trip where the motive output capabilities of the propulsion-generating vehicles exceed motive outputs demanded by the trip plan over the segments. The method further includes selecting one or more of the propulsion-generating vehicles for turning at least one of off or to idle in the one or more segments while one or more remaining propulsion-generating vehicles in the vehicle system remain on. The propulsion-generating vehicles are selected such that a total motive output capability of the one or more remaining propulsion-generating vehicles remains at least as great as the motive outputs demanded by the trip plan over the one or more segments.
Abstract:
A control system includes an energy management system and an isolation control system. The energy management system generates a trip plan that designates operational settings of a vehicle system having powered units that generate tractive effort to propel the vehicle system. The energy management system determines a tractive effort capability of the vehicle system and a demanded tractive effort of a trip. The energy management system identifies a tractive effort difference between the tractive effort capability of the vehicle system and the demanded tractive effort of the trip and selects at least one of the powered units based on the tractive effort difference. The isolation module remotely turns the selected powered unit to an OFF mode such that the vehicle system is propelled along the route during the trip by the powered units other than the selected powered unit.

Abstract:
A method for controllably linking propulsion units in a vehicle consist includes transmitting a linking signal having an identity of a lead propulsion unit. A remote propulsion unit is remotely controlled by the lead unit when the identity matches a designated identity stored onboard the remote unit. A de-linking signal is transmitted from the lead unit when the lead unit is to be decoupled from the vehicle consist. The de-linking signal includes a replacement identity of a replacement propulsion unit. A replacement linking signal is transmitted from a second lead unit. The remote propulsion unit allows the second lead propulsion unit to remotely control the operations of the remote propulsion unit when replacement identity stored onboard the remote propulsion unit matches an identity that is communicated in the replacement linking signal.
Abstract:
A vehicle control system includes a controller that determines a communication loss between a first vehicle and a second vehicle and/or a monitoring device in a vehicle system. The controller determines an operational restriction on movement of the vehicle system based on the communication loss that is determined, and obtains a transitional plan that designates operational settings of the vehicle system at different locations along a route being traveled by the vehicle system, different distances along the route, and/or different times. The controller also automatically changes the movement of the vehicle system according to the operational settings designated by the transitional plan to reduce the movement of the vehicle system to or below the operational restriction determined by the controller responsive to the communication loss being detected.
Abstract:
A detection system for a rail vehicle includes a control module, which has a sensor input for receiving a signal from a sensor. The control module is configured to receive the signal and to output information responsive to the signal. In operation, the control module and a sensor are deployed on board the rail vehicle. The sensor is configured to generate the signal responsive to detecting a designated condition on board the rail vehicle. When the condition occurs, the sensor outputs the signal, which is received by the control module. Responsive to the signal, the control module outputs the information, such as communicating information of the signal content to another rail vehicle, or to an off board location. The designated condition may be unauthorized use of a handheld wireless device in a rail vehicle, or intruder entry into an unmanned rail vehicle.
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.
