Publication number: 20240317284Abstract: A control system and method includes obtaining information associated with a vehicle system that includes one or more vehicles that are configured to move along a route. The vehicle system information is applied to a trip simulation to determine how the vehicle system is expected operate while the vehicle system moves along the route. The trip simulation includes one or more anticipated operating conditions of the vehicle system and/or anticipated route conditions the vehicle system is expected to be exposed to as the vehicle system moves along the route. It is determined whether the vehicle system will be able to stop at one or more locations along the route based on the application of the vehicle system information to the trip simulation. An alert is communicated responsive to determining that the vehicle system will be unable to stop at the one or more locations along the route.Type: ApplicationFiled: January 18, 2024Publication date: September 26, 2024Inventors: James A. Oswald, Alan Tentinger, Alex Young, Phillip A. Burgart, Ann K. Grimm

Patent number: 11953338Abstract: A remote initialization system and method for a vehicle system receive trip data for an upcoming trip at an off-board device. Using the off-board device, the trip data is communicated to the different back-office systems, and one or more of mandatory directives or software configuration requirements are received at the off-board device from the different back-office systems. An initialization data set that includes at least some of the trip data and at least some of the one or more of the mandatory directives or the software configuration requirements is communicated from the off-board device to an onboard controller of the vehicle system. The initialization data set is configured to be used by the onboard controller to control movement of the vehicle system in the different sets of the routes.Type: GrantFiled: August 27, 2021Date of Patent: April 9, 2024Assignee: WESTINGHOUSE AIR BRAKE TECHNOLOGIES CORPORATIONInventors: Janmejay Tripathy, Jeffrey D.
