  • Publication number: 20220119020
    Abstract: A control system includes a controller that may determine whether a second speed limit, which is less than or equal to a first speed limit, is in effect for a segment of the route. The controller may switch one or more operational settings of a vehicle from the first speed limit to the second speed limit, and may operate the vehicle at the first speed limit outside of the segment of the route and operate the vehicle at or below the second speed limit while the vehicle is approaching or within the segment of the route.

  • Patent number: 11208125
    Abstract: A control system dictates operational settings of a rail vehicle system based a transitory second speed limit that is no faster than a current first speed limit and which is issued for a determined segment of the track for a determined time period. The control system obtains a current time, determines whether the transitory second speed limit has started, is in effect, or has expired based on the current time relative to the determined time period, and, in response to such determination, performs one or more of (a) generate a prompt to indicate that the determined time period has expired, (b) operate the rail vehicle system at the first speed limit, and/or (c) modify the operational settings of the rail vehicle system to exceed the second speed limit in the determined segment but not exceed the first speed limit for the determined segment.

  • Patent number: 10279823
    Abstract: A method includes generating a trip plan that dictates operational settings to be implemented by a vehicle system moving along a route. The trip plan is based on a temporary work order issued for a restricted segment of the route. The work order provides a maximum speed through the restricted segment for a limited time period that is expressed using a time standard. One or more of the operational settings of the trip plan specify movement of the vehicle system through the restricted segment at a vehicle speed that is less than or equal to the maximum speed. In response to determining that the temporary work order has expired, the method includes at least one of prompting an operator of the vehicle system to confirm that the work order has expired or generating a new trip plan in which the vehicle system exceeds the maximum speed through the restricted segment.

  • Patent number: 9815470
    Abstract: An energy management system and method for a vehicle system operate the vehicle system according to a current trip plan as the vehicle system travels along a route during a trip. The current trip plan designates operational settings of the vehicle system. The system and method also revise the current trip plan into a revised trip plan responsive to current, actual operation of the vehicle system differing from the current trip plan by at least a designated threshold amount. The revised trip plan designates operational settings of the vehicle system and includes an initial designated operational setting that matches the current, actual operation of the vehicle system.
