SYSTEMS AND METHODS FOR CONTROLLING WARNINGS AT VEHICLE CROSSINGS
First Claim
1. A system comprising:
- a timing determination module configured to be disposed onboard an approaching vehicle system;
wherein the timing determination module is configured to determine one or more arrival times of the approaching vehicle system, during travel of the approaching vehicle system along a first route toward a crossing between the first route and a second route, to reach the crossing and to repeatedly communicate notification messages having the one or more arrival times to a remote crossing system that is configured to activate one or more warning devices disposed at or near the crossing to notify other vehicles on the second route that the approaching vehicle system is approaching the crossing along the first route, the timing determination module configured to determine the one or more arrival times at different respective locations along the first route as the approaching vehicle system travels toward the crossing.

Abstract
A system includes a timing determination module configured to be disposed onboard an approaching vehicle system during travel of the approaching vehicle system along a first route toward a crossing between the first route and a second route. The timing determination module is configured to determine one or more arrival times of the approaching vehicle system to reach the crossing and to repeatedly communicate notification messages having the one or more arrival times to a remote crossing system that is configured to activate one or more warning devices disposed at or near the crossing to notify other vehicles on the second route that the approaching vehicle system is approaching the crossing along the first route. The timing determination module is configured to determine the one or more arrival times at different respective locations along the first route as the approaching vehicle system travels toward the crossing.

8. A method comprising:
-
determining, onboard an approaching vehicle system, one or more arrival times of the approaching vehicle system during travel of the approaching vehicle system along a first route toward a crossing between the first route and a second route; and repeatedly communicating notification messages with the one or more arrival times to a remote crossing system that is configured to activate one or more warning devices disposed at or near the crossing to notify other vehicles on the second route that the approaching vehicle system is approaching the crossing along the first route; wherein the one or more arrival times are determined at different respective locations along the first route as the approaching vehicle system travels toward the crossing. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A system comprising:
-
a remote crossing system configured to activate one or more warning devices disposed at or near a crossing between a first route being traveled by an approaching vehicle system and a second route to notify other vehicles on the second route that the approaching vehicle system is approaching the crossing along the first route, the remote crossing system configured to receive plural notification messages from the approaching vehicle system, the notification messages including one or more arrival times of the approaching vehicle system that represent when the approaching vehicle system is expected to arrive at the crossing and that are determined at two or more different locations along the first route, wherein the remote crossing system is configured to activate the one or more warning devices responsive to at least one of the arrival times being within a designated warning time of the remote crossing system. - View Dependent Claims (16, 17)

18. A method comprising:
-
receiving plural notification messages from an approaching vehicle system at a remote crossing system configured to activate one or more warning devices disposed at or near a crossing between a first route being traveled by the approaching vehicle and a second route to notify other vehicles on the second route that the approaching vehicle system is approaching the crossing along the first route, the notification messages including one or more arrival times of the approaching vehicle system that represent when the approaching vehicle system is expected to arrive at the crossing and that are determined at two or more different locations along the first route; and activating the one or more warning devices responsive to at least one of the arrival times being within a designated warning time of the remote crossing system. - View Dependent Claims (19, 20)
