SYSTEMS AND METHODS FOR PRESERVING ROUTE INSTRUCTION INFORMATION

Abstract:

A system includes one or more processors configured to be disposed onboard a vehicle. When in an active state of the vehicle in which the system receives instructions from an off-board system, the one or more processors receive enforcement targets from an off-board source. The enforcement targets are associated with corresponding portions of a route, and have corresponding associated enforcement activities to be performed based on location of the vehicle relative to the corresponding portions of the route. The one or more processors are also configured to store at least some of the received enforcement targets onboard the vehicle as preserved targets having corresponding preserved enforcement activities, responsive to a transition from the active state to a degraded state of the vehicle in which the enforcement targets are no longer received. Also, the one or more processors are configured to perform the preserved enforcement activities associated with the preserved targets.
