Rail vehicle signal enforcement and separation control
First Claim
1. A system for evaluating vehicle operation compliance, wherein the system comprises:
- a control signal interface subsystem; and
a vehicle-mounted subsystem configured to;
communicate with the control signal interface subsystem to receive information corresponding to a status of a control signal;
determine a rule for behavior of a vehicle according to the information corresponding to the status of the control signal; and
observe operation of the vehicle to evaluate compliance with the rule;
wherein;
the control signal interface subsystem comprises an ultra-wideband (UWB) communications component;
the vehicle-mounted subsystem comprises an ultra-wideband (UWB) communications component; and
the vehicle-mounted subsystem and the control signal interface subsystem are further configured to communicate UWB signals carrying data pertinent to evaluating vehicle operation compliance, the data comprising at least one of;
a unique ID associated with the vehicle-mounted subsystem, a signal indication, a track number, a track direction, speed, and direction of travel.

Abstract
A system for vehicle management includes a control signal interface subsystem and a vehicle-mounted subsystem. Each of these subsystems includes an ultra-wideband (UWB) communications component. The subsystems communicate with each other through the UWB components. The vehicle mounted subsystem interfaces with a braking system of the vehicle. The vehicle mounted subsystem determines the distance between it and the control signal interface subsystem based on the time-of-flight of at least one communication between the subsystems. The vehicle-mounted subsystem can cause the braking system of the vehicle to activate if the distance between the vehicle-mounted subsystem and the control signal interface subsystem is less than a threshold.
