Title:
RAIL VEHICLE SIGNAL ENFORCEMENT AND SEPARATION CONTROL
Document Type and Number:
WIPO Patent Application WO/2015/034923
Kind Code:
A3
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.
