Abstract
The system 100 can include: a railroad integration system, a motion planner, a vehicle controller, an optional user interface (UI), an optional fleet management system, and an optional track data system. However, the system 100 can additionally or alternatively include any other suitable set of components. The system functions to facilitate vehicle control and/or manage authority within a rail network.
Claims20
A positive train control (PTC) method comprising:
- at a first computing system, determining a motion plan for an autonomous rail agent based on a set of track rules for a track;
- and
- based on the motion plan and a state of the autonomous rail agent, commanding the autonomous rail agent by broadcasting a first command to the autonomous rail agent;
- and
- maintaining an exclusive track reservation for the autonomous rail agent based on the first command, wherein the exclusive track reservation is dynamically sized;
- and
- at a second computing system:
- autonomously controlling the autonomous rail agent, within the exclusive track reservation, based on the first command;
- and
- providing the state of the autonomous rail agent to the first computing system.

A system for positive train control (PTC) along a track comprising:
- a motion planner configured to:
- determine a motion plan for an autonomous rail vehicle based on a set of track rules of the track;
- based on the motion plan and a state of the autonomous rail vehicle, command the autonomous rail agent by periodically broadcasting commands to the autonomous rail agent;
- and
- maintain an exclusive track reservation for the autonomous rail agent based on the commands, wherein the exclusive track reservation is dynamically determined based on the commands;
- and
- a vehicle controller of the autonomous rail vehicle which is communicatively coupled to the centralized motion planner and configured to:
- autonomously control the autonomous rail vehicle, within the exclusive track reservation, based on the commands;
- and
- provide the state of the autonomous rail vehicle to the centralized motion planner.
