Abstract
A method for determining an operating threshold boundary within which a controller is permitted to control a powered system, the method including calculating a threshold boundary with at least one of information about at least one of a route and a load encountered by the powered system as a function of at least one of time or distance, a characteristic of the powered system, and a characteristics of the controller, and determining whether the powered system exceeds the threshold boundary.

A method for determining an operating threshold boundary within which a controller is permitted to control a powered system, the method comprising:
- calculating a threshold boundary with at least one of information about at least one of a route and a load encountered by the powered system as a function of at least one of time or distance, a characteristic of the powered system, and a characteristics of the controller;
- and
- determining whether the powered system exceeds the threshold boundary.
A computer software code operable within a processor and configured to reside on a computer readable media for determining an operating threshold boundary within which a controller is permitted to control a powered system, the computer software code comprising:
- computer software module for calculating a threshold boundary with at least one of information about at least one of a route and a load encountered by the powered system as a function of at least one of time or distance, a characteristic of the powered system, and a characteristics of the controller;
- and
- computer software module for determining whether the powered system exceeds the threshold boundary.
A method for determining an operating threshold boundary within which an automatic controller is permitted to control a powered system, the method comprising:
- utilizing a power restriction of the controller;
- utilizing a power rate restriction of the controller;
- predicting a speed trajectory between at least one of a current location and a distant location and for each power setting of the powered system;
- determining an overspeed index with the speed trajectory predicted;
- determining a maximum speed with at least one of the power restriction, power rate restriction, a speed limit, a reference speed, a reference power, and the overspeed index;
- and
- determining a maximum speed confidence level with at least one of a distance and a time to reaching the overspeed index and an input parameter.
A method for determining an achievable speed range for a powered system at a future location, the method comprising:
- determining at least one of a location of the powered system and a current power of the powered system;
- identifying a planned speed;
- and
- determining an achievable speed range for a future location with at least one of a maximum power, a minimum power, a maximum power rate, and a minimum power rate.
