SYSTEM AND METHOD FOR DETERMINING A MISMATCH BETWEEN A MODEL FOR A POWERED SYSTEM AND THE ACTUAL BEHAVIOR OF THE POWERED SYSTEM
First Claim
1. A system for determining a mismatch between a model for a powered system and the actual behavior of the powered system, said system comprising:
- a coupler positioned between adjacent cars of said powered system, said respective coupler being positioned in one of a stretched slack state and a bunched slack state based upon the separation of said adjacent cars; and
a controller positioned within said powered system, said controller is configured to determine a mismatch of said model.

Abstract
A system is provided for determining a mismatch between a model for a powered system and the actual behavior of the powered system. The system includes a coupler positioned between adjacent cars of the powered system. The coupler is positioned in a stretched slack state or a bunched slack state based upon the separation of the adjacent cars. The system further includes a controller positioned within the powered system. The controller is configured to determine a mismatch of the model. A method is also provided for determining a mismatch between a model for a powered system and the actual behavior of the powered system.

20. A system for determining a mismatch between a model for a powered system and the actual behavior of the powered system, said system comprising:
-
a speed sensor positioned within said powered system to measure a speed of said powered system; and a controller positioned within said powered system, said controller being coupled to said speed sensor, said controller including a memory configured to store a speed pattern of said powered system for a fixed time during a past mismatch of the model; said controller is configured to compare data of said speed of the powered system received from said speed sensor with said speed pattern to determine a mismatch of said model. - View Dependent Claims (21, 22)

24. A system for determining a mismatch between a model for a powered system and the actual behavior of the powered system, said system comprising:
-
a speed sensor positioned within said powered system to measure a speed of said powered system; and a controller positioned within said powered system and coupled to said speed sensor, said controller configured to determine an acceleration from said data of the speed of said powered system and determine whether the time rate of change of said acceleration of said powered system exceeds a predetermined threshold over a predetermined time period stored in a memory of said controller. - View Dependent Claims (25, 26)

27. A method for determining a mismatch between a model for a powered system and the actual behavior of the powered system, said method comprising:
-
measuring a speed of said powered system; measuring a current notch of an engine of said powered system; determining a stability state of said powered system based on a collective separation of adjacent cars of said powered system; determining a jerk of said powered system equal to a time rate of change of the acceleration of said powered system based on said speed; and determining a mismatch of said model based upon at least two of said jerk, current notch, and powered system stability state being modified by a respective threshold within a real-time predetermined time period.
