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.
Claims20
A system comprising:
- a controller configured to be positioned within a powered vehicle of a powered system that includes a train having a coupler between adjacent cars of the powered system, the coupler configured to be positioned in a slack state that includes one of a stretched slack state or a bunched slack state based on separation of the adjacent cars, the controller also configured to determine a mismatch of a model of the slack state for the coupler of the powered system and a current, actual slack state of the coupler on a real time basis from a plurality of input parameters including at least one of a powered vehicle parameter, a track parameter, a train parameter, or a train stability state, the controller further configured to determine a corrective action that reduces the mismatch between the model of the slack state and the current, actual slack state of the coupler,
- wherein the train travels on a rail along a predetermined route, and the controller is configured to switch from a manual mode in which a powered vehicle operator is configured to manually input the corrective action to an automatic mode in which the controller is configured to automatically implement the corrective action for a predetermined amount of time.
A system comprising:
- a controller configured to be positioned within a powered vehicle of a vehicle system having plural units coupled with each other by couplers, the controller configured to compare a current, actual slack state of the vehicle system with a model of the slack state of the vehicle system during actual travel of the vehicle system along a route in order to identify a mismatch between the model and the current, actual operations, wherein the controller is configured to automatically change at least one of a throttle setting or a brake setting to reduce the mismatch between the model of the slack state and the current, actual slack state when the mismatch is identified.
