Abstract: An energy management system and method for a vehicle system operate the vehicle system according to a current trip plan as the vehicle system travels along a route during a trip. The current trip plan designates operational settings of the vehicle system. The system and method also revise the current trip plan into a revised trip plan responsive to current, actual operation of the vehicle system differing from the current trip plan by at least a designated threshold amount. The revised trip plan designates operational settings of the vehicle system and includes an initial designated operational setting that matches the current, actual operation of the vehicle system.

Abstract: There is provided a voltage or current sensing device. An exemplary voltage or current sensing device includes a drive circuitry configured to deliver a drive current to a magnetic core operably coupled with a conductor, for driving the core to cyclical magnetic saturation. The device also includes sense circuitry configured to receive a voltage signal corresponding to an application current in the conductor. The device also includes signal processing circuitry configured to sample the voltage signal, wherein a first sample is in phase with the drive current and a second sample is out of phase with the drive current. The device also includes a feedback loop configured to deliver a compensation current to the magnetic core, wherein the compensation current is configured to balance the magnetic core and wherein the compensation current is based at least in part on the first sample in phase with the drive current.

Abstract: A method for controlling a powered system, the method including operating the powered system to perform a mission based on an optimized mission plan, identifying when the powered system is approaching a location in the mission where the powered system may change from a first route to a second route, obtaining information about whether the first route or the second route will be taken, and if the second route is taken, adjusting the mission plan to optimize reduced emissions output and/or reduced fuel consumption based on the route change.

Abstract: A system and method for predicting a route to be authorized by a dispatcher for a vehicle to travel on a route network comprises a computer system that has a database having stored data relative to interconnecting route segments that make up the route network. Data relative to the origination location and the destination location is input into the computer system. The processor accesses the database and generates a predicted route with an origination location and destination location.

Abstract: There is provided a method of determining the state of a signal lamp. The method includes receiving time series data corresponding to an electrical signal used to power a signal lamp. The state of the signal lamp can switch from one of the following states to another of the following states: an on state, an off state, and a flashing state. The method also includes determining the state of the signal lamp, based at least in part on both the time series data and an amplitude value of the electrical signal relative to an amplitude-change threshold value over a determined number of amplitude changes.
