Abstract: Systems and methods for examining a route inject one or more electrical examination signals into a conductive route from onboard a vehicle system traveling along the route, detect one or more electrical characteristics of the route based on the one or more electrical examination signals, apply a filter to the one or more electrical characteristics, and detect a break in conductivity of the route responsive to the one or more electrical characteristics decreasing by more than a designated drop threshold for a time period within a designated drop time period. Feature vectors may be determined for the electrical characteristics and compared to one or more patterns in order to distinguish between breaks in the conductivity of the route and other causes for changes in the electrical characteristics.

Abstract: A system and method control a powered system having an engine configured to operate using a plurality of fuel types. A first set of control signals including a first set of valve signals are communicated to each fuel tank based at least in part on a first stored engine operating profile to control amounts of fuel provided from each fuel tank to the engine. A different, second set of control signals including a second set of valve signals are communicated to the fuel tanks based at least in part on a second stored engine operating profile to control or change the amounts of fuel from each fuel tank to the engine. The system and method can switch between operating conditions associated with different external domains to alter the engine operating profile used to control the fuel or fuels supplied to the engine.

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: A method for controlling a vehicle system includes determining a vehicle reference speed using an off-board-based input speed and an onboard-based input speed. The off-board-based input speed is representative of a moving speed of the vehicle system and is determined from data received from an off-board device. The onboard-based input speed is representative of the moving speed of the vehicle system and is determined from data obtained from an onboard device. The method includes using the vehicle reference speed to at least one of measure wheel creep for one or more wheels of the vehicle system or control at least one of torques applied by or rotational speeds of one or more motors of the vehicle system.

Abstract: A system and method for detecting movement of a vehicle and/or for changing operating modes of the vehicle switch between transitional operating mode of the vehicle at a first vehicle speed and a moving mode of the vehicle at a second vehicle speed. Movement of the vehicle is controlled to maintain a speed and/or location of the vehicle within designated limits during operation of the vehicle in the transitional operating mode. Movement of the vehicle is controlled to keep an operating parameter of the vehicle below a designated limit during operation of the vehicle in the moving mode. The vehicle switches between the transitional operating mode and the moving mode based at least in part on the vehicle speed, a distance from the target stopping location, an environmental condition, a vehicle characteristic, and/or a route occupancy condition.

Abstract: Methods and systems detect short circuits in an electrical system, such as a dynamic braking grid of a vehicle. The methods and system measure a characteristic of a current that is conducted through one or more resistive elements of an electrical system. The current is supplied to the electrical system from a power source as an applied voltage. A resistance change signal representative of a change in one or more electrical resistances of the one or more resistive elements is determined The resistance change signal can be based at least in part on a difference between the characteristic of the current that is measured and a low pass filtered value of one or more of the characteristic of the current that is measured or the applied voltage supplied by the power source. A short circuit event is identified based at least in part on the resistance change signal.

Abstract: A system and method for examining a route and/or vehicle system obtain a route parameter and/or a vehicle parameter from discrete examinations of the route and/or the vehicle system. The route parameter is indicative of a health of the route over which the vehicle system travels. The vehicle parameter is indicative of a health of the vehicle system. The discrete examinations of the route and/or the vehicle system are separated from each other by location and/or time. The route parameter and/or the vehicle parameter are examined to determine whether the route and/or the vehicle system is damaged and, responsive to determining that the route and/or the vehicle is damaged, the route and/or the vehicle system are continually monitored, such as by examination equipment onboard the vehicle system.
