  • Patent number: 10321339
    Abstract: Systems and methods for correlating wireless communication performance with vehicle system configurations determine wireless message characteristics of wireless messages communicated with vehicles in vehicle systems and locations along a route where the wireless message characteristics were determined. The wireless message characteristics and the locations can be determined during movement of the vehicle systems along a route. Consist configuration information about the one or more vehicle systems is obtained, and a signal propagation profile is determined based on the wireless message characteristics, the locations where the wireless message characteristics were determined, and the consist configuration information. The signal propagation profile can represent one or more relationships between the wireless message characteristics, the consist configuration information, and the locations along the route.

  • Patent number: 10078338
    Abstract: Systems and methods for coordinating and controlling vehicles, for example heavy trucks, to follow closely behind each other, or linking to form a platoon. In one aspect, on-board controllers in each vehicle interact with vehicular sensors to monitor and control, for example, relative distance, relative acceleration or deceleration, and speed. In some aspects, vehicle onboard systems supply various data (breadcrumbs) to a Network Operations Center (NOC), which in turn provides data (authorization data) to the vehicles to facilitate platooning. The NOC suggests vehicles for platooning based on, for example, travel forecasts and analysis of relevant roadways to identify platoonable roadway segments. The NOC also can provide traffic, roadway, weather, or system updates, as well as various instructions. In some aspects, a mesh network ensures improved communication among vehicles and with the NOC.

  • Patent number: 9805526
    Abstract: Method and apparatus for calculating probabilities of service interruptions based on fault event indications. Instances of fault event indications are filtered to remove duplicate indications for the same fault event. Then a probability of the fault event indication causing a service interruption is calculated by dividing a number of service interruptions caused by instances of the fault event indication by the number of fault event indications. In the event that a particular fault event indication is associated with a high probability of causing a service interruption, a message can be automatically generated and transmitted upon receipt of a future instance of the service interruption. The message can provide information related to short-term solutions to address the fault event, long-term solutions to address the fault event, and parts and tools for addressing the fault event.

  • Patent number: 9744978
    Abstract: Geo-defect repair modeling is provided. A method includes logically dividing a railroad network according to spatial and temporal dimensions with respect to historical data collected. The spatial dimensions include line segments of a specified length and the temporal dimensions include inspection run data for inspections performed for each of the line segments over a period of time. The method also includes creating a track deterioration model from the historical data, identifying geo-defects occurring at each inspection run from the track deterioration model, calculating a track deterioration condition from the track deterioration model by analyzing quantified changes in the geo-defects measured at each inspection run, and calculating a derailment risk based on track conditions determined from the inspection run data and the track deterioration condition.

  • Patent number: 9731738
    Abstract: A system for vehicle management includes a control signal interface subsystem and a vehicle-mounted subsystem. Each of these subsystems includes an ultra-wideband (UWB) communications component. The subsystems communicate with each other through the UWB components. The vehicle mounted subsystem interfaces with a braking system of the vehicle. The vehicle mounted subsystem determines the distance between it and the control signal interface subsystem based on the time-of-flight of at least one communication between the subsystems. The vehicle-mounted subsystem can cause the braking system of the vehicle to activate if the distance between the vehicle-mounted subsystem and the control signal interface subsystem is less than a threshold.

  • Patent number: 9714042
    Abstract: Train position is sensed using a position sensing unit having plurality of position sensors arrayed in the direction of train travel. The sensors respond to the presence and absence of a detection element on each train car, the detection element being longer than the spacing between adjacent position sensors. A confirmed count of a train car passing the position sensing unit requires detection of a series of related position sensor activations and deactivations. Alternately, the position sensing unit senses data tags on the train cars, reading unique identifiers therefrom. A list of identifiers corresponding to the car order is stored and compared to the identifiers read in order to determine train position.

  • Patent number: 9646474
    Abstract: During an emergency, a user initiates an emergency trigger, which puts an electronic device into an emergency mode. The device then emits an emergency sound wave having one or more particular characteristics. In one embodiment, the emergency sound wave is inaudible. The device may then emit an audible alert. Nearby devices that detect the emergency sound wave may then, once they validate the emergency sound wave emit their own emergency sound waves, and emit their own audible alerts. This process allows the original alert to be propagated to many devices in the vicinity creating, in effect, a mesh of alerted devices.

The method includes determining a reference fuel/energy consumption, and a cumulative ITE for one, or a plurality of reference train runs (CITERR) over a portion of track, and correcting the reference fuel/energy consumption using the CITERR of the one, or a plurality of reference train runs, to produce a corrected reference fuel/energy consumption value. The operating parameter is modified, and a modified fuel/energy consumption and cumulative ITE for the one, or a plurality of test train runs (CITETR), over the portion of track is determined, and a corrected test fuel/energy consumption value is obtained by correcting the modified fuel/energy consumption using the CITETR of the one, or a plurality of test train runs.

  • Patent number: 9555800
    Abstract: A method of servicing a hybrid system is disclosed wherein the hybrid system includes a detected fault. As a result of the detected fault the hybrid system has been disabled. The hybrid system includes a controller and a service detection interlock (SDI). The method steps include first powering up the controller and then assessing a special fault flag status. If a special fault flag is set, the next step is to check to see if the SDI is removed. If the SDI is removed then the special fault flag is cleared while the hybrid system remains disabled. The controller is then powered down with the key-off input and with the next key-on input, the hybrid system can be enabled.
