Control system and method
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.
SYSTEM AND METHOD FOR VEHICLE CONTROL BASED ON DETECTED WHEEL CONDITION
A system is provided that includes a detection circuit having a first and second sensor. The first sensor is configured to measure a rotational speed of a first wheel. The second sensor is coupled to a vehicle chassis and configured to measure a position over time of the vehicle chassis. The system further includes a controller circuit configured to determine a shock frequency based on the position of the vehicle chassis. The controller circuit is further configured to determine a condition (e.g., an anomalous condition) of the first wheel based on the shock frequency and the rotational speed, and may be further configured for vehicle control based on the determined condition.
AUTONOMOUS VEHICLE SYSTEM AND METHOD
A system includes a mobile platform that moves under remote and/or autonomous control, a sensor package supported by the mobile platform that obtains information relating to a component of a transportation network, and one or more processors that receive the sensor information and analyze the information in combination with other information that is not obtained from the sensor package. The processors also generate an output that displays information relating to one or more of a status, a condition, and/or a state of health of the component of the transportation network; initiates an action to change an operational state of the component; identifies a hazard to one or more vehicles traveling within the transportation network; and/or collects the information relating to the component. Optionally, the component is not communicatively coupled to an information network and the mobile platform provides the information obtained by the sensor package to the information network.
DOOR SYSTEM WITH SENSOR UNIT AND COMMUNICATION ELEMENT
A door system for a public transit vehicle with at least one door opening and a door that closes this door opening includes a sensor unit, which does three-dimensional and touch-free scanning of a passenger compartment in the area of the door opening and at least one communication element for the context-based communication with passengers based on readings by the sensor unit. A process for monitoring and controlling door systems of a public transit vehicle are also provided including the steps of touch-free and three-dimensional scanning of a passenger compartment in the area of a door opening with a sensor unit and measuring distances, shapes, and movements of objects by evaluating the readings of the touch-free and three-dimensional scanning. The process also includes issuing context-based information to affected passengers via a communications system, whereby the information is based on readings from the sensor unit.
a process for monitoring and controlling such a door system.
LOCOMOTIVE HEALTH-BASED TRAIN PACING SYSTEM
A system for pacing a train having a plurality of locomotives is disclosed. The system may include an signaling system onboard component configured to receive a signal indicative of a requested time of arrival (RTA) of the train, a locomotive health system configured to output one or more health signals indicative of a health status of each of the plurality of locomotives, and an energy management system in electronic communication with the signaling system onboard component and the locomotive health system. The energy management system may be configured to generate driving command signals based on the RTA and the one or more health signals, generate an RTA confirmation signal based on the one or more health signals, the RTA confirmation signal being indicative of whether the train will achieve the RTA, and communicate the RTA confirmation signal to a train signaling system via the signaling system onboard component.
PREVENTION OF COLLISION BETWEEN TRAINS
A system and a method for preventing collision between a first train and a second train are provided. The system includes at least one first subsystem installed on a first train. The at least one first subsystem is configured to broadcast a message indicative of a status of the first train. The system further includes at least one second subsystem installed on a second train configured to selectively receive the broadcast message from the at least one first subsystem on the first train. The second subsystem determines the status of the first train by analyzing the broadcast message. An action to be performed at the second train for preventing a collision between the first train and the second train is determined based on the status of the first train. One or more instructions are generated for performing the action at the second train.
Method and Device for Monitoring an Electric Network in a Rail Vehicle and Rail Vehicle
The invention relates to a device and a method for monitoring an electric network in a rail vehicle. The electric network includes at least one power converter, at least one permanent magnet machine, and at least one first phase line for the electrical connection of the at least one power converter and the at least one permanent magnet machine. The first phase line is interrupted. A potential difference is determined between a machine-side part of the first phase line and a reference potential and a potential-difference-dependent variable, wherein a speed of the permanent magnet machine and, as a function of the speed, a speed-dependent reference variable are determined. A deviation of the potential-difference-dependent variable from the speed-dependent reference variable is determined, wherein a network fault is detected if the deviation is greater than a predetermined threshold value.
Method and system for maintenance of a permanent way for rail vehicles
A method for maintenance of a permanent way, roadway or travel path for rail vehicles includes determining the actual condition of the permanent way by using a measuring system to record measurement data. Objects along the permanent way are detected from the measurement data by using an evaluation device. A detected object is assigned to an object class, and at least one object class identification linked with positional data is stored in a database for a detected object. The actual condition of the permanent way is thus stored in an object-based manner, and a comparison with a target condition or with historic actual conditions is used for the planning and execution of maintenance measures. A maintenance system for executing the method is also provided.
EVENT RECORDER WITH CONFIGURABLE ALARM/EVENT MONITORING
A event recorder system carried on-board a locomotive may include a controller configured to receive data from one or more of a train management system, a cab signaling system, an energy management system, an exhaust aftertreatment monitoring system, a braking system, a communications management system, and an operator fatigue or distraction monitoring system. The data may include one or more of video data, audio data, sensor output data, GPS map data, scanned image data of an operator in a cab of the locomotive, and operational data associated with operation of the locomotive during a trip. The controller may be configured to synchronize the data based on a common attribute associated with all of the data received by the controller, receive from a user one or more customizable parameters predetermined to be indicative of one or more of a system-related characteristic or behavior associated with any one or more of the systems from which the controller receives data, and generate a system notification based on an indication of one or more of a system-related characteristic or behavior that one of falls outside of a predetermined range of system-determinable parameters, or indicates a trend in one or more system-determinable parameters that deviates from an expected trend in the one or more system-determinable parameters.
