  • Publication number: 20170174236
    Abstract: A sensor system senses one or more characteristics of vehicles in a vehicle system with sensors disposed onboard the vehicles and communicate data representative of the one or more characteristics from the sensors to one or more of a controller or a control system of the vehicle system. The data communicated from the sensors onboard the same vehicle can be synchronously communicated with respect to the sensors onboard the same vehicle and asynchronously communicated with respect to the sensors disposed onboard one or more other vehicles in the vehicle system. The systems and methods can direct components disposed onboard a vehicle system to change operations, monitor data output by sensors operatively connected with the components, and determine which of the sensors are operatively connected with which of the components based on the operations of the components that are changed and the data that is output by the sensors.

  • Publication number: 20170089446
    Abstract: A vehicle sensor system includes a fluid sensor configured to be disposed onboard a vehicle system and at least partially extend into a gearbox of a traction motor of the vehicle system. The fluid sensor is configured to output data representative of an amount of a lubricating fluid in the gearbox. The system also includes a positioning system configured to output data representative of movement or an absence of movement of the vehicle system, and one or more processors configured to determine the amount of the lubricating fluid in the gearbox based on the data that is output by the fluid sensor responsive to the data output by the positioning system indicating that the vehicle system has not moved or has moved by less than a designated distance for at least a designated, non-instantaneous period of time.

  • Publication number: 20170084094
    Abstract: A sensor system includes one or more sensors that sense vibrations of a vehicle and one or more processors that can determine a speed of the vehicle and determine whether the vibrations occurring at one or more frequencies of interest (that are based on the speed of the vehicle) indicate damage to a propulsion system of the vehicle. The one or more processors optionally may determine a hunting frequency of a wheel and axle set and/or a lateral acceleration of the wheel and axle set from the vibrations. The one or more processors can determine a conicity of a wheel in the wheel and axle set based on the hunting frequency and/or the lateral acceleration that is determined.
