  • Publication number: 20200234513
    Abstract: An automatic fault isolation and diagnosis system includes a cloud-based data system having multiple machine-readable troubleshooting procedures stored therein. A vehicle fault code is generated by one of multiple vehicle control devices of a vehicle platform. The fault code defines an issue with at least one system or component of the vehicle platform. A data transfer device within the vehicle platform receives the fault code and forwards the fault code to the cloud-based data system. The fault code is received and analyzed in the cloud-based data system to initially determine if the fault code is directed to and can be automatically corrected by one of the stored machine-readable troubleshooting procedures.

  • Publication number: 20200149993
    Abstract: A machine bearing disposed on a rotatable member, such as may be present on a vehicle, is described. A method for monitoring a state of health of the machine bearing includes monitoring, via a microphone, an acoustic signal, and coincidently determining a rotational speed of the rotatable member associated with the machine bearing. The sound spectrum is correlated to the rotational speed of the rotating member, and a time-frequency analysis is executed to determine a sound spectrum. The sound spectrum is transformed to a residual spectrum. A first feature associated with a first frequency band and a second feature associated with a second frequency band are extracted from the residual spectrum. The state of health associated with the machine bearing is detected based upon the first and second features, and is communicated to a second controller.
