Patent number: 11305602Abstract: A system for testing a suspension system of a vehicle includes an inertial measurement module and a suspension fault detection module. The inertial measurement module is configured to, while the vehicle is not moving, collect sensor data from one or more inertial measurement sensors for different states of the suspension system. The sensor data is indicative of inertial states of the vehicle while the suspension system is in each of the different states. The suspension fault detection module is configured to, based on the sensor data and a set of thresholds, determine whether a fault exists with the suspension system, isolate and identify the fault, and perform a countermeasure based on the detection of the fault.Type: GrantFiled: November 4, 2019Date of Patent: April 19, 2022Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Xinyu Du, Lichao Mai, Brian K. Saylor, Arvind Sharma, Kevin A. Cansiani

Patent number: 11054339Abstract: 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.Type: GrantFiled: November 13, 2018Date of Patent: July 6, 2021Assignee: GM Global Technology Operations LLCInventors: Jianshe Feng, Xinyu Du, Mutasim Salman, Kevin A.
