  • Publication number: 20240410786
    Abstract: Vehicles and systems and methods for health monitoring drive unit bearings in vehicles are provided. A system for health monitoring a drive unit bearing in a vehicle includes a sensor mounted to a drive unit of the vehicle and configured to provide a vibration signal; and a processor configured to: pre-process the vibration signal from the sensor to enhance a fault signature and form a frequency domain signal; and process the frequency domain signal to estimate a health stage of the drive unit bearing.

  • Publication number: 20240402317
    Abstract: Systems and methods are provided for controlling a vehicle. In one embodiment, a method includes: receiving, by the controller, return data generated by a lidar device of the vehicle; determining, by the controller, at least one overlapping channel of redundant return data; determining, by the controller, an optimization framework of equations based on modeled errors of the at least one overlapping channel; solving, by the controller, the optimization framework using a least squares method to determine an error value; determining, by the controller, a state of health of the lidar device based on the error value; compensating, by the controller, the return data from the lidar device based on the error value; and controlling, by the controller, the vehicle based on the compensated return data.
