1. A method comprising:
- determining first rotational speeds of a wheel of a vehicle using a rotational speed sensor;
determining a baseline wheel rotational speed of the wheel, the baseline wheel rotational speed representing one or more of an average or filtered rotational speed of the wheel based on second rotational speeds of the wheel that previously were measured;
identifying one or more differences between the first rotational speeds and the baseline wheel rotational speed;
correlating the one or more differences between the first rotational speeds and the baseline wheel rotational speed with different segments of an outer perimeter of the wheel by temporally matching when the first rotational speeds associated with the one or more differences were measured and when the different segments of the outer perimeter of the wheel were in contact with a route on which the vehicle is moving;
identifying one or more of damage to the wheel or damage to a drivetrain of the vehicle based at least in part on the one or more differences being correlated with the one or more segments of the outer perimeter of the wheel; and
changing movement of the vehicle responsive to identifying the one or more of the damage to the wheel or the damage to the drivetrain.

Abstract
Systems and methods for monitoring a vehicle determine a baseline wheel rotational speed and wheel rotational speeds of a wheel for different positions along an outer perimeter of the wheel. One or more deviations between the wheel rotational speeds and the baseline wheel rotational speed are determined, and the deviations between the wheel rotational speeds and the baseline wheel rotational speed are correlated with one or more identified positions of the positions along the outer perimeter of the wheel. One or more of damage to the wheel or damage to a drivetrain of the vehicle is identified based at least in part on the one or more deviations being correlated with the one or more identified positions.

16. A system comprising:
-
one or more processors configured to receive first rotational speeds of a wheel of a vehicle from a rotational speed sensor, the one or more processors configured to determine a baseline wheel rotational speed of the wheel, the baseline wheel rotational speed representing one or more of an average or a filtered rotational speed of the wheel based on second rotational speeds of the wheel that were previously measured, the one or more processors also configured to identify one or more differences between the first rotational speeds and the baseline wheel rotational speed, and to correlate the one or more differences between the first rotational speeds and the baseline wheel rotational speed with different segments of an outer perimeter of the wheel by temporally matching when the first rotational speeds associated with the one or more differences were measured and when the different segments of the outer perimeter of the wheel were in contact with a route on which the vehicle is moving, wherein the one or more processors also are configured to identify one or more of damage to the wheel or damage to a drivetrain of the vehicle based at least in part on the one or more differences being correlated with the one or more identified segments of the outer perimeter of the wheel, wherein the one or more processors also are configured to change movement of the vehicle responsive to identifying the one or more of the damage to the wheel or the damage to the drivetrain. - View Dependent Claims (17, 18)

19. A method comprising:
-
determining rotational speeds of a wheel during movement of a vehicle that includes the wheel along a route; determining different locations along the wheel that contact the route as the rotational speeds are measured; determining one or more of the rotational speeds of the wheel that exceed a baseline rotational speed of the wheel; determining one or more groups of the locations along the wheel that correspond with the one or more rotational speeds of the wheel that exceed the baseline rotational speed; determining one or more of damage to the wheel, a flat portion of the wheel, or damage to a drivetrain of the vehicle based at least in part at least one of the groups of the locations including at least a designated, non-zero threshold number of the locations along the wheel that correspond with the one or more rotational speeds of the wheel that exceed the baseline rotational speed; and changing movement of the vehicle responsive to determining the one or more of damage to the wheel, the flat portion, or the damage to the drivetrain. - View Dependent Claims (20)
