Claim:
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.
