Claim Text:
1. A vehicle comprising: the vehicle having a plurality of essentially identical bearings disposed thereon, each of the essentially identical bearings further comprising: a processor disposed in the vehicle that is configured to receive the bearing measurement signals of the sensor in each of the plurality of essentially identical bearings, wherein the processor is configured to use the bearing operation signals in each of the plurality of essentially identical bearings to calculate a standard deviation of the bearing operation conditions measured in all of the plurality of essentially identical bearings such that the standard deviation is related to a variance of the bearing operation conditions measured in all of the plurality of essentially identical bearings at the same point in time, and wherein the processor is further configured to compare the standard deviation to a threshold value, if the standard deviation is greater than the threshold value then the processor is configured to generate a maintenance alert.
