SYSTEM AND METHOD FOR PREDICTING FAILURE OF A WHEEL BEARING IN VEHICLE
First Claim
1. A method for predicting potential failure of a wheel bearing in a vehicle, comprising:
- operating the vehicle for a time period;
measuring a temperature value for the wheel bearing after the time period;
comparing the temperature value to a threshold value for the wheel bearing; and
providing an indication of potential failure of the wheel bearing when the temperature value exceed the threshold value.

Abstract
Methods and apparatus are provided for predicting potential failure of wheel bearings in a vehicle. The apparatus includes a temperature sensor configured to measure a temperature value for a wheel bearing and a processor for comparing the temperature value to a threshold value. When the temperature value exceeds the threshold value, the process provides an indication to warn of the potential failure of the wheel bearing. The method includes operating the vehicle for a time period and measuring a temperature value for the wheel bearing after the time period. Next, the temperature value is compared to a threshold value for the wheel bearing. When the wheel bearing temperature value exceeds the threshold value, and indication is provided to warn of the potential failure of the wheel bearing.

8. A method for predicting potential failure of wheel bearings in a vehicle, comprising:
-
operating the vehicle for a time period; measuring a first temperature value for a first wheel bearing after the time period; measuring a second temperature value for a second wheel bearing after the time period; subtracting the first temperature value from the second temperature value to provide a difference value; comparing the difference value to a threshold value; when the difference value exceeds the threshold value, comparing the first temperature value and second temperature to determine which of the first and second wheel bearing has a potential to fail and providing an indication of potential failure of the first or second wheel bearing; and when the difference value does not exceed the threshold value, comparing the first temperature value to the threshold value to determine whether the first wheel bearing has a potential to fail and comparing the second temperature value to the threshold value to determine whether the second wheel bearing has a potential to fail and providing an indication of potential failure of the first or second wheel bearing when a respective temperature value exceeds the threshold value. - View Dependent Claims (9, 10, 11, 12, 13, 14)
