1. A method of monitoring a vehicle for wheel related issues, the method comprising:
- measuring, by a plurality of tire pressure monitoring system sensors installed respectively on each of a plurality of tires of a vehicle, temperature data for the plurality of tires;
analyzing, by a processor, the temperature data to determine whether a status of each tire of the vehicle is normal; and
in response to determining that a status for at least one tire of the plurality of tires is not normal, determining, by the processor, whether a wheel related issue is present for the vehicle based at least in part on the temperature data for the at least one tire, and signaling an alarm for an operator regarding the wheel related issue when determined to be present,wherein the wheel related issue comprises at least one of an alignment issue, a brake issue, and a wheel bearing issue, and wherein the wheel related issue does not include issues associated specifically with a tire, including tire pressure and tire wear, andwherein determining whether a wheel related issue is present for the vehicle based at least in part on the temperature data for the at least one tire comprises;
analyzing the temperature data for the at least one tire using a particular model corresponding to each type of wheel related issue, the particular model defined by patterns of temperature data that have been previously associated with at least one of an alignment issue, a brake issue, and a wheel bearing issue, such that the temperature data for the at least one tire can be compared to the patterns of temperature data to identify the wheel related issue when present.

Abstract
A method, apparatus and program product to monitor a vehicle for wheel related issues based at least in part on temperature data collected for tires of the vehicle. Received temperature data for each of a plurality of tires of the vehicle may be received and analyzed to determine whether a status of each tire is normal. Responsive to determining that a status for at least one tire is not normal, wheel related issues present for the vehicle may be detected based at least in part on the temperature data.

7. An apparatus, comprising:
-
a plurality of tire pressure monitoring system sensors installed respectively on each of a plurality of tires of a vehicle, the plurality of tire pressure monitoring system sensors measuring temperature data for the plurality of tires; at least one processor communicating with the plurality of tire pressure monitoring system sensors; and program code configured upon execution by the at least one processor to cause the at least one processor to receive temperature data for each of a plurality of tires of a vehicle, analyze the temperature data to determine whether a status of each tire of the vehicle is normal, and responsive to determining that a status for at least one tire of the plurality of tires is not normal, determine whether a wheel related issue is present for the vehicle based at least in part on the temperature data for the at least one tire, wherein the wheel related issue comprises at least one of an alignment issue, a brake issue, and a wheel bearing issue, and wherein the wheel related issue does not include issues associated specifically with a tire, including tire pressure and tire wear, wherein the program code is configured to cause the at least one processor to determine whether a wheel related issue is present for the vehicle based at least in part on the temperature data for the at least one tire by; analyzing the temperature data for the at least one tire using a particular model corresponding to each type of wheel related issue, the particular model defined by patterns of temperature data that have been previously associated with at least one of an alignment issue, a brake issue, and a wheel bearing issue, such that the temperature data for the at least one tire can be compared to the patterns of temperature data to identify the wheel related issue when present. - View Dependent Claims (8, 9, 10, 11, 12)
