Wheel End Condition Detection
First Claim
1. A non-transitory computer-readable storage medium having computer-executable program instructions stored thereon that when executed by a processor cause the processor to perform steps comprising:
- (i) receiving tire air temperature data of a vehicle;
(ii) receiving a message with at least one antilock brake system (ABS) wheel speed sensor fault code of the vehicle;
(iii) analyzing the tire air temperature data to determine when the tire air temperature data indicates that at least one of a plurality of tires associated with the vehicle exhibits a tire air temperature above a first predetermined threshold;
(iv) when the tire air temperature data indicates that the at least one of a plurality of tires associated with the vehicle exhibits the tire air temperature above the first predetermined threshold, analyzing the message to determine when the at least one antilock brake system (ABS) wheel speed sensor fault code in the message corresponds to a wheel end associated with the at least one of the plurality of tires; and
(v) when the at least one antilock brake system (ABS) wheel speed sensor fault code in the message corresponds to the wheel end associated with the at least one of the plurality of tires, initiating at least one of a shutdown or derate procedure for the vehicle.

Abstract
An enhanced wheel data processing unit may analyze tire air temperature data from a tire pressure monitoring system (TPMS) and antilock brake system (ABS) wheel speed sensor fault codes from an ABS controller within a vehicle. When the enhanced wheel data processing unit determines that the tire air temperature is above a predetermined threshold for a given tire and that an ABS wheel speed sensor fault code exists for the wheel end corresponding to the same tire, the enhanced wheel data processing unit may initiate a vehicle shutdown or derate procedure. The vehicle shutdown or derate procedure may include instructions to give an operator of the vehicle a warning indicator for a predetermined time period before shutting down or derating the engine power to the vehicle.
