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.

Abstract: Methods and systems are provided for facilitating communications between a vehicle and a trailer. In accordance with one embodiment, a system includes a memory, and a processor, and a transceiver. The memory is disposed onboard a trailer that is configured to be connected to a vehicle. The memory stores trailer-specific information pertaining to the trailer. The processor is disposed onboard the trailer, and is coupled to the memory. The processor is configured to provide instructions to automatically transmit the trailer-specific information to the vehicle, for customization of vehicle operation based on the trailer-specific information. The transceiver is coupled to the processor. The transceiver is configured to automatically transmit, based on the instructions provided by the processor, the trailer-specific information to the vehicle, for customization of vehicle operation based on the trailer-specific information for when the trailer is connected to the vehicle.
