1. A method of determining that a failure has occurred at or in a wheel end bearing of a vehicle, the method comprising:
calculating, using a processing circuitry, an estimated value of a temperature of the wheel end bearing based on operating conditions of the wheel end bearing,
acquiring, using a temperature sensor, a measured value of the temperature of the wheel end bearing,
comparing, using the processing circuitry, the measured value with the estimated value, and
determining, using the processing circuitry, that the failure has occurred when the measured value deviates from the estimated value by at least a predefined difference.
