Abstract:
A method for early detection and prognosis of wheel bearing faults in a motor vehicle includes one or more of the following: obtaining a wheel speed of a wheel with a sensor in combination with an encoder ring, the sensor generating a signal, the wheel including a bearing that enables rotational movement of the wheel; pre-processing the signal from the sensor; and post- processing an output of the pre-processed signal to generate a bearing fault signature of the bearing.
