Acoustic signal monitoring system for a tire
First Claim
1. An apparatus for monitoring the condition of a tire comprising:
- at least one sound monitoring device mountable on a vehicle, the sound monitoring device for producing a sound monitoring device output signal representative of the sound produced by at least one tire of the vehicle during rotation of the tire;
a signal processing device comprising a neural network for receiving and processing the sound monitoring device output signal, the signal processing device producing a processing device output signal representative of a potential damage condition of the tire; and
an indication device for receiving the processing device output signal and indicating to a user of the vehicle that the tire is experiencing the potential damage condition .

Abstract
An apparatus for monitoring a condition of a tire, such as tread belt separation, includes at least one sound monitoring device that is carried by a vehicle. The sound monitoring device produces a sound monitoring device output signal that is representative of the sound produced by at least one of the tires during rotation. A signal processing device is also present and includes a neural network. The signal processing device receives and processes the sound monitoring device output signal. A processing device output signal that is representative of a potential damage condition of the tire is produced. An indication device is present and receives the processing device output signal. The indication device informs a user of the vehicle that the tire is experiencing the potential damage condition.
