A method for checking and/or monitoring the use of a tire (1) mounted on a vehicle (7), comprises the following steps: acquisition, by a microphone (10) arranged inside the tire, of an acoustic response of said tire (1) obtained under the effect of a pulsed mechanical stress thereon, and processing of said response in the frequency domain, characterized in that said processing identifies, in the response in the frequency domain, two spectrum spikes situated on either side of a reference frequency corresponding to the first cavity mode of the tire and, as a function of the frequency deviation between the two duly identified spikes, determines information relating to at least one parameter of use of the tire.

A control subsystem, method and computer program product are provided to detect the failure of a tire of an autonomous vehicle (AV) and to direct a response to the tire failure that has been detected that is appropriate under the circumstances. In this regard, the control subsystem includes processing circuitry configured to receive signals from microphone(s) carried by the AV. The processing circuitry is configured to evaluate signal characteristics of the signals to identify signals indicative of a tire failure. In an instance in which a tire failure is identified, the processing circuitry is configured to determine a type of the tire failure based upon the signal characteristics. The processing circuitry is further configured to determine remedial action to be taken based at least in part upon the type of tire failure. Different remedial actions are determined to be taken for different types of tire failures.

The present invention provides a device for detecting an abnormality in a tire for a light rail with rubber wheels. The detection device is installed inside the auxiliary rim, which is a rigid body mounted on an outer circumferential surface of a wheel, in a rubber tire body, and a protrusion part forming a detection unit of the detection device is configured to protrude into a space inside the rubber tire body. When the tire is punctured, the inner circumferential surface of the rubber tire body comes into close contact with the auxiliary rim, and the protrusion part is pushed into the auxiliary rim to touch the piezoelectric element of the detection unit and generate an electric signal, and thereby transmit a signal for indicating an abnormal condition of the tire to a controller.

The present disclosure is directed to a smart tire puncture feedback system having a camera capable of observing foreign objects embedded in a tire, a proximity sensor, and a processor that can determine how long a foreign object has been embedded in the tire and alert a user after a predetermined period.
