A puncture detection system for a tire, comprising:
- a camera configured to be mounted in a wheel well of a vehicle, the camera being capable of detecting light reflected from a foreign object in the tire;
- a proximity sensor;
- and
- a processor in communication with the camera and the proximity sensor, the processor programmed to transmit an alert when the camera detects periodic reflected light from a foreign object in the tire.
An electromagnetic puncture detection system for a vehicle having at least one wheel and at least one tire including a belt, the system comprising:
- a transducer,
- wherein the transducer is sensitive to a magnetic field created by a magnetic field source when the tire is in motion and outputs an electric signal corresponding to the magnitude of the magnetic field;
- and
- a processor configured to receive the signal sent from the transducer and transmit an alert when the magnetic field varies outside of a predetermined threshold.
A method for detecting a puncture in a tire comprising the steps of:
- sensing the presence of a foreign object embedded in a tire;
- measuring the rotations of the tire;
- tracking whether the foreign object remains in the tire for a pre-determined number of tire rotations;
- and
- alerting a driver of the presence of the foreign object if the pre-determined number of rotations is reached or surpassed.
