Abstract

A system and method for using Radio Frequency IDentification (RFID) tags to monitor tire tread wear in vehicles. A Radio Frequency IDentification chip is embedded in a tread of a tire at a radial depth of allowable tire tread wear specified by a manufacturer of the tire. Responsive to embedding the Radio Frequency IDentification chip in the tread, the presence of the Radio Frequency IDentification chip may be detected by polling the Radio Frequency IDentification chip for a signal. If the Radio Frequency IDentification reader fails to detect the signal of the Radio Frequency IDentification chip, a notification that the tire should be replaced is provided.

Claims

1. A computer implemented method for monitoring tire tread wear on a vehicle, the computer implemented method comprising:

embedding a Radio Frequency IDentification chip in a tread of a tire at a radial depth of allowable tire tread wear specified by a manufacturer of the tire;

responsive to embedding the Radio Frequency IDentification chip in the tread, detecting a presence of the Radio Frequency IDentification chip by polling the Radio Frequency IDentification chip for a signal; and

responsive to a failure of a Radio Frequency IDentification reader to detect the signal of the Radio Frequency IDentification chip, providing a notification recommending that the tire be replaced.

2. The computer implemented method of claim 1, wherein the notification includes one of an visual or audible alert to a driver of the vehicle, a log of an error condition to a computer of the vehicle, an alert to a service facility, or an alert to a central dispatch or control facility.

3. The computer implemented method of claim 1, wherein providing a notification further comprises performing at least one of an action to disable the starter motor of the vehicle or an action to activate a speed regulator in the vehicle to control the maximum speed of the vehicle.

4. The computer implemented method of claim 1, further comprising:

responsive to replacement of the tire with a new tire, resetting the Radio Frequency IDentification reader to detect a new Radio Frequency IDentification chip embedded within the new tire.

5. The computer implemented method of claim 1, wherein the tread comprises multiple Radio Frequency IDentification chips embedded at various depths within the tread.

6. The computer implemented method of claim 5, wherein the various depths at which the Radio Frequency IDentification chips are embedded determines a type or severity of the notifications provided.

7. A system for monitoring tire tread wear on a vehicle, the system comprising:

a tire;

a Radio Frequency IDentification chip embedded within a tread of the tire, wherein the Radio Frequency IDentification chip is embedded at a radial depth of allowable tire tread wear specified by a manufacturer of the tire; and

a Radio Frequency IDentification reader, wherein the Radio Frequency IDentification reader detects a presence of the Radio Frequency IDentification chip by polling the Radio Frequency IDentification chip for a signal, and wherein the Radio Frequency IDentification reader provides a notification recommending that the tire be replaced in response to a failure of the Radio Frequency IDentification reader to detect the signal of the Radio Frequency IDentification chip.
