Abstract

A method is provided for storing tire information in a tire sensor. For this purpose, a tire sensor is fastened to a tire having a passive RFID transponder. The RFID transponder is then supplied with energy via an energy field, with the result that the RFID transponder emits the stored tire information. If the tire sensor has determined that the tire sensor is fastened to the tire, the tire information is received and is permanently stored in the tire sensor. The tire information written to a tire sensor is preferably transmitted to the vehicle by the tire sensor and is then taken into account during a movement-dynamic function, for example.

Claims

1. A method for storing tire information in a tire sensor, the method comprising the act of:

fastening a tire sensor to a tire having a passive RFID transponder, the RFID transponder storing tire information;

supplying the RFID transponder with energy, with a result being that the RFID transponder emits tire information;

determining, by the tire sensor, if the tire sensor is fastened to the tire; and

receiving and permanently storing the emitted tire information, directly from the RFID transponder, in the tire sensor itself if the tire sensor has determined that the tire sensor is fastened to the tire.

3. The method according to claim 1, wherein

the tire sensor comprises at least one electrical contact,

an electrical connection is produced via the at least one electrical contact when the tire sensor is fastened to the tire, and

the act of determining if the tire sensor is fastened to the tire is carried out using the electrical connection.

5. The method according to claim 1, further comprising the act of:

introducing the tire sensor into a sensor holder already connected to the tire.

6. The method according to claim 5, wherein the sensor holder already connected to the tire is located on an inside tread of the tire and is adhesively bonded in a ground outlet in the inside tread.

7. The method according to claim 5, wherein the sensor holder already connected to the tire includes the RFID transponder.

11. The method according to claim 1, further comprising the act of:

transmitting, by the tire sensor, the tire information stored in the tire sensor.

2. A method for storing tire information in a tire sensor, the method comprising the act of:

fastening a tire sensor to a tire having a passive RFID transponder, the RFID transponder storing tire information;

supplying the RFID transponder with energy, with a result being that the RFID transponder emits tire information;

determining, by the tire sensor, if the tire sensor is fastened to the tire;

receiving and permanently storing the emitted tire information in the tire sensor if the tire sensor has determined that the tire sensor is fastened to the tire,

deleting the tire information in the tire sensor if the tire sensor has determined that it is not fastened to the tire.

4. The method according to claim 2, wherein

the tire sensor comprises at least one electrical contact,

an electrical connection is produced via the at least one electrical contact when the tire sensor is fastened to the tire, and

the act of determining if the tire sensor is fastened to the tire is carried out using the electrical connection.

8. A method for storing tire information in a tire sensor, the method comprising the act of:

fastening a tire sensor to a tire having a passive RFID transponder, the RFID transponder storing tire information;

supplying the RFID transponder with energy, with a result being that the RFID transponder emits tire information;

determining, by the tire sensor, if the tire sensor is fastened to the tire;

receiving and permanently storing the emitted tire information in the tire sensor if the tire sensor has determined that the tire sensor is fastened to the tire, wherein

the tire sensor is introduced into a sensor holder already connected to the tire,

wherein the tire sensor and the sensor holder each comprise at least one electrical contact,

the electrical contacts of the tire sensor and the sensor holder touch one another when the tire sensor is introduced into the sensor holder, and

an electrical connection is produced by the touching of the electrical contacts, wherein the act of determining if the tire sensor is fastened to the tire is carried out using the electrical connection.

9. The method according to claim 8, wherein the act of introducing the tire sensor into the sensor holder produces a short-circuited connection between two electrical contacts of the tire sensor via an electrical connection that is not within the tire sensor.

10. The method according to claim 9, wherein

the sensor holder includes the RFID transponder, and

an electrical connection is produced between the tire sensor and the RFID transponder when the tire sensor is introduced into the sensor holder.

12. A tire for a motor vehicle, comprising:

a passive RFID transponder that stores tire information;

a tire sensor fastened to the tire, wherein

the RFID transponder is configured to emit the stored tire information when the RFID transponder is supplied with energy,

the tire sensor is configured to determine whether the tire sensor is fastened to the tire, and

the tire sensor is configured to receive, directly from the RFID transponder, the emitted stored tire information from the RFID transponder and to permanently store the information in the tire sensor itself if the tire sensor determines that the tire sensor is fastened to the tire.

13. The tire according to claim 12, further comprising:

a sensor holder configured to receive the tire sensor.

14. The tire according to claim 13, wherein

the sensor holder is fastened on an inside tread of the tire and comprises at least one electrical contact configured for association with a corresponding electrical contact of the tire sensor.

15. The tire according to claim 14, wherein the sensor holder is adhesively bonded in a ground outlet provided in the inside tread of the tire.
