  • Patent number: 9764605
    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.
