Abstract

A method for measurement, storage and provision of key tire data, uses sensors assigned to the individual tires, tire electronics units assigned to each tire, and a vehicle-side control unit in which all key tire data measured over the period of the use of a tire will be stored in an electrical memory unit of the associated tire electronics unit, with the tire electronics unit arranged on each tire a current tire mileage performance is determined, added to the existing, stored overall mileage performance and stored as new overall mileage performance in the memory unit, with a transmission unit arranged at each tire the stored key tire data and the overall mileage performance are transmitted to the vehicle-side evaluation unit, and the energy required for operation of the tire is obtained in each case from energy generators each assigned to a tire.

Claims

1. A method for measurement, storage and provision of key tire data, using

sensors assigned to the individual tires,

tire electronics units assigned to each tire, and

a vehicle-side control unit,

the method comprising the steps of:

storing all key tire data measured over the period of the use of a tire in an electrical memory unit of the associated tire electronics unit,

with the tire electronics unit arranged on each tire, determining a current tire mileage performance, adding the current tire mileage performance to an existing stored overall mileage performance and storing a result of said adding as new overall mileage performance in the memory unit,

with a transmission unit arranged at each tire, transmitting the stored key tire data and the overall tire mileage performance to a vehicle-side evaluation unit,

and obtaining the energy required for operation of the tire electronics units from respective energy generators each assigned to a tire.

2. A method according to claim 1, wherein, when the key tire data is measured, a tire pressure, a tire temperature, a tire speed and a time assigned to the tire speed of each tire will be measured.

3. A method according to claim 1, wherein the tire mileage performance is determined from a tire speed and an assigned time interval of each tire.

4. A method according to claim 1, wherein a warning signal is displayed in a motor vehicle if a defined overall mileage performance of a tire is exceeded.

6. A method according to claim 1, wherein, when the key tire data is measured, a tire pressure, a tire temperature, a tire speed and a time assigned to the tire speed of each tire will be measured.

7. A method according to claim 1, wherein the tire mileage performance is determined from a tire speed and an assigned time interval of each tire.

8. A method according to claim 1, wherein a warning signal is displayed in a motor vehicle if a defined overall mileage performance of a tire is exceeded.

10. A tire according to claim 1, comprising means to measure a tire pressure, a tire temperature, a tire speed and a time assigned to the tire speed of the tire.

11. A tire according to claim 1, wherein the tire mileage performance is determined from a tire speed and an assigned time interval of each tire.

12. A vehicle comprising a tire according to claim 1, comprising means to display a warning signal if a defined overall mileage performance of a tire is exceeded.

5. A method for measurement, storage, and provision of key tire data of a motor vehicle tire, the method comprising the steps of:

storing all key tire data measured over the period of the use of a tire in a memory unit in said tire,

determining a current tire mileage performance,

adding the current tire mileage performance to an existing stored overall mileage performance and storing a resulting new overall mileage performance in the memory unit,

transmitting the stored key tire data and the overall tire mileage performance to a vehicle-side evaluation unit,

and obtaining the energy required for operation of the memory unit from an energy generator within said tire.

9. A motor vehicle tire, comprising:

an electronic unit comprising a memory unit for storing all key tire data measured over the period of the use of a tire,

means for determining a current tire mileage performance,

means for adding the current tire mileage performance to an existing stored overall mileage performance and for storing a resulting new overall mileage performance in the memory unit,

a transmitter coupled with said electronic unit for transmitting the stored key tire data and the overall tire mileage performance to a vehicle-side evaluation unit,

an energy generator within said tire coupled with said electronic unit.
