Abstract

A system for monitoring the properties of at least one tire (12) on a vehicle (36) is described, means being provided on the tire to store information representing properties of the tire (12) and sensors (20, 22) being provided for acquiring the information. A method for monitoring properties of at least one tire is also described.

Claims

1. A system for monitoring properties of at least one tire (12) on a vehicle (36),

wherein

means are provided for storing information on the tires, the information representing properties of the tire (12), and

sensors (20, 22) are provided for acquiring the information.

2. The system as recited in claim 1,

wherein the driving response of the vehicle (36) is controlled based on the information acquired by the sensors (20, 22).

3. The system as recited in claim 1 or 2,

wherein the driving response of the vehicle (36) is regulated based on the information acquired by the sensors (20, 22).

4. The system as recited in one of the preceding claims,

wherein

means for storing the information are implemented by modifying the acquiring elements (24, 26, 28, 30) of a tire sensor situated on the tires (12) and

a vehicle dynamics control system (16) is provided to evaluate the information, the vehicle dynamics control system processing the information from tire sensors (20, 22).

5. The system as recited in one of the preceding claims,

wherein the information represents the slip requirement of the tire (12).

6. The system as recited in one of the preceding claims,

wherein the information represents the maximum allowed vehicle longitudinal speed for the tire (12).

7. The system as recited in one of the preceding claims,

wherein the information represents the manufacturing date of the tire (12).

8. The system as recited in one of the preceding claims,

wherein it is possible to determine if the tire (12) is approved for the vehicle as a function of the information.

9. The system as recited in one of the preceding claims,

wherein it is possible to determine the tire wear as a function of the information.

10. The system as recited in one of the preceding claims,

wherein it is possible to activate a speed limiting device as a function of the information.

11. The system as recited in one of the preceding claims,

wherein it is possible to activate a vehicle immobilizing device as a function of the information.

12. The system as recited in one of the preceding claims,

wherein it is possible to output driver information as a function of the information.

13. The system as recited in one of the preceding claims,

wherein a memory unit affixed to the tire (12) is provided for storing the information.

14. The system as recited in one of the preceding claims,

wherein

an applicable service life model of the tire (12) is inferred from the information,

values of variables which influence the life of the tire (12) are acquired during the life of the tire (12),

the values are used as input values for the service life model and

the service life model is used to decide if the tire has exceeded its service life.

15. A method for monitoring properties of at least one tire (12) on a vehicle (36),

wherein

information is stored on the tire, the information representing information of the tire (12) and

the information is acquired by sensors (20, 22).

16. The method as recited in claim 15,

wherein the driving response of the vehicle (36) is controlled based on the information acquired by the sensors (20, 22).

17. The method as recited in claim 15 or 16,

wherein the driving response of the vehicle (36) is regulated based on the information acquired by the sensors (20, 22).

18. The method as recited in one of claims 15 through 17,

wherein

the information is stored by modifying the acquiring elements (24, 26, 28, 30) of a tire sensor situated on the tire and

the information is evaluated within a vehicle dynamics control system (16) which processes the information from tire sensors (20, 22).

19. The method as recited in one of claims 15 through 18,

wherein the information represents the slip requirement of the tire (12).

20. The method as recited in one of claims 15 through 19,

wherein the information represents the maximum allowed vehicle longitudinal speed for the tire (12).

21. The method as recited in one of claims 15 through 20,

wherein the information represents the manufacturing date of the tire (12).

22. The method as recited in one of claims 15 through 21,

wherein it is possible to determine if the tire (12) is approved for the vehicle as a function of the information.

23. The method as recited in one of claims 15 through 22,

wherein it is possible to determine the tire wear as a function of the information.

24. The method as recited in one of claims 15 through 23,

wherein it is possible to activate a speed limiting device as a function of the information.

25. The method as recited in one of claims 15 through 24,

wherein it is possible to activate a vehicle immobilizing device as a function of the information.

26. The method as recited in one of claims 15 through 25,

wherein it is possible to output driver information as a function of the information.

27. The method as recited in one of claims 15 through 26,

wherein the information is stored in an electronic memory unit affixed to the tire (12).

28. The method as recited in one of claims 15 through 27,

wherein

an applicable service life model of the tire (12) is inferred from the information,

values of variables which influence the life of the tire (12) are acquired during the life of the tire (12),

the values are used as input values for the service life model and

the service life model is used to decide if the tire has exceeded its service life.
