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.
Claims28
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.
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).
The system as recited in one of the preceding claims,
- wherein the information represents the slip requirement of the tire (12).
The system as recited in one of the preceding claims,
- wherein the information represents the maximum allowed vehicle longitudinal speed for the tire (12).
The system as recited in one of the preceding claims,
- wherein the information represents the manufacturing date of the tire (12).
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.
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.
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.
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.
The system as recited in one of the preceding claims,
- wherein it is possible to output driver information as a function of the information.
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.
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.
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).
Dependencies are inferred from the claim text.
