Abstract
The invention concerns a method and a system for identifying tires of a vehicle, tire pressures of the tires of the vehicle being measured and analysed for the driving-dynamic states of the vehicle with the use of parameters which indicate the driving-dynamic states. Individual tires of the vehicle are unambiguously identified on the basis of the analysis of the measured tire pressures or their variations.
Claims17
Method for identifying a tyre of a vehicle, with the following steps:
- measurement of a tyre pressure of at least one vehicle tyre for at least two different driving-dynamic states of a vehicle,
- comparison of the tyre pressures, for the purpose of determining a tyre pressure variation, and
- analysis of the tyre pressure variation using driving state parameters which characterize the at least two different driving-dynamic states, for the purpose of identifying the vehicle tyre at which the tyre pressures were measured.
System for identifying a tyre of a vehicle, with:
- a device which is located at a tyre of a vehicle for the purpose of measuring tyre pressures,
- a transmitting device which is connected to the device for measuring the tyre pressures, for the purpose of transmitting tyre pressure signals,
- a receiver device for receiving the tyre pressure signals transmitted by the transmitting device,
- a processor device which is connected to the receiver device for the purpose of receiving the tyre pressure signals, and
- at least one device for measuring driving state parameters which characterize the driving-dynamic states of the vehicle, the at least one device for measuring driving state parameters being connected to the processor device for the purpose of transmitting the driving state parameters,
- characterized in that
- the processor device is set up to determine, from the tyre pressure signals, tyre pressure variations for the tyres and to evaluate them using the driving state parameters for driving-dynamic states of the vehicle, for the purpose of identifying the tyre at which the device for measuring the tyre pressures is located.
