VARIABLE AIR-PRESSURE VALUE DETERMINATION METHOD FOR A VEHICLE AIR TYRE, AS WELL AS A PRESSURE VALUE INDICATION METHOD

摘要

1. Method of determining a variable air pressure value of a pneumatic vehicle tyre, wherein an information signal, which is dependent on a measured value transmitter, is transmitted to a measured value receiver, the signal is compared with existing desired values, at least for the air pressure, in an evaluation circuit or evaluation electronics, a value deviation is determined, and an air pressure state corresponding to the measured value is indicated, characterised in that the information signal is compared with a plurality of predetermined, but selectable, desired value curves (S) which are each dependent on a mean value (Ta ) for the external temperature of the tyre, which value is present for a selectable time interval, and the desired value curves have a respectively associated tolerance range (Stol ), and accordingly the information signal determines at least one deviation in the air pressure of the tyre, and this deviation is associated with a predetermined air pressure state of the tyre depending on the desired value curve tolerance ranges, and at least the actual air pressure state of the pneumatic vehicle tyre is indicated.
