ABSTRACT:
The present invention comprises a system for the detection of a pressure drop in a tire. Herein an evaluating unit determines the temporal modification of the temperature in the tire and produces an alerting signal if the temporal modification of the temperature falls short of a predetermined temperature modification threshold value. In presence of an evaluating signal, the evaluating unit determines the temporal modification of the air pressure and produces an alerting signal, if the temporal modification of the air pressure exceeds an air pressure modification threshold value.
