ABSTRACT:
Disclosed is a method of improving the recognition of a tire pressure loss in a tire pressure monitoring system in which at least one reference value (A) is formed on the basis of signals representing the rotational speeds of several vehicle wheels. A pressure loss is concluded by comparing a currently determined reference value with at least one reference value if the currently determined reference value exceeds or falls short of a predefined value. A noise analysis of the reference value(s) (101) is executed and at least one threshold value (T, S) is adjusted (108) based on the result of the noise analysis (102).
