    摘要： Method for the indirect tire pressure monitoring in which there are performed a rolling circumference analysis of the tires, in which rolling circumference analysis variables (ΔDIAG, ΔSIDE, ΔAXLE) are determined from actually found and learnt test variables describing the rotation of the wheels, and a frequency analysis of the natural oscillation behavior of at least one tire in which at least one frequency analysis variable (fk) is determined, in which case an evaluation of the rolling circumference analysis (A) and the natural frequency analysis (C) and a combined evaluation (B) of both methods of analysis is performed for warning indication of tire pressure loss.

    摘要： Method for the indirect tire pressure monitoring in which an analysis of the natural oscillation behavior of at least one tire is performed and at least one pressure loss analysis variable (fFL, fFR, fRL, fRR), in particular a natural frequency, is determined, in which case a temperature compensation (4) of the pressure loss analysis variable (fFL, fFR, fRL, fRR) is performed, and in which case a tire temperature (Ttire) calculated by means of a temperature model (1) is used to determine a compensation quantity (2), in particular the quotient of variation of the pressure loss analysis variable and change in temperature.
