Abstract

A method for indirectly monitoring tire pressure or for detecting damage to a wheel suspension, wherein a pressure loss detection variable (DVE) is determined using an analysis of a vibratory behavior of a wheel of a motor vehicle, and a pressure loss in the tire of the wheel or damage to the wheel suspension is detected by comparing a momentarily determined pressure loss detection variable (DVEakt) to a learned pressure loss detection variable (DVEsoll), wherein at least two dimensional variables are determined from a wheel speed signal (w) of the wheel, each representing a dimension for the extent of a frequency or a frequency range in the vibratory behavior of the wheel, and that the pressure loss detection variable (DVE) is derived from the two dimensional variables (e1, e2, e3), particularly from a ratio of the two dimensional variables (e2/e3), and a tire pressure monitoring system.
