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 (DVEsoil), 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.

Abstract: A system and method for indirect tire pressure monitoring. A pressure loss variable (X, f, c) is determined based on an analysis of an oscillation behavior of a tire of a motor vehicle for the detection of a pressure loss in the tire of a wheel. A variable (?, ?/v) representing an increase (?) of a wheel torque slip curve, or depending on an increase (?) of a wheel torque slip curve (?/v), is determined from the oscillation behavior of the tire, and the variable (?, ?/v) and the pressure loss variable (X, f, c) are used for detecting the pressure loss.

Abstract: A method for the detection of the loading of a motor vehicle determines a loading condition of the vehicle using an analysis of the rotational behavior of the wheels. In a frequency analysis, it determines the natural frequencies of the wheels and looks at the amplitudes of the tire noise around those frequencies, which amplitudes change when the loading condition changes.
