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 (α, α/v) representing an increase (α) of a wheel torque slip curve, or depending on an increase (α) of a wheel torque slip curve (α/v), is determined from the oscillation behavior of the tire, and the variable (α, α/v) and the pressure loss variable (X, f, c) are used for detecting the pressure loss.

17. A method for indirect tire pressure monitoring, in which a pressure loss identification variable (X, f, c) is determined for identification of a pressure loss at the tire of the wheel on the basis of an analysis of the oscillation behavior of a wheel of a motor vehicle, wherein a characteristic variable (α

/v), which represents a gradient (α
) of a wheel torque slip curve, or depends on a gradient (α
) of a wheel torque slip curve (α
/v), is determined from the oscillation behavior of the wheel, and wherein the characteristic variable (α
, α
/v) and the pressure loss identification variable (X, f, c) are used for pressure loss identification. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
