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.
