Disclosed is a method for detection of a pressure loss in motor vehicle tires, which detects pressure loss on at least one vehicle tire based on several parameters, which are calculated from the rolling circumference of the tires. To this end, currently calculated parameters are compared with learnt values of the parameters.

Method for recognition of a pressure loss in motor vehicle tires

Disclosed is a method of indirect tire pressure monitoring. The method includes: learning test variables (DIAG, SIDE, AXLE), which describe the rotational movements of the wheels; determining rolling circumference differences (&#x394;DIAG, &#x394;SIDE, &#x394;AXLE) from actually determined test variables and the learnt test variables; learning at least one torsion natural frequency ffor at least one tire from the oscillation behavior of the individual tires; determining at least one shift of the torsion natural frequency &#x394;ffrom at least one actually determined torsion natural frequency and from the at least one learnt torsion natural frequency; and combining the rolling circumference differences (&#x394;DIAG, &#x394;SIDE, &#x394;AXLE) with the at least one shift of the torsion natural frequency fin a joint warning strategy for detecting and warning of tire inflation pressure loss.
