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 (ΔDIAG, ΔSIDE, ΔAXLE) from actually determined test variables and the learnt test variables; learning at least one torsion natural frequency fp for at least one tire from the oscillation behavior of the individual tires; determining at least one shift of the torsion natural frequency Δfp from at least one actually determined torsion natural frequency and from the at least one learnt torsion natural frequency; and combining the rolling circumference differences (ΔDIAG, ΔSIDE, ΔAXLE) with the at least one shift of the torsion natural frequency fp in a joint warning strategy for detecting and warning of tire inflation pressure loss.

摘要:
Method for automatically initializing an indirectly measuring tire pressure monitoring system which due a change of the rotational behavior of the vehicle wheels, in particular a change in the rolling circumference detects a deflation on the vehicle wheels by comparing learnt reference values with continuously detected new values (1), where furthermore a deflation on the vehicles wheels is detected by evaluating the natural frequency of the single vehicle wheels (3) and where an automatic initialization (5) is being executed, if the indirectly measuring tire pressure monitoring system during the movement of the vehicle after a standstill detects a deflation on a vehicle wheel compared with the situation before the standstill of the vehicle (2), whereas the evaluation of the natural frequency of the vehicle wheels does not detect a deflation on the same vehicle wheel (4).

摘要:
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.
