The present device relates to a method of improving a indirect measurement tire pressure detection system. Such systems include a system that detects pressure loss based on wheel speed data. The present method determines reference values dependent upon driving parameters and produces a two-dimensional or multi-dimensional closed range of driving parameters. The closed range of driving parameters uses reference values that are determined to be currently valid.

Method for improving a system for recognizing tire pressure which is measured in an indirect manner

The present invention relates to a method of detecting growth of the dynamic tire circumference (circumferential growth or tire growth), wherein at least one reference value Ref is produced on the basis of wheel speed information, said reference value representing in particular a sidewise and/or crosswise relation of the motor vehicle wheels, and wherein the time variation of the reference value(s) is examined and, further, tire growth is detected on the basis of said variation.
