Abstract: In a method for recognizing a loss of pressure in a tire of a motor vehicle, an anomaly in the chassis, such as a loss of tire pressure, is recognized by comparing an indicative value indicative of the chassis anomaly or the tire pressure with a comparative value. An instantaneous indicative value that is indicative of the chassis anomaly or the tire pressure is determined. A comparative value is stored in a learning step when a learning threshold is reached, and previously determined indicative values are used for determining the comparative value to be stored. An anomaly in the chassis or a loss of pressure in a tire is recognized by comparing the instantaneous indicative value with the comparative value. An intermediate value or determined indicative value is stored if the predefinable learning threshold has not been reached.

Abstract: 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.

Abstract: 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.
