Abstract: The invention discloses a method for compensating temperature in a system for tire pressure monitoring which is especially implemented by detecting a tire pressure and/or by detecting a tire pressure loss. The method is especially characterized in that the temperature is compensated by determining the gas temperature in the tire by way of at least two items of temperature information and by taking the determined temperature as a basis for said tire inflation monitoring. One significant advantage of this method involves that externally active temperature changes, such as a heat-emitting brake disc causing the wheel rim of the tire and, hence, also a temperature sensor arranged thereat to be heated more intensely than the gas in the tire, do not lead to an indication error with respect to the tire pressure (or a spurious alarm).

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 invention relates to a method for detecting the pressure loss in the tires of a motor vehicle by evaluating the wheel speeds. The pressure evaluating method comprises two or more partial methods Prog A, Prog B, Prog S, Prog V, which each per se represents an independent functional method for measuring the pressure of a motor vehicle tire. The steps of these partial methods are carried out in parallel or quasi parallel. The invention further relates to a device for controlling the braking force and/or dynamics of vehicle movement and for measuring the pressure of vehicle tires. A microprocessor that is linked with the wheel speed sensors and optionally with additional sensors for the dynamics of vehicle movement processes the partial methods described above as well as a method known per se for controlling the braking force and/or dynamics of vehicle movement.
