Method and arrangement for detecting a pressure loss of tires in motor vehicle
First Claim
1. Method for detecting a pressure loss in tires in a motor vehicle during travel, especially for detecting the dropping of the pressure below a definable threshold value (critical tire pressure), by evaluating sensor determined angular velocities of the wheels of the motor vehicle or evaluating informations, which indicate the angular velocities on the basis of time intervals, characterized in that the pressure loss detection method includes two or more submethods (Prog A, Prog B, Prog S, Prog V) which are each by themselves a separately operable method for measuring the pressure in a motor vehicle tire or for detecting a critical tire pressure, the steps of the submethods being carried out in parallel or quasi parallel.

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.
