Abstract

The invention relates to a method for detecting a drop in pressure of a motor vehicle tire by evaluating wheel speeds determined by sensors. The method for detecting the drop in pressure is based on the detection of a large drop in pressure or a complete drop in pressure using a reduction of the angular velocity or an increase (8) in the dynamic read radius rd of one or more wheels. The invention also relates to a device for controlling the braking power and/or driving dynamics and for measuring the pressure of vehicle tires wherein a microcomputer, which is connected to wheel rotational speed sensors and optionally to driving dynamic sensors, is used to perform the aforementioned method and a known method for regulating the braking power and/or driving dynamics.
