Abstract

The present invention relates to a method of detecting pressure loss in vehicle tires, wherein a reference value is produced from signals, especially time measurement values, representative of the wheel rotational speeds of a plurality of vehicle wheels, and pressure loss is concluded from a comparison of a currently determined reference value with at least one comparative value in case the currently determined reference value exceeds or falls below the comparative value, and pressure loss in vehicle tires is detected by using at least one reference value which is produced by dividing the sums of respectively two signals representative of the wheel rotational speeds.
