DEVICE AND METHOD FOR ESTIMATING THE INFLATION STATE OF A TYRE

摘要

The invention relates to a device for estimating the inflation state of a tyre of at least one wheel of an automobile, that comprises a memory (1) for storing a reference signature including a periodic signal corresponding to an inflation and to reference running conditions; a means (2) for determining a current signature including a periodic signal corresponding to an inflation and to current running conditions; a means (3) for comparing the current signature and the reference signature, and capable of outputting a signal based on the deviation between the current signature and the reference signature.
