Title (EN) METHOD FOR DETERMINING THE INSTANTANEOUS FREQUENCY AND PHASE OF A PERIODIC SIGNAL
(FR) PROCÉDÉ DE DÉTERMINATION DE LA FRÉQUENCE ET DE LA PHASE INSTANTANÉES D'UN SIGNAL PÉRIODIQUE
Abstract:
(EN) Method for locating a pressure sensor in a system for monitoring the tyre pressures of the wheels (1, 2, 3, 4) of a vehicle (V) comprising the following steps: – acquiring a periodic signal characteristic of the frequency to be determined and of which one particular point is characteristic of a reference of the phase of said signal; – identifying a reference sequence in at least one consecutive portion of said signal; – determining how the frequency of the signal evolves with respect to time by calculating a function of the delay between identification of the reference sequence in at least one consecutive portion of the signal; – determining an instant corresponding to a point characteristic of a reference of the phase of the signal during the period of said signal, and from that deducing the way the frequency evolves with respect to time and the instantaneous phase of the signal with respect to the phase reference characteristic point.
(FR) Procédé de localisation d'un capteur de pression dans un système de surveillance de la pression des pneus des roues (1, 2, 3, 4) d'un véhicule (V) comprenant les étapes suivantes: - acquérir un signal périodique caractéristique de la fréquence à déterminer et dont un point particulier est caractéristique d'une référence de la phase dudit signal; - identifier une séquence de référence dans au moins une portion consécutive dudit signal; - déterminer une évolution temporelle de la fréquence du signal par le calcul d'une fonction du délai entre l'identification de la séquence de référence dans au moins une portion consécutive du signal; - déterminer un instant correspondant à un point caractéristique d'une référence de la phase du signal au cours de la période dudit signal, et en déduire l'évolution temporelle de la fréquence, la phase instantanée du signal par rapport au point caractéristique de référence de la phase.
