Abstract
L’invention concerne un procédé de mesure de l’entrefer (E) entre un capteur (1) de rotation et une roue phonique (2), le capteur de rotation étant à reluctance variable et comprenant une première voie (A) de mesure et une deuxième voie (B) de mesure correspondant à au moins deux bobinages indépendants du capteur, le procédé étant mis en œuvre au moyen d’une unité de commande (3) connectée au capteur (1) de rotation et comprenant les étapes suivantes : - injection d’une tension alternative (VA) d’amplitude fixe sur la première voie du capteur ; - mesure d’une tension induite (VB) sur la deuxième voie de mesure (B) ; - estimation d’un entrefer (E) à partir de la tension injectée sur la première voie et de la tension mesurée sur la deuxième voie. Figure pour l’abrégé : Figure 1The invention relates to a method for measuring the air gap (E) between a rotation sensor (1) and a tone wheel (2), the rotation sensor having variable reluctance and comprising a first measurement channel (A) and a second measurement channel (B) corresponding to at least two independent windings of the sensor, the method being implemented by means of a control unit (3) connected to the rotation sensor (1) and comprising the following steps: - injection of an alternating voltage (VA) of fixed amplitude on the first channel of the sensor; - measurement of an induced voltage (VB) on the second measurement channel (B); - estimation of an air gap (E) from the voltage injected on the first channel and the voltage measured on the second channel.
