In a method for electronic tuning of the frequency of the read oscillation to the frequency of the stimulation oscillation in a Coriolis gyro (11) according to the invention, the resonator (2) of the Coriolis gyro (1') has a disturbance force applied to it such that the stimulation oscillation remains essentially uninfluenced, with the read oscillation being changed such that a read signal which represents the read oscillation contains a corresponding disturbance component. The disturbance force is in this case defined as that force which is caused by the signal noise in the read signal. The frequency of the read oscillation is controlled such that the strength of the disturbance component which is contained in the read signal is a minimum.
L'invention concerne un procédé de syntonisation électronique de la fréquence d'oscillation de sortie sur la fréquence d'oscillation d'excitation d'un gyroscope vibrant (1'). Selon l'invention, le résonateur (2) de ce gyroscope vibrant (1') est soumis à l'action d'une force perturbatrice, de façon que l'oscillation d'excitation reste sensiblement inchangée, l'oscillation de sortie étant modifiée de manière qu'un signal de sortie représentant cette oscillation de sortie comporte une composante perturbatrice correspondante. Ladite force perturbatrice est définie comme étant la force générée par le bruit du signal de sortie. La fréquence d'oscillation de sortie est régulée de façon que l'intensité de la composante perturbatrice contenue dans le signal de sortie soit minimale.
