Abstract
The present invention relates to a method for calibrating a gyrometer equipping a vehicle. The method includes a step (a) of acquisition, by the gyrometer, of a measured angular velocity of the vehicle, and, by measuring measured values of at least one quantity representative of the angular velocity of the vehicle. It also includes a step (b) of determination, by a data processor, of values of at least one gyrometer calibration parameter minimising a difference between a first estimated angular velocity of the vehicle and a second estimated angular velocity of the vehicle, wherein the first estimated angular velocity is a function of the measured angular velocity and parameters for calibrating the gyrometer, and the second estimated angular velocity is a function of the measured values of said at least one quantity representative of the angular velocity of the vehicle.
