FIELD: transportation.
SUBSTANCE: invention object is a method for estimating the angular velocity of a railway vehicle moving along a track comprising an inertial unit (14) comprising at least one angular velocity sensor, the method comprising the stage of measuring the instantaneous angular velocity issued by the sensor. The method comprises: the stage of determining the angular velocity deviation measured around at least one axis. The velocity deviation is assumed to be equal to the angular velocity measured around this axis when said measured angular velocity is substantially constant for a predetermined time (T); and the stage of calculating the estimated angular velocity by subtracting a previously determined velocity deviation from the measured angular velocity.
EFFECT: increasing the accuracy of the angular velocity signal without the use of additional sensors.
