The invention relates to a method for determining a rate of rotation, in which, as a function of a primary actuating signal (E_PRIM), a sensor element (2), the natural frequency (FE) of which is linearly dependent on its temperature (T), is excited so as to perform a primary oscillation along a first axis (AXIS_1). A primary measurement signal (A_PRIM), which is representative of the primary oscillation, is determined. Also, a secondary measurement signal (A_SEC) is determined which is representative of a secondary oscillation of the sensor element (2) along a second axis (AXIS_2), which together with the first axis (AXIS_1) encloses an angle that is unequal to zero. The natural frequency (FE) of the sensor element (2) is determined. On the basis of the determined natural frequency (FE) only, at least one value is adjusted which affects the primary actuating signal (E_PRIM) and/or at least one other actuating signal. The rate of rotation (N) is determined as a function of an amplitude and/or a phase of the secondary output signal (A_SEC). In addition, a rate of rotation corrective value (E6, E7), which affects the determination of the rate of rotation (N), can be adjusted as a function of the temperature (T).
