Patent ID: 7694562

Claim:
A method for the start-up of a rate-of-turn sensor (DRS) that includes at least one oscillator element that is excitable to perform a mechanical oscillating motion; for an operational control of the rate-of-turn sensor, a signal (v(t), x(t)) proportional to an instantaneous speed or a deflection of the oscillator element is amplified, and the amplified signal is used as an operating signal (F(t)) to operate the oscillator element, wherein during a start-up process for the rate-of-turn sensor (DRS), an amplitude (AF) of the operating signal (F(t)) is set to a constant specifiable value (A Fc ); a stimulation frequency of the operating signal (F(t)) is increased essentially continuously from a start value (f 1 ) below the main driving frequency of the oscillating motion to a final value (f 2 ) above a main driving frequency and below a spurious driving frequency while, simultaneously, the deflection (x(t)) and/or the speed (v(t)) of the oscillator element are monitored in order to determine the main driving frequency of the oscillating motion; once the final value (f 2 ) is reached and the main driving frequency is determined, the stimulation frequency of the operating signal (F(t)) is set to the main driving frequency, and an operational regulation of the amplitude (A F ) and the stimulation frequency of the operating signal (F(t)) are released.
