摘要： In the method and device for tuning a first oscillator with a second oscillator respective response signals of the first oscillator are produced from corresponding frequency-shifted and/or phase-shifted signals of the second oscillator. The first oscillator is tuned to the second oscillator according to the difference of the respective response signals. For amplitude correction a quotient is formed by dividing an output signal by the sum of the response signals. The method and device according to the invention are especially useful in a rotation rate sensor. The invention also includes a rotation rate sensor, which includes a device for determining rotation rate from the oscillations of a first and second oscillator and the device for tuning the first oscillator with the second oscillator.

摘要： A rotation rate sensor is described that operates on the principle of a resonant vibration gyrometer and is excited by an amplitude-regulated oscillator loop. This sensor is used for instance to ascertain the yaw speed of a vehicle. The effect of Coriolis acceleration is evaluated, which is a measure for the current yaw speed. To monitor the operability of the sensor and the associated electronics, an integrated self-test function is used, which as a so-called BITE function introduces a defined interference variable after actuation of a test input. This defined interference variable leads to an estimatable output voltage, whose occurrence is evaluated for error detection.
