PCT No. PCT/DE95/01796 Sec. 371 Date Jun. 27, 1997 Sec. 102(e) Date Jun. 27, 1997 PCT Filed Dec. 15, 1995 PCT Pub. No. WO96/21138 PCT Pub. Date Jul. 11, 1996A 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. |
