Abstract

A device for controlling a device by using a rotation-rate sensor. In order to provide a device for determining a triggering signal for a safety device which allows a particularly compact implementation of the device, the device is set up to ascertain an acceleration variable on the basis of a first sensor signal for a first seismic mass of the rotation-rate sensor and the second sensor signal for a second seismic mass of the rotation-rate sensor and to control the device as a function of the acceleration variable.

Claims

detecting a first sensor signal for a first seismic mass of the rotation-rate sensor;

detecting a second sensor signal for a second seismic mass of the rotation-rate sensor;

ascertaining an acceleration variable on the basis of the first sensor signal and the second sensor signal; and

controlling the device as a function of the acceleration variable.

2. The method according to claim 1, further comprising:

ascertaining a rotation-rate variable on the basis of the first sensor signal and the second sensor signal; and

controlling the device as a function of the rotation-rate variable.
