Abstract: A rotation rate sensor including a substrate having a principal plane of extension, and a structure movable with respect to the substrate; the structure being excitable from a neutral position into an oscillation having a movement component substantially parallel to a driving direction, which is substantially parallel to the principal plane of extension. To induce the oscillation, the rotation rate sensor includes a comb electrode moved along with the structure and a comb electrode fixed in position relative to the substrate. The excitation is produced by applying a voltage to the moving comb electrode and/or to the stationary comb electrode. Due to a rotation rate of the rotation rate sensor about an axis running substantially perpendicularly to the driving direction and substantially perpendicularly to the detection direction, a force applied to the structure with a force component along a detection direction substantially perpendicular to the driving direction is detectable.

Abstract: A method/system for calibrating a vehicle sensor, including detecting data about the vehicle's surroundings using the sensor, and ascertaining stationary structures using the detected first data pieces. Stationary structures are selected for later calibration, and potential parking positions are determined. A parking position is selected from the potential parking positions so that after parking, stationary structures selected for a calibration of the sensor are in the sensor's field of vision. The vehicle is parked, and the position of the stationary structures selected for the calibration of the sensor is stored. After the vehicle start, second data pieces about the vehicle's surroundings are detected using the sensor, and instantaneous positions of the selected stationary structures are ascertained using the detected second data pieces. The instantaneous position are compared with the stored positions, and deviations between the instantaneous positions and the stored positions determined.
