Abstract:
1. A method for functional testing of a yaw rate sensor, the method comprising: driving a movable mass of the yaw rate sensor in a first direction; feeding a test signal into a quadrature control loop of the yaw rate sensor at a feed point of the quadrature control loop, the quadrature control loop including an actuator to drive the movable mass in a manner to counteract movement of a detection mass of the yaw rate sensor in a second direction orthogonal to the first direction as a result of the driving of the movable mass; detecting a measure of movement of the detection mass in the second direction; feeding back a signal based on the measure of movement of the detection mass by the quadrature control loop to the actuator of the quadrature control loop; and reading out a response signal from the quadrature control loop at a readout location between the feed point and the actuator of the quadrature control loop from a perspective of a processing direction of the quadrature control loop.
