A yaw rate sensor () includes a movable mass structure () and a drive component () which is suitable for setting the movable mass structure () in motion (), and an analysis component () which is suitable for detecting a response () of the movable mass structure () to a yaw rate (&#x3a9;). A method for functional testing of a yaw rate sensor () includes the following steps: driving a movable mass structure (), feeding a test signal () into a quadrature control loop () at a feed point () of the quadrature control loop (), feeding back a deflection () of the movable mass structure (), detecting a measure of the feedback of the movable mass structure (), and reading out the response signal () from the quadrature control loop (). In the yaw rate sensor () and also in the method, the readout of the response signal () in relation to a processing direction () of the test signal () is provided between a feed point () for a test signal () and an actuator () for feeding back a deflection () of the movable mass structure ().

Self-test for yaw rate sensors

A sensor device includes: a sensor module mounted on a conductor board; a sensitive element which is sensitive to a variable; a self-test control unit implementing a self-test program, the self-test control unit applying a self-test variable to the sensitive element, taking the self-test program into account; a detection unit detecting a characteristic of the sensitive element which is altered as a result of the applied self-test variable and providing an actual self-test response, taking the altered characteristic into account; and a comparator unit provided on or in the sensor module, the comparator unit comparing the actual self-test response to at least one specified setpoint self-test response and providing comparative information.

Sensor device with self-test capability

A method for transmitting data frames between a master device and one or more slave devices via a bus system having at least one request line for transmitting request data frames from the master device to the slave devices, a response line for transmitting response data frames from the slave devices to the master device and at least one selection line for activating the slave devices, the request data frames and the response data frames being transmitted together with at least one address bit for addressing one of the slave devices, the useful data bits and at least one length-indicating bit for indicating the data frame length.

Data transmission method between master and slave devices

An oscillating circuit includes an analog oscillation element. The oscillating circuit includes at least one analog-to-digital conversion device. A method is for operating an oscillating circuit, in which a mechanical oscillator oscillates at a natural frequency. The oscillation amplitude is measured and digitized. A digital control signal is generated from this with the aid of a digital amplitude controller. A driving signal is generated, in turn, from the digital control signal, the driving signal driving the mechanical oscillator with the aid of a drive unit. This control loop stabilizes the oscillation amplitude.
