A method for evaluating measurement data that are obtained by a plurality of sensors. The method includes: the measurement data originating from sensors of a first group are processed by a function evaluation module to form a function signal that, when it is supplied to a driving dynamics system of a vehicle, causes the driving dynamics system to carry out a driving task; the measurement data originating from a second group of sensors are processed by at least a first safety evaluation module to form a first safety signal that, when it is supplied to the driving dynamics system, causes the driving dynamics system to prevent a specified undesired event of the vehicle, the second group containing a proper subset of the first group; the function signal is aggregated with the first safety signal to form a control signal that is capable of being outputted to the driving dynamics system.

A prechamber spark plug, including center and ground electrodes, a housing having an external thread, a cap arranged on the housing and together with the housing defines a prechamber, and an insulator which electrically insulates the center electrode from the housing. The external thread has a thread length in the axial direction. The housing is fastened to the insulator at first and second fixing regions so that a first clamping force at the first fixing region acts from the housing on the insulator, and a second clamping force at the second fixing region acts from the housing on the insulator. The first and second clamping forces are directed in opposite directions to one another in the axial direction. A distance between the first and second fixing regions in the axial direction defines a clamping length. A ratio between the thread length and the clamping length is between 0.7 to 1.3.

A prechamber spark plug. The prechamber spark plug includes: a housing, and a cap which has at least one pass-through opening, the cap being situated at a combustion chamber-side end of the housing. The cap and the housing form a prechamber. An outer cap surface area of the cap, which faces away from the prechamber, has at least one predefined ratio to respectively one further geometric feature of the cap.

A method for operating a data processing unit of a driver assistance system, the unit including main and slave computers. The main computer ascertains surroundings data from a surroundings detection system by using a processing specification. The slave computer operates a communication interface of the data processing unit, using a communication instruction. The method includes initializing, a first testing, a carrying out, a second testing and a forwarding. In initializing, the main computer, in response to a signal, is initialized by performing an initialization instruction on the main computer. In the first testing, the slave computer, in response to the signal, is initialized by performing a self-test instruction on the slave computer. In the carrying out, the communication instruction is performed on the slave computer to send and/or receive data via the communication interface, when the slave computer is tested and while the main computer is initialized. In the second testing, the main computer is tested by performing a test instruction on the slave computer, when the main computer is initialized. In the forwarding, the surroundings data are forwarded via the communication interface by performing the communication instruction on the slave computer, when the main computer is tested.
