Abstract: A controller system in which a plurality different main functions are integrated includes a plurality of microcontrollers. Each of the microcontrollers is associated with one of the main functions. At least one monitoring unit is implemented for the plurality of the main functions, for example a brake monitor and a comfort monitor. When the at least one monitoring unit detects a defect of a main function in the controller, only the defective main function is deactivated.

Abstract: Disclosed is a device for activating a security system in a vehicle including a first and second vehicle sensor (4). The sensor include, respectively, a measuring value sensor (4.1) which can detect acceleration and structure-borne noise, and a central unit (2) which evaluates the signals of at least two vehicle sensors (4) and activates the security system according to the signals.

Abstract: Occupant protection systems in a motor vehicle are activated in the event of a crash that puts the occupants of the vehicle at risk. A processor-based trigger system evaluates signals of crash sensors and actuates the occupant protection systems. Signatures that are produced by impacts on the vehicle body by means of a crash sensor system are detected and preprocessed directly on site of the crash sensor mounting areas. The crash sensor system includes a plurality of similar multifunctional peripheral crash sensors located in various areas of the vehicle body. The preprocessed signatures or variables derived therefrom are evaluated by means of a crash algorithm associated with the trigger system, in terms of kind, intensity, direction and time of the crash signatures and/or occupant risk signatures.

Abstract: A method for the transmission of sensor data from a sensor assembly to one or more receivers is presented, in which, in response to a control signal, additional data are transmitted at least temporarily for a short time instead of the sensor data, whereby only a certain limited value range of the value range that is available for the sensor data transmission is used for the transmission of the additional data, so that even with receivers which do not recognize that the transmitted data are additional data, erroneous functions or malfunctions are to be excluded. Thus, especially that value range of the sensor data signal that is to be attributed to a noise of the quantity to be measured or of the sensor assembly and is therefore not evaluated by the receiver in the normal signal operation, is used for the transmission of the additional data.
