Abstract: A reception system for a control unit in a vehicle having a voltage generator for generating a synchronization pulse which generates the synchronization pulse within predefined specification limits and having a predefined shape and a predefined time behavior, the reception system outputting the synchronization pulse for synchronizing a signal transmission via a data bus to at least one sensor, and a method for generating such a synchronization pulse. The voltage generator includes a voltage amplifier which generates the synchronization pulse generally as a sinusoidal oscillation based on a reference voltage.

Abstract: A method of data transmission from a sensor to a control unit and a sensor and control unit are described, the sensor transmitting both differential values and absolute values. The differential values are analyzed in the control unit to perform the function provided, and the absolute values are analyzed for the plausibility check of the function.

Abstract: A device for impact sensing is described which detects an impact by a pressure, a normalized signal being supplied to a processor for analyzing the pressure signal. This normalization may occur either in the pressure sensor, by the sensor element itself or by a signal preprocessor, or in the processor.

Abstract: In a method of monitoring a voltage supply of a control unit in a motor vehicle, a supply module which provides the voltages is connected to the components of the control unit via a RESET line and the RESET line is tested every time the control unit is started or all monitoring limits of the supply module show no fault again after the faults of the monitored voltages have been filtered. This test occurs by forced periodic pulses which are generated on the basis of a shift in the limits of the monitoring bands of the supply voltages. The reference voltages VREGUL and VREF are kept independent of each other here in order to prevent system perturbations.

Abstract: A method for transmitting data from at least one sensor to a control unit via an appropriate two-wire line is described. The method is used to identify any sensor at the control unit and to implement a plurality of logical channels via the appropriate two-wire line. The at least one sensor receives the necessary electrical energy from the control unit via the two-wire line and then transmits the sensor-specific data.
