A digital communication system user, via which a first logic signal and a second logic signal are transmitted, includes an activation circuit that includes encompassing a supply unit, a switching unit, a transmission unit, and a communication interface. The supply unit provides an internal supply voltage, the switching unit couples the supply unit to the transmission unit to supply the transmission unit with the internal supply voltage, and the transmission unit outputs a wake-up signal, which includes the first logic signal, to the communication interface in response to being supplied with the internal supply voltage by the supply unit, and subsequently continuously outputs the second logic signal to the communication interface until the switching unit separates the transmission unit from the supply unit by.

User for a digital communication system and corresponding communication system

A receiver configuration for a control unit in a vehicle having a voltage generator for generating a synchronization pulse, which includes a first voltage source, a current source and a current sink, the voltage generator generating the synchronization pulse within predefined specification limits having a predefined shape and a predefined time behavior, and the receiver configuration outputting the synchronization pulse for synchronizing a signal transmission via a databus to at least one sensor. A method is also provided for generating a synchronization pulse. The voltage generator generates the synchronization pulse via the current source and the current sink by charging and/or discharging a bus load essentially as a sinusoidal oscillation.

Receiver configuration for a control unit in a vehicle and method for generating a synchronization pulse

A method for ascertaining a load capacitance of a data bus includes reading in and a determining task. In the reading in, a scaling factor of a synchronization pulse of the data bus is read in. In the determining, the load capacitance is determined using the scaling factor and a processing rule.

Method and control unit for ascertaining a capacitance value of a data bus

A sensor system for a vehicle includes: at least one sensor unit; and one evaluation and control unit transmitting a synchronization signal via a communication connection to the sensor unit. The sensor unit transmits a sensor signal representing the measured variable via the communication connection to the evaluation and control unit. The evaluation and control unit ascertains an instantaneous signal quality of the received sensor signal and transmits a piece of information about the ascertained instantaneous signal quality to the sensor unit. The sensor unit predefines a modulation amplitude for the transmission of the sensor signal as a function of the ascertained instantaneous signal quality.

Sensor system for a vehicle and operating method for a sensor system in a vehicle

A method for establishing at least one fault in connecting lines between electronic connection units and peripheral units, which are independent of one another, includes: outputting a start signal from the control unit to a first of the connection units, to start the establishment of the fault; applying a test signal to an interface of a first one of the connection units, the application of the test signal being monitored and/or controlled by a non-volatile first algorithm of the first connection unit; registering a cross-coupling of the test signal to an interface of a second connection unit and storing a fault value representing the cross-coupling in a first register, the registration and the storage of the fault value being monitored and/or controlled by a nonvolatile second algorithm of the second connection unit.

In a control unit for passenger protection and a method for triggering passenger protection devices, a Manchester-coded signal is supplied by an interface and the Manchester-coded signal is decoded by a coding unit, so that an analyzer unit performs the triggering of passenger protection devices as a function of the decoded signal. The decoding unit uses a shift register structure for decoding and oversampling for the Manchester-coded signal.
