A method monitors a sensor clock signal in a sensor unit, which is generated and output for a data transfer between the sensor unit and a control unit with a predefined period duration. A reference clock signal having a predefined reference period duration is received. The sensor clock signal is compared to the reference clock signal. Based on the comparison, a deviation of the current period duration of the sensor clock signal from a target period duration is detected. Based on the detected deviation, a counting pulse or a reset pulse is emitted.

Device and method for monitoring a sensor clock signal

A method is described for switching off a communication between at least two bus subscribers, which are connected to one another via a data bus and which transmit during the communication respectively one transmission clock signal in addition to a data signal, at least one of the bus subscribers generating its transmission clock signal and its data signal based on a reference clock signal, as well as a corresponding communication system. In the case of a fault, the reference clock signal is switched off so that the at least one affected bus subscriber no longer transmits a transmission clock signal and no longer transmits a data signal, and the faulty communication is switched off.

A method for transmitting a data packet from a sensor to a controller via a peripheral sensor interface includes transmitting the data packet from the sensor via the sensor interface in a time window of a transmission period of a sensor interface operating mode which is synchronized by the controller. The data packet is re-transmitted by the sensor within the transmission period in at least one additional time window of the transmission period.

A method corrects at least one transmission parameter for data transmission between a sensor unit and a control unit. A sensor timing signal is generated by a sensor oscillator with a predetermined period. The at least one transmission parameter is determined on the basis of the sensor timing signal. A reference timing signal is generated by a reference oscillator with a predefined reference period. The sensor timing signal is compared with the reference timing signal. A deviation of a current period of the sensor timing signal from a reference period is determined on the basis of the comparison. The at least one transmission parameter is corrected on the basis of the determined deviation.

A method for transmitting measured values from a sensor, wherein the measured values are transmitted cyclically, wherein at least two communication slots are provided in one communication cycle, wherein a first measured value, which represents a first physical effect detected by the sensor, is transmitted in a first communication slot, and a second measured value, which represents a second physical effect detected by the sensor, is transmitted in a second communication slot, characterized in that the measured value is transmitted in a communication cycle according to a defined relevance of the currently detected physical effect and/or of the measured value.

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.

A method for commissioning a sensor series circuit configured in a daisy chain topology. A second sensor being downstream from a first sensor. The method includes furnishing a first switch signal to the first sensor to close the first switch, the first switch signal being furnished in response to a successful initialization of the first sensor, monitoring a function of the second sensor during initialization of the second sensor to ascertain whether the second sensor exhibits a fault upon initialization or is initialized correctly, and to furnish a fault signal if it is ascertained that the second sensor exhibits a fault upon initialization; and outputting a suppression signal to the first sensor if the fault signal has been furnished, to prevent the first switch from being closed.
