Abstract
A receiving assemblage is provided for a control device in a vehicle, having a voltage generator for generating a synchronization pulse, which encompasses a first voltage source, a current source, and a current sink, the voltage generator generating the synchronization pulse within predefined specification limits with a predefined shape and a predefined time-related behavior, and the receiving assemblage outputting the synchronization pulse via a data bus to at least one sensor for synchronization of a subsequent signal transfer, the voltage generator generating the synchronization pulse via the current source and the current sink, substantially as a sinusoidal oscillation, by charging and/or discharging a bus load, and to a method for generating a synchronization pulse.

9. A receiving assemblage for a control device in a vehicle, comprising:
-
a voltage generator for generating a synchronization pulse, the voltage generator including; a first voltage source, a current source, and a current sink, wherein the voltage generator generates a synchronization pulse within predefined specification limits with a predefined shape and a predefined time-related behavior; and a data bus via which the synchronization pulse is outputted to at least one sensor for synchronization of a subsequent signal transfer, wherein the voltage generator generates the synchronization pulse via the current source and the current sink, substantially as a sinusoidal oscillation, by at least one of charging and discharging a bus load, wherein the voltage generator compares a voltage value at an end of the synchronization pulse with a corresponding voltage value of a supply voltage of a second voltage source of a residual receiver circuit, wherein the voltage generator ascertains a voltage difference, the voltage generator applying control to the current source and to the current sink as a function of the ascertained voltage difference in such a way that the ascertained voltage difference drops below a predefined threshold value. - View Dependent Claims (11)

16. A method for generating a synchronization pulse for synchronizing a subsequent signal transfer between a receiving assemblage and at least one sensor via a data bus in a vehicle, comprising:
-
generating the synchronization pulse within predefined specification limits with a predefined shape and a predefined time-related behavior; transferring the synchronization pulse from the receiver assemblage to the at least one sensor at a beginning of the signal transfer between the at least one sensor and the receiver assemblage, the synchronization pulse being generated substantially as a sinusoidal oscillation; comparing a voltage value at an end of the synchronization pulse with a corresponding voltage value of a supply voltage of a second voltage source of the residual receiver circuit; ascertaining a voltage difference; and applying a control to a current source and to a current sink as a function of the ascertained voltage difference in such a way that the ascertained voltage difference drops below a predefined threshold value.
