Digital signal transmission system for use in vehicles limits useful on-board system voltage to produce pulse for transmission in or below supply range working interval with lowest rated voltage

摘要

The method involves transmitting digital signals as voltage pulse signals and detecting the information in signals where pulses are in a defined pulse amplitude range. The useful voltage applied by the on-board electrical system used to produce a voltage pulse for transmission over the single-wire interface in the pulse amplitude range is limited to a maximum value in or below the working interval of the supply range with the lowest rated voltage. AN Independent claim is also included for the following: a system for digital signal transmission in motor vehicles.
