Two-wire bus system for motor vehicle, determines quiescent current or voltage and separates from current or voltage containing measured data

摘要

An evaluation unit (D) includes a quiescent current or voltage determination device (D,C,M) for determining the quiescent current or voltage on the bus lines (BL1,BL2), and an equalizing device for separating the quiescent current or voltage from a current or voltage containing measured data (d). An independent claim is included for a method of operating a bus system.
