CIRCUIT MODULE FOR ISOLATING COMPONENTS OF A MULTI-VOLTAGE VEHICLE ELECTRICAL SYSTEM

摘要

A multi-voltage electrical system for a vehicle, which comprises a first subsystem with a transceiver and a second subsystem with a control unit, is provided. A first control signal path which couples a first signal output of the transceiver to a first signal input of the control unit is formed and arranged to transmit a first control signal from the first signal output to the first signal input. The first control signal path comprises a first circuit module which is formed to assume a blocking condition in response to a faulty operating voltage supply in the first subsystem and/or in the second subsystem, in which the transmission of the first control signal from the first signal output to the first signal input via the first control signal path is inhibited.
