Abstract

An electronic arrangement in a motor vehicle, in which at least one sensor is connected to a first electronic control unit by a current interface for transmitting signals and/or for supplying power. A connection of the current interface to at least one supply potential is provided via a second electronic control unit.

First claim

The invention claimed is:

1. An electronic arrangement in a motor vehicle, comprising:
at least one sensor connected to a first electronic control unit by a current interface for transmitting signals and/or for supplying power;
wherein a connection of the current interface to at least one supply potential is provided via a second electronic control unit;
wherein the first electronic control unit comprises a monitoring mechanism for detecting a fault in the connection to the supply potential, which connection is implemented via the second electronic control unit;
wherein the first electronic control unit comprises at least one switching element and/or at least one functional module for the connection to the supply potential, the connection of which supply potential is implemented via the second electronic control unit;
wherein in response to the fault being detected in the connection to the supply potential, which connection is implemented via the second electronic control unit, a connection to this supply potential is made by the first electronic control unit.

2. The electronic arrangement as claimed in claim 1 , wherein the first electronic control unit and the second electronic control unit each comprise at least one measuring mechanism for acquiring signals from the sensor.

3. The electronic arrangement as claimed in claim 1 , wherein the second electronic control unit provides a connection to a reference potential of the motor vehicle.

4. The electronic arrangement as claimed in claim 1 , wherein the sensor is an active sensor.
