DEVICE FOR SUPPLYING POWER TO A CONTROL UNIT AND METHOD FOR MONITORING A POWER SUPPLY

A device for supplying power to a vehicle-control-unit, including: a first-connection (FC) for a first power-supply-path (PSP), a second-connection (SC) for a second PSP and a neutral-point for connecting the first-PSP and the second-PSP; a first-switch having first and second contacts, the first-contact being connected to the FC and the second-contact being connected to the neutral-point, and a second-switch having first and second contacts, the first-contact being connected to the SC and the second-contact being connected to the neutral-point; a first-measuring-contact for capturing a first-measured-value representing a voltage-potential of the first-PSP, and a second-measuring-contact for capturing a second-measured-value representing a voltage-potential of the second-PSP; a control-device to keep one of the switches open and to keep the other of the switches closed in response to a test-state; and a monitoring-device to provide a monitoring-signal using the first and second measured-values if in the test-state.
