Abstract
A supply circuit (100) having a computer device (110) for diagnosing a connecting circuit (120), in particular for power electronics in a vehicle, wherein the supply circuit (100) comprises a first and a second supply source (102, 104) for supplying a first and a second consumer (202, 204). The supply circuit (100) comprises a computer device (110). The computer device (110) is configured to determine an applied second supply voltage (UA2) on the second consumer (204) and to diagnose the correct operation of the connecting circuit (120) on the basis of the determined applied second supply voltage (UA2).
Claims13
A supply circuit (100) having a computer device (110) for diagnosing a connecting circuit (120) for power electronics in a vehicle,
- wherein the supply circuit (100) comprises a first and a second supply source (102, 104) for supplying a first and a second consumer (202, 204),
- wherein the first supply source (102) is configured to provide a first supply voltage (Ul) for the first consumer (202) after the first supply source (102) is switched on and to provide a third supply voltage (U3) for the connecting circuit (120), wherein the third supply voltage can also be provided to the second consumer (204) by means of the connecting circuit (120),
- wherein the second supply source (104) is configured to provide a second supply voltage (U2) for the second consumer (204) after the second supply source (104) is switched on,
- wherein the connecting circuit (120) comprises a switching element and is configured to electrically connect the third supply voltage (U3) to the second consumer (204) by closing the switching element and to disconnect the third supply voltage (U3) from the second consumer (204) by opening the switching element,
- wherein the supply circuit (100) comprises a computer device (110), and
- wherein the computer device (110) is configured to determine an applied second supply voltage (UA2) on the second consumer (204),
- and to diagnose the correct operation of the connecting circuit (120)
- based on the determined applied second supply voltage (UA2).
(canceled)
A non-transitory, computer-readable medium comprising instructions which, when executed by a computer (110) of a supply circuit (100) cause the computer to determine (520) an applied second supply voltage (UA2) on a second consumer (204);
- diagnose (550) the correct operation of a connecting circuit (120) based on the determined applied second supply voltage (UA1, UA2),
- wherein the supply circuit 100 comprises a first and a second supply source (102, 104) for supplying a first and the second consumer (202, 204),
- wherein the first supply source (102) is configured to provide a first supply voltage (Ul) for the first consumer (202) after the first supply source (102) is switched on and to provide a third supply voltage (U3) for the connecting circuit (120), wherein the third supply voltage is also provided to the second consumer (204) via the connecting circuit (120),
- wherein the second supply source (104) is configured to provide a second supply voltage (U2) for the second consumer (204) after the second supply source (104) is switched on, wherein the connecting circuit (120) comprises a switching element and is configured to electrically connect the third supply voltage (U3) to the second consumer (204) by closing the switching element and to disconnect the third supply voltage (U3) from the second consumer (204) by opening the switching element.
