A vehicle electrical system includes a first system branch with a first nominal voltage U1, a second system branch with a second nominal voltage U2, at least one DC/DC converter configured to transmit energy between the first and second system branches, a first actuating unit to actuate the DC/DC converter(s), a first detection unit to detect an instantaneous voltage Uact,1 of the first system branch, and a comparison unit to compare the detected instantaneous voltage Uact,1 to a first upper voltage threshold value Uo,1 and to a first lower voltage threshold value Uu,1, wherein Uu,1<U1<Uo,1. The first actuating unit actuates the DC/DC converter(s) such that energy is transmitted from the first system branch to the second system branch if Uact,1>Uo,1, and such that energy is transmitted from the second system branch to the first system branch if Uact,1<Uu,1. |
