A vehicle electrical system for a vehicle, wherein the vehicle electrical system (38, 38'), in addition to at least one first, voltage-sensitive electric consumer (42, 42'), furthermore has at least a second, non-voltage-sensitive electric consumer (44, 44') and a first voltage supply unit (40, 40'), which provides a supply voltage (U2, U2'), wherein furthermore provided are: a storage unit (34, 34'), which is configured to store electric energy at least temporarily, a second voltage supply unit (36, 76) to provide a charge voltage (U1, U1'), a switching unit (46, 46'), to which at least the first voltage-sensitive electric consumer (42, 42'), the storage unit (34, 34'), the first voltage supply unit (40, 40') and the second voltage supply unit (36, 76) are connected, and a control unit (30, 30'), characterised in that the control unit (30, 30) is configured, for the stabilisation of a voltage applied to the first, voltage-sensitive electric consumer (42, 42'), to determine whether a stabilisation of the voltage applied to the first, voltage-sensitive electric consumer (42, 42') is to be carried out, wherein the control unit (30, 30') is furthermore configured, as long as a stabilisation is not to be carried out, to activate the switching unit (46, 46') in such a way that the first, voltage-sensitive electric consumer (42, 42') is connected to the first voltage supply unit (40, 40'), and, as soon as a stabilisation is to be carried out, to activate the switching unit (46, 46') in such a way that the first, voltage-sensitive electric consumer (42, 42') is connected to a series connection formed from the storage unit (34, 34') and the first voltage supply unit (40, 40') in order to thereby supply the first, voltage-sensitive electric consumer by a voltage supplied by the series connection to compensate an existing reduction in the supply voltage (U2, U2'), wherein the control unit (30, 30') is furthermore configured, following a stabilisation that has taken place, to activate the second voltage supply unit (36, 76), the second, non-voltage-sensitive electric consumer (44, 44') and the switching unit (46, 46'), in each case at least temporarily, in such a way that the second voltage supply unit (36, 76) provides a charge voltage (U1, U1'), the value of which is greater than the supply voltage (U2, U2') provided by the first voltage supply unit (40, 40'), in that an electric current flows, at least temporarily, through the second, non-voltage-sensitive electric consumer (44, 44'), and in that it is possible to charge the storage unit (34, 34') via a current path (62, 62') configured by the second voltage supply unit (36, 76) and the second, non-voltage-sensitive electric consumer (44, 44'). a storage unit (34, 34'), which is configured to store electric energy at least temporarily, a second voltage supply unit (36, 76) to provide a charge voltage (U1, U1'), a switching unit (46, 46'), to which at least the first voltage-sensitive electric consumer (42, 42'), the storage unit (34, 34'), the first voltage supply unit (40, 40') and the second voltage supply unit (36, 76) are connected, and a control unit (30, 30'), characterised in that the control unit (30, 30) is configured, for the stabilisation of a voltage applied to the first, voltage-sensitive electric consumer (42, 42'), to determine whether a stabilisation of the
