| 摘要 |
The invention relates to an on-board supply system (BN) for a vehicle (FZ), comprising a first and a second energy accumulator (ES1, ES2) and a control device (ST) for controlling current flow in the on-board supply system (BN). The invention also relates to a vehicle (FZ), especially a motor vehicle, comprising said on-board supply system and/or said control device (ST). The on-board supply system (BN) or the control device (ST) comprises a first self-locking switch (S1) that controls the current flow in the on-board supply network (BN). In order to prevent a potential parasitic current injection (Ii) and system overheating in the on-board supply system (BN), and uncontrolled overcharging of an energy accumulator (Es2), in the event of a defective drop of a first operating voltage (Ves1) provided by the first energy accumulator (ES1), in the on-board supply system, the first switch (S1) is maintained in a closed state in a controlled manner by a second operating voltage (Ves2, Vnq), which is redundantly provided by the second energy accumulator (ES2) and/or an emergency current source (NQ). |
