ON-BOARD SYSTEM FOR A VEHICLE AND DEVICE FOR CONTROLLING A CURRENT FLOW IN AN ON-BOARD SYSTEM OF A VEHICLE

摘要

The invention relates to an on-board system for a vehicle and to a device (V) for controlling a current flow in an on-board system of a vehicle. The invention further relates to a vehicle, in particular a motor vehicle, comprising said on-board system or said device. The on-board system according to the invention, or the device according to the invention, has a control device (SE1) and an emergency power source (NQ) for closing a self-locking switch (S1) controlling the current flow in the on-board system in order to prevent a possible parasitic current injection (Ii) when a faulty voltage drop occurs, and to thus prevent system overheating.
