Supplying current/voltage to at least one electrical load in motor vehicle involves at least partially electronically controlled changeover to redundant electrical supply line if fault detected

摘要

The method involves using a current/voltage supply stage (44) connected to the load (34) via electrical supply lines. At least one first type of line (36,36') is connected to a reference potential and at least another type (35,35') to a different potential. There are at least two lines of each type and they are monitored for faults to enable changeover, under at least partial electronic control, to a line of the same type if a fault is detected. Independent claims are also included for the following: a circuit containing a current/voltage supply stage and a use of the circuit in an electrical braking system for motor vehicles.
