The invention relates to a fuse
system (1) for at least one load (V1, V2, Vn) of a vehicle, having a fuse apparatus (10) that comprises at least one electronic fuse (S1, S2, Sn) for the at least one load (V1, V2, Vn) and an evaluation and
control circuit (12) that evaluates the load current (iL1, iL2, iLn) through the at least one electronic fuse (S1, S2, Sn) and compares said load current with at least one prescribed disconnection criterion of a first parameter set (P1), wherein the evaluation and
control circuit (12) initiates a trip process that trips the at least one electronic fuse (S1, S2, Sn) and disconnects the load current (iL1, iL2, iLn) to the corresponding load (V1, V2, Vn) if the at least one prescribed disconnection criterion is satisfied. In this case, an evaluation and
control unit (20) additionally evaluates the load current (iL1, iL2, iLn) through the at least one electronic fuse (S1, S2, Sn) and compares the load current (iL1, iL2, iLn) with at least one prescribed complex disconnection criterion of a complex parameter set (P1K) and interrupts the trip process initiated by the evaluation and
control circuit (12) by outputting at least one corresponding
control signal to the evaluation and control circuit (12) for a predetermined period of time, wherein the evaluation and control circuit (12) terminates the trip process if the load current (iL1, iL2, iLn) does not satisfy the at least one complex disconnection criterion or trips the at least one electronic fuse (S1, S2, Sn) and disconnects the load current (iL1, iL2, iLn) to the corresponding load (V1, V2, Vn) if the load current (iL1, iL2, iLn) satisfies the at least one complex disconnection criterion, wherein the evaluation and control circuit (12) monitors a functionality of the evaluation and
control unit (20) and, in the event of erroneous operation of the evaluation and
control unit (20) being identified, changes over to an emergency mode in which the evaluation and control circuit (12) ignores control signals from the evaluation and control unit (20) and evaluates the load current (iL1, iL2, iLn) through the at least one electronic fuse (S1, S2, Sn) and compares said load current with at least one prescribed disconnection criterion of an emergency parameter set (PNL), wherein the evaluation and control circuit (12) trips the at least one electronic fuse (S1, S2, Sn) and disconnects the load current (iL1, iL2, iLn) to the corresponding load (V1, V2, Vn) if the at least one prescribed disconnection criterion of the emergency parameter set (PNL) is satisfied.
