Abstract:
Method for protection of a switching device controlled by a control unit, through which an electric drive can be disengaged during the period of an overvoltage surge caused by a load dump in the electrical system of a vehicle, in which the drive current rises to a maximum value in a first slot within the duration of the overvoltage surge and drops in the second slot connected to the first time slot, with the following process steps: recognition of a load dump by recording a limit voltage value in the electrical system by the control unit, disengagement of the electric drive in the event of a load dump at a switching time stipulated by the control unit, which lies after the first time slot.
