Abstract
A method is described for controlling a voltage limit for a maximally permissible operating voltage in an on-board electrical system of a vehicle, including the step of adapting the voltage limit in dependence on vehicle data, wherein an actual voltage is ascertained and the actual voltage is short-circuited or limited if the actual voltage exceeds the voltage limit. Also described is a device for controlling a voltage limit for a maximally permissible operating voltage in an on-board electrical system of a vehicle, having an adaptation device for adapting the voltage limit in dependence on vehicle data.

A method for controlling a voltage limit for a maximally permissible operating voltage in an on-board electrical system of a vehicle, comprising:
- regulating an actual voltage of the on-board electrical system to a desired voltage, wherein the desired voltage is less than the maximally permissible operating voltage;
- one of limiting and short-circuiting the actual voltage if the actual voltage exceeds the maximally permissible operating voltage in the on-board electrical system;
- and
- adapting the voltage limit in dependence on vehicle data.
