Abstract

The invention relates to a method for dynamic voltage adjustment in an electrical system (110) of a vehicle (100), in particular for a driver assistance system (140) and / or autonomous driving functions, wherein the method comprises the following steps: • Continuous monitoring (10) of an electrical resistance in at least one path (111) of the electrical system (110), in particular in a safety-critical path (111) of the electrical system, by means of a diagnostic module (120), • Detection (20) of an increase in resistance in the path (111) of the electrical system (110) by means of an electronic fuse (121) of the diagnostic module (120), • Activation (30) of a voltage control module (130) by means of the diagnostic module (120), • Increase (40) a voltage by means of the voltage control module (130), starting from an output voltage to an overvoltage, and • Controlling (50) the overvoltage back to the output voltage.
