    • The invention relates to a first method for calibrating a current sensor (4) which is configured to determine, in an on-board power system (2) of a vehicle, an electric operating current (12) which flows through a measuring resistor (20), on the basis of comparison (38) of a voltage drop at the measuring resistor (20) caused by the operating current (12) and on the basis of a rule (21) which is dependent on the measuring resistor (20), comprising: determining an operating voltage drop (22) brought about at the measuring resistor (20) by the operating current (12); impressing a known electric calibration current (40) into the measuring resistor (20), - detecting an overall voltage drop (4) brought about at the measuring resistor (20) by the calibration current (40) and the operating current (12), filtering the operating voltage drop (22) from the overall voltage drop (42), with the result that a calibration voltage drop (44) which is brought about by the calibration current (40) remains, and calibrating (58) the rule (21), dependent on the measuring resistor (20), on the basis of comparison (57) of the calibration current (40) and of the calibration voltage drop (42).
