Abstract
A method for calibrating a current sensor which is configured to determine, in a vehicle's onboard power system, an electric operating current which flows through a measuring resistor, based on comparison of a voltage drop at the measuring resistor caused by the operating current and based on a rule which is dependent on the measuring resistor, including: determining an operating voltage drop brought about at the measuring resistor by the operating current; impressing a known electric calibration current into the measuring resistor, detecting an overall voltage drop brought about at the measuring resistor by the calibration current and the operating current, filtering the operating voltage drop from the overall voltage drop, such that a calibration voltage drop which is brought about by the calibration current remains, and calibrating the rule, dependent on the measuring resistor, based on the comparison of the calibration current and the calibration voltage drop.
