Abstract

A method for calibrating a sensor system, including: providing at least one first sensor unit and one second sensor unit, providing first correction data for the first sensor unit on the basis of measuring signals of the first sensor unit, providing second correction data for the first sensor unit, in the case of an activated second sensor unit, on the basis of measuring signals of the first sensor unit and on the basis of measuring signals of the second sensor unit, determining a first quality parameter for the first correction data and a second quality parameter for the second correction data, determining present correction data for measuring signals of the first sensor unit based on the correction data having the highest of the two determined quality parameters, and calibrating the first sensor unit by correcting first measuring signals on the basis of the present correction data.
