Abstract

Method and control device for determining a steering angle of a motor vehicle, wherein a theoretical steering angle is calculated by a vehicle model and a measured steering angle is determined with a steering angle sensor, and the difference between the measured and theoretical steering angles is determined, wherein at least one data record including a number of successive measured values is acquired, and a correction constant for the measured steering angle is determined from the mean value of the differences between the theoretical steering angle and the measured steering angle. According to the invention, a confidence level, which changes incrementally between successive data records, is calculated by travel conditions present during the acquisition of the data record and/or an analysis of the data record.
