Abstract

A method for distinguishing intentional steering movements of a driver for influencing an intentional driving path of a motor vehicle from corrective steering movements of the driver as a reaction to unexpected deviations of the motor vehicle from the intentional driving path including ascertaining an instantaneous undisturbed motion of the vehicle along the driving path and calculating a reference value for a steering angle (SAR) corresponding to the ascertained, undisturbed motion of the motor vehicle or a reference value for a steering velocity (SVR) corresponding to the ascertained, undisturbed motion of the motor vehicle. Comparing the reference value(s) (SAR; SVR) with instantaneous steering-angle values (SA(t)) or instantaneous steering-velocity values (SV(t)) and ascertaining whether a difference between the instantaneous steering-angle value (SA(t)) and the corresponding reference steering-angle value (SAR) or a difference between the instantaneous steering-velocity value (SV(t)) and the corresponding reference steering-velocity value (SVR) exceeds a predetermined error-limit value (ΔE) which is established for the calculation of the reference values (SVR; SAR). If so, determining it is a corrective steering movement of the driver as a reaction to an unexpected deviation of the motor vehicle from the intentional driving path
