1. An apparatus for operating a driver assistance system for automated lateral guidance of a motor vehicle, comprising:
a control unit, wherein
(i) in a first operating state of the driver assistance system, the control unit is configured to:
determine a target position of a steering wheel of the motor vehicle based on a target steering angle of the motor vehicle which is stipulated by the driver assistance system in the first operating state, and
determine a quotient from the target steering angle which is stipulated by the driver assistance system in the first operating state, and from the target position which is determined therefrom, in order to determine a conversion factor; and
(ii) in a second operating state of the driver assistance system which is temporally sequential to the first operating state, the control unit is configured to:
by applying the conversion factor thus determined, determine a target steering angle equivalent based on the target position of the steering wheel which is stipulated by the driver assistance system in the second operating state,
by applying the conversion factor thus determined, determine an actual steering angle equivalent based on the actual position of the steering wheel which is determined in the second operating state, and
control an operation of the driver assistance system based on a target value/actual value comparison of the target steering angle equivalent and the actual steering angle equivalent.
