1. A railborne driver assistance device for lateral control of a vehicle, comprising:
a first processing unit configured to control a steering torque intervention by establishing a steering angle with a stationary control accuracy of an electrically supported steering system, and
a second processing unit configured to adjust the stationary control accuracy of the steering angle via an output accuracy request signal of the second processing unit to the first processing unit in such a way that there is a scaling of the stationary control accuracy between a lower and an upper threshold value,
wherein the second processing unit has an integrator comprising an input and an output, wherein the output of the integrator is connected to an input in a closed-loop manner with a weighting dependent on the accuracy request signal.
