Claim 0:
1. A method for actuating a vehicle steering actuator coupled to a steering gear, the method comprising:
providing a second control variable of a normal operation return function to the vehicle steering actuator, wherein the second control variable causes the vehicle steering actuator to generate a normal operation force that returns the steering gear to a defined position independent of a limit distance from an end stop;
determining whether the steering gear is below the limit distance from the end stop;
determining whether a hands-off autonomous parking function is inactive;
in case the steering gear is below the limit distance and the autonomous parking function is determined to be inactive: providing a first control variable of an end stop return function to the vehicle steering actuator, wherein the first control variable causes the vehicle steering actuator to generate a return force component in the direction of the defined position, which return force component is additional to the normal operation force; and
otherwise: operating the normal operation return function so that no additional return force component is generated.
