Abstract

A method for actuating a vehicle steering actuator which is coupled to a steering gear, comprising: providing an end stop return function with which a first control variable for the vehicle steering actuator can be ascertained, on the basis of which a force that returns the steering gear in the direction of a defined position can be at least partially generated with the vehicle steering actuator; ascertaining whether the steering gear falls below a limit distance from an end stop; and if this is the case: actuating the vehicle steering actuator on the basis of the first control variable ascertained with the end stop return function, which control variable has a value above a threshold value; wherein, if the limit distance is not fallen below, no control variable is ascertained with the end stop return function or a control variable with a value not exceeding the threshold value.
