Abstract:
A method for operating a steering system of a motor vehicle having at least one steerable wheel, the steering system including a superposing gear assembly and an actuator for supplying an angular movement (&dgr;M) supplied by said actuator to said superposing gear assembly, the method comprising the steps of:providing pregiven steering stops (C) within which said steerable wheel is turned; superposing a steering movement (&dgr;L), which is initiated by the driver of said vehicle, and said angular movement (&dgr;M), which is initiated by said actuator, in said superposing gear assembly to generate a steering movement (&dgr;V) of said steerable wheel within said pregiven steering stops (C); reducing said angular movement (&dgr;M) in accordance with a pregivable or pregiven characteristic in a run-out zone (A, B) before reaching one of said pregiven steering stops (C); providing a switchoff threshold (D) shortly after the end (B) of said run-out zone (A, B) forward of said pregiven steering stops (C); and, when said switchoff threshold (D) is exceeded, braking said actuator to standstill by a corresponding supply of current and then switching said actuator off.
