摘要

The superimposed steering system (1) has an overriding drive (2) provided for linkage of an angle fed by a driver on a gear unit input element (3) of the overriding drive, with an angle fed on another gear unit input element (4), to a total angle on an output element (5) of the overriding drive. A control and regulating unit (12) links the index impulse of an index sensor (6) with impulses of wheel speed sensors so that an absolute center position of the outlet element is detected.
