Method of actuating steer-by-wire vehicle steering drive mechanism
First Claim
1. A method for actuating a steer-by-wire steering drive mechanism by means of at least two triggerable redundant control motors (M1, M2) and gear units (G1, G2) downstream of the gear motors, by which a gear element (Z), connected to wheels (RA1, RA2), is driven simultaneously, wherein the two control motors (M1, M2) can be triggered independently of one another in such a way that by them, drive forces (F1, F2) in the same direction and of different amounts and drive forces (F1, F2) oriented in opposite directions and of equal or different amounts are generated simultaneously, to establish a difference, representing a tensing force, between the drive forces (F1, F2).

Abstract
A method for actuating a “steer-by-wire” steering drive mechanism by means of at least two triggerable control motors and gear units downstream of them, by which a gear element, connected to the wheels, can be driven simultaneously, is characterized in that the two control motors can be triggered independently of one another in such a way that by them both, drive forces in both the same direction and opposite directions and of equal or different amounts oriented in both the same and in opposite directions can be generated simultaneously.
