An overriding drive for an overriding steering system, wherein a steering angle inputted by the driver can be overridden by another angle by a control according to correcting variables and the transmission ratio can be modified, and which is characterized in that the overriding drive is locked electromechanically in dependence on further correcting variables representative of an operating state of the vehicle.
