Abstract

The invention relates to a power-assisted steering system of a motor vehicle with a steering handing device for specifying a steering wheel angle as a measure of a desired steering angle for at least one steerable wheel of the motor vehicle, a steering gear with a pinion, which converts a pinion angle, which depends on the steering wheel angle, into the steering angle of the at least one steerable wheel of the motor vehicle, superimposing means for producing an additional angle and for producing the pinion angle from superimposing the additional angle on the steering wheel angle and a servo drive with an electronically controllable hydraulic pump for realizing a variable moment support, the amount, flowing through the electronically controllable hydraulic pump being determined as a function of a rotational speed of the pinion angle ({dot over (.delta.)}.sub.G) and controlled by a control signal (i.sub.d) of a control device of the steering system.
