A method for torque control for an electromechanically assisted steering system of a motor vehicle is described. The method comprises the following steps:providing a modified controlled system, wherein the modified controlled system imitates desired mechanical properties of a controlled system;detecting at least one measured variable of the controlled system by a sensor;ascertaining an inertia compensation torque and/or a damping torque and/or a friction compensation torque by a modification controller based on the at least one measured variable;generating a torque demand of a steering feel controller for the electric motor by the at least one steering feel controller based on the at least one measured variable; andsuperimposing a torque demand of the steering feel controller with the inertia compensation torque and/or the damping torque and/or the friction compensation torque, by which a modified torque demand is obtained for the electric motor. Furthermore, a control unit, an electromechanically assisted steering system, and a computer program for carrying out the method are described.
