    • In order to implement a steering feel, for SbW systems and EPS systems having a control concept for controlling the steering torque, by generating a target steering torque (torTB) that can be adapted to different steering systems or vehicle types or requirements, and for which the resultant steering feel comprises in all driving states and driving situations an equivalent or improved steering feel relative to hydraulic and electromechanical steering systems currently on the market, the invention proposes that a base steering torque (torB) is determined as a function of a force (torR) acting externally and a vehicle speed (velV); a damping torque (torD) is determined as a function of the steering speed (anvSW) and the vehicle speed (velV); a hysteresis torque (torF) is determined as a function of the steering speed (anvSW) and the vehicle speed (velV), a centering torque (torCF; torC) in the direction of the straight-line position is determined as a function of the steering wheel angle (angSW) and the vehicle speed (velV); and the base steering torque (torB), the damping torque (torD), the hysteresis torque (torF) and the centering torque (torCF; torC) form individual components, the target steering torque (torTB) being determined as a function thereof.
