Abstract
The disclosure relates to a method for cooperative steering angle control for an electromechanically assisted steering system of a motor vehicle. The steering system has electromechanical steering assistance with an electric motor and at least one controller. The controller has two degrees of freedom, a first of the two degrees of freedom being associated with a torque exerted on a steering wheel, and a second of the two degrees of freedom being associated with a steering angle. The method comprises the following steps: determining a driver torque; ascertaining a reference steering wheel torque by a dynamic feedforward; receiving a reference steering angle; feeding the reference steering angle into a control loop; feeding the determined reference steering wheel torque into the control loop by the dynamic feedforward; and ascertaining a steering wheel torque and a steering angle by the control circuit (). A control device for an electromechanically assisted steering system of a motor vehicle is also disclosed.
