  • Method for detecting disturbance variables in a steering system, and steering system for a motor vehicle
    Patent number: 11668615
    Abstract: A steering system for a motor vehicle, having a steering column, an electromechanical steering assistance apparatus, a sensor which is assigned to the steering column and is configured to sense a torque and a rotational angle of the steering column, and a regulator, wherein the electromechanical steering assistance apparatus comprises a motor having an angular position encoder which is configured to sense the motor rotational angle of the motor, wherein the regulator is configured to determine a torque of the electromechanical steering assistance apparatus, and wherein the regulator is also configured to determine a disturbance variable, which gives rise to an undesired steering sensation, in the steering system by means of a Kalman filter.

  • Method for detecting the presence of hands on the steering wheel
    Patent number: 11465679
    Abstract: A method for detecting the presence of a driver's hands on the steering wheel of a motor vehicle is described. By means of a mathematical model, at least one part of a steering system of the motor vehicle is modeled. In addition, a rotational angle of a lower end and/or an upper end of a torsion bar of the steering system is determined. A torque acting on the torsion bar is determined by means of a measuring device and a total torque acting on the steering wheel and a rotational angle acceleration of the steering wheel are estimated by means of a Kalman Filter.
