  • Patent number: 11878752
    Abstract: A method for operating a steering system includes providing an electromechanical steering assistance having several redundant control paths. Each control path includes a control unit, a power unit and a winding circuit of a servomotor. A correcting-variable unit is provided in each control unit in order to make a correcting variable available, depending on input variables. The correcting variables of all of the correcting-variable units are averaged. A set correcting variable is made available by each control unit, depending on the averaged correcting variable. A device for operating a steering system and a steering system for steering wheels of a motor vehicle, are also provided.

  • Patent number: 11565742
    Abstract: The invention relates to a method for adjusting a servo steering torque in a vehicle steering system, wherein the servo steering torque can be generated by an actuator of the vehicle steering system. The method comprises: receiving a driver's steering request, receiving a steering request from at least one driver assistance system, receiving at least one driving dynamics variable, determining a static state in which a change of the driver's steering request and the driving dynamics variable each is below a predetermined threshold, and if the static state has been determined, adjusting the servo steering torque by regulating, wherein a control variable for the regulation is determined based on a driver's steering request and the steering request by the driver assistance system.
