  • Method and steering control apparatus for determining a correcting variable for adjusting servo steering torque in a vehicle steering system
    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.
