The disclosure relates to a method for operating a steering system of a motor vehicle. A voltage reserve is determined as a function of a compensation trajectory for a second actuating voltage and as a function of a modulation limit. A first actuating voltage with a fundamental frequency is determined as a function of the voltage reserve. A compensation voltage with a sixth-order harmonic with respect to the fundamental frequency of the first actuating voltage is determined. The second actuating voltage is determined for an inverter as a function of the first actuating voltage and as a function of the compensation voltage.

Method for operating a steering system, control unit for a steering system and steering system

An electromechanical actuator for rack-and-pinion steering includes a stator, rotor, and electronic system. The electronic system includes at least one first electronic sub-system and a second electronic subsystem, each operatively connected to the stator and the rotor. The at least one first electronic sub-system is arranged at least on a first circuit carrier plane and a second circuit carrier plane, and includes a first power output stage, a first control unit, and a first rotor position sensor arrangement. The second electronic sub-system is arranged at least on the first circuit carrier plane and a third circuit carrier plane, and includes a second power output stage, a second control unit, and a second rotor position sensor arrangement. The first, second and third circuit carrier planes are arranged perpendicular to an axis of rotation of the rotor, and are spaced apart from each other along the axis of rotation.

Electromechanical actuator comprising a redundant electronic sub-system

A steering system for a motor vehicle comprises an electric servomotor, as well as a water ingress detection device, at least one phase line of said servomotor being connected to a detection line for detecting the water level in a water-collecting area.

Steering system for a motor vehicle

A control device is configured for use in a steering system in a vehicle with electromotive servo assistance. The control device includes control device elements and electronic components for actuating a servo motor arranged in each control device element. The control device has chambers configured to accommodate the electronic components of the control device elements. The chambers are sealed off from one another in a watertight manner at least up to a defined filling level. The electronic components of the control device elements are split over different chambers.
