Embodiment Construction

[0029] figure 1 An exemplary steering system 22a is shown in simplified illustration. The steering system 22 a is configured as a conventional steering system with mechanical feedthroughs. Furthermore, steering system 22 a is designed as an electrically assisted steering system and thus has an electric power assist. Furthermore, steering system 22 a is provided for use in a vehicle (not shown), in particular a motor vehicle.

[0030] In the installed state, the steering system 22a is operatively connected to wheels 24a of the vehicle and is provided for influencing the direction of travel of the vehicle.

[0031] The steering system 22a includes a steering device. The steering device includes a steering handle 26 a , designed in the present case by way of example as a steering wheel, which is provided for exerting a manual steering torque. The steering handle 26a is therefore used for introducing steering presets and in particular for manually controlling the direction of ...

Abstract

The invention relates to a steering device, more particularly to the provision of electrical steering assistance, having at least one main control unit (10a-e), which is provided to control, in at least one normal operating state, operation of at least one electric motor (12a-e), and having at least one auxiliary control unit (14a-e), which is provided to control, in at least one faulty operatingstate in which a fault in and / or failure of the main control unit (10a-e) has occurred, operation of the electric motor (12a-e). According to the invention, the main control unit (10a-e) can be operated independently of the auxiliary control unit (14a-e) and the auxiliary control unit (14a-e) is set in the normal operating state to a passive operating mode.

Description

technical field [0001] The invention relates to a steering device according to the preamble of claim 1 . Furthermore, the invention relates to a steering system according to claim 11 . Background technique [0002] Steering systems with electric steering assistance in the form of servo steering are known from the prior art, in which an electric motor is used to generate the steering assistance. As a safety concept, for example, in the event of failure of electrical and / or electronic components of the steering system, a mechanical backup mode is often used, which is provided to enable steering even in the event of a failure of the steering assistance and to ensure a controlled and safe steering running. Switching to purely mechanical operation is achieved by switching off the main control unit with high-level software to control the operation of the electric motor and / or by deactivating the power electronics connected to the electric motor. However, a sudden deactivation o...
