Abstract:
The invention relates to a method for steering a vehicle and to a steering system, which allows provision of a variable torque boost in response to the driver's steering request and an alteration of the position of the steered wheels initiated by the dynamic control system without these two actions impairing each other. The invention further allows the integration into the inventive method or the inventive steering system of further supplementary functions such as for example tracking of the vehicle in a simple manner and optionally with our without compensation for the steering feeling at the steering wheel.
Abstract:
The invention relates to a vehicle power steering, comprising a steering wheel (1) which acts indirectly through a steering column (3) upon a steering mechanism (5), an actuator (21) which acts independently from the steering wheel angle upon the steering mechanism (5) through the steering column (3), as well as a servo device (9) having a torque sensor (11) placed on the steering column (3) between the steering wheel (1), on the one hand, and the actuator (21) and the servo device (9), on the other hand. Consequently, the torque sensor (11) can measure directly the torque transmitted from the steering wheel (1) to the steering column (3) so that friction losses or play in the actuator (21) do not affect in any way the measurement of the torque and that the vehicle driver experiences directly a feeling of steering.
Abstract:
An electric screw actuator system, e.g. for an electrically driven and controlled steering device, comprises a screw actuator, an electric motor (2) engaging the screw actuator through a reduction gear mechanism (3), electronic operating means for operating the screw actuator electrically, and a mechanical back-up system for operating the screw actuator in the absence of electric power e.g. in the case of an electric power failure of in the case the electric power is switched off, maintenance, garage parking etc. The mechanical back-up system comprises a manually controllable operation member (4) and an electromagnetic coupling (6), said coupling disengaging the rotation member from the screw actuator in the case of nominal operation and availabitity of electric power, and engaging the rotation member with the screw actuator in the case of electric power failure.
Abstract:
A vehicle steering device has a steering wheel, a steering gear and an intermediate setting member (15) for allowing a controlled electromotor to intervene in the vehicle steering. The electromotor (19) has an input shaft (17) linked to the steering wheel and an output shaft (18) linked to the steering gear. In order to simplify the structure of the setting member (15), the electromotor (19) connected in series to an engageable and disengageable clutch (20) directly engages the input shaft (17) via a first gear (21) and the output shaft (18) via a second gear (22).
Abstract:
The invention relates to a method for calibrating the position of a feedback actuator (7) of a steer-by-wire steering system (1) of a road vehicle, wherein said method includes the following method steps: Moving the feedback actuator (7) to a first end stop of the feedback actuator (7) and from thereon to a second end stop; Recording the position of the two end stops and based on that determining a newly defined center position; Moving the feedback actuator (7) to the newly defined center position; and Storing the newly defined center position in a memory as an offset value of absolute steering wheel angle.
Abstract:
Steering system comprising a rotatably mounted steering member (14), the rotation of which is aimed at transmitting first command signals to a steering box, the steering box sets the steering angle of the wheels of a vehicle. The command member (14) comprises a star wheel (10) mounted inside said command member (14) in a rotatable manner with respect to said command member (14), there being a system of sensors (9) aimed at detecting the distance of the vehicle from reference points, such as objects, road strips or the like. Said sensor system is connected at least to said star wheel (10), said sensor system (9) comprising means for activating the rotation of the star wheel (10), which activation means are configured to rotate the star wheel (10) in the direction of said reference points.
Abstract:
The present disclosure relates to a steering system (410) for a vehicle, comprising a steering wheel arrangement (11) having a central axis (A) and being reversibly retractable in a direction towards a dashboard (400) of the vehicle and extendable in a direction away from the dashboard (400) of the vehicle. The steering wheel arrangement (11) includes a steering wheel (12) having a steering wheel rim (413) and at least one spoke (15), a steering wheel hub (14) fixedly connected with the steering wheel (12) by the at least one spoke (15) and extending from the steering wheel (12) towards the dashboard (400) of the vehicle, the steering wheel hub (14) and the steering wheel (12) being rotatable about a central axis (A). The steering wheel rim (413) has a non-planar configuration and has a total angle of rotation of 720° or less.

Abstract:
Die vorliegende Erfindung betrifft Lenksäule (1) für ein Kraftfahrzeug, umfassend eine relativ zu einer Trageinheit (3) um ihre Längsachse (L) drehbar gelagerte Lenkwelle (23), einen Umdrehungsbegrenzer (5) mit einem Endanschlag zur Begrenzung der Rotation der Lenkwelle (23), und einen über eine drehmomentschlüssige Verbindung mit der Lenkwelle (23) gekuppelten Drehsensor (7). Um eine erhöhte Betriebssicherheit zu ermöglichen, schlägt die Erfindung vor, dass der Umdrehungsbegrenzer (5) ein Grenzmoment aufweist, bei dessen Überschreiten die Rotation der Lenkwelle (23) über den Endanschlag hinaus freigegeben wird, wobei das Grenzmoment kleiner ist als ein maximales Übertragungsmoment der Verbindung zwischen Lenkwelle (23) und Drehsensor (7).
