Description
Steering arraqement The invention relates to a steering arrangement for a twowheeied vehicle and a method for detecting a steering angle by means of the steering arrangement.
S
Prior Art
Steering arrangements which include a steering angle sensor used to detect a steering angle are nowadays very common in motor vehicles. The detection of steering angles is important primarily in vehicle dynamic stability systems, such as for exampMe in the Eectronic Stability Program (ESP). In addition to ESP, systems such as electric powoNassisted steering, active steering, electrofl hydrauilc poweras&sted steerIng, bending light systems or Adaptive Cruise Control (ACC) use information relating to the steering angle. is
Steering angle sensors are known from the Prior Art and comprise a rotor having encoded discs, the code of which can he scanned by a scanning unit. The code of the encoded discs is conventionally produced by teeth of different widths having interposed tooth gaps.
Document DE 10 2004 004 023 Al describes a steering angle sensor having a main rotor which can be coupled in a rotationally synchronous manner to a steering column or steering wheel and can be rotated about the rotational axis of the steering column. The steering angle sensor further includes a first scanning unit for scanning the rotational angle position of the main rotor and a second scanning unit for scanning the rotational angle position of the additional rotor, wherein the additional rotor can be rotated about the rotational axis of the steering column and at least one transmission member driven by the main rotor is provided for driving the additional rotor.
The proposed arrangement is disadvantageous in that the sensor, by using a I. main rotor, an additional rotor and a transmission member connecting the two rotors, takes up a comparatively large amount of space, whereby an appUcation in twowheeled vehicles is hindered. Another disadvantage is that, when being operated for a long period of time, the rotors can show signs of wear by way of the effects of dirt or abrasion.
It is thus the object of this invention to provide a steering arrangement having a steering angle sensor, in which signs of wear can be minimised and which can be instaDed in a twowheeled vehicle in a space-saving manner. 1.0
Disclosure of the invention
In accordance with a first aspect of the present invention, there is provided a steering arrangement for a two-wheeled vehicle which includes a frame in which a steering tube is guided, wherein the frame comprises an opening, in the region of which an angle sensor is disposed, and wherein a movement element corresponding to the angle sensor is disposed on the steering tube in the region of the opening on the frame, wherein the angle sensor and the movement element are disposed in a contacUess manner with respect to each other.
In accordance with a second aspect of the present invention, there is provided a method for detecting a steering angle in a twowheeled vehide, by means of a steering arrangement in accordance with the first aspect.
Advantageous embodiments are provided in the dependent claims and the
description.
It is proposed to provide a steering arrangement for a twowheeled vehicle which includes a frame, in which a steering tube is guided, and a sensor unit. For its part the sensor unit includes an angle sensor and a movement element corresponding to the angle sensor. In order to ensure that the sensor unit functions correctly, the angle sensor is attached to the steering arrangement in an immovable manner whUst the movement element is to be attached so that during steering, La, when a steering wheel of the twowheeled vehicle undergoes a rotationS movement, the movement element also rotates.
In one embodiment, the angle sensor is attached to the frame and the corresponding movement element Es attached to the steering tube, wherein the angle sensor and movement element are disconnected fmm each other, i.e., are disposed in a contaciless manner. 1 0
Signs of wear are avoided by this contactless arrangement of the angle sensor and movement element. In contrast to conventional steering angle sensors, which include rotors or transmissions which wear out over long periods of use, in the steering angle sensor presented herein, there is no need to provide such rotors or transmissions which means that a spacesaving construction is permitted.
Furthermore, the steering angle can be detected via a magnet as the movement element and a corresponding angle sensor. In order to faciUtate attachment to the steering tube, provision is made to use a bent N1&polarised magnet, the curvature of which corresponds to the curvature of the steering tube. In one embodiment, the bent magnet corresponds to a bar magnet, i.e.. the north pole is located on one half and the south pole is located on the other half, wherein the virtual separation line between the north and south poles extends in parallel with the steering tube. (However, other designs of magnets are also feasible.) This magnet is simply connected to the steering tube in a non-positivelockEng manner by a clamping arrangement, e.g., by a clamping ring. In a further embodiment, a receptacle or pocket is provided on the steering tube, in which the magnet can be inserted.
In order for it to be possible to measure the steering angle by way of the angle sensor, it is extremely important that during steering only the magnet moves or rotates whflst the posifion of the angle sensor does not change. This is ensured by virtue of the fact that the angle sensor is not attached to the steering tube but rather to the frame of the steering tube. In one embodiment, an opening is provided in the frame of the steering tube, in which the angle sensor is installed.
The opening thus connects an inner side of the frame to an outer side thereof so that the angle sensor can be mounted via the outer side of the frame e.g., after the steering tube has been inserted into the frame. Furthermore, the opening can be farmed only on the inner side of the frame as a recess which means that the angle sensor is mounted prior to insertion of the steering tube into the frame.
Moreover, the angle sensor can be attached in an opening. wherein the opening is asnmetricaL This means that owing to its dimensions the opening aVows the mounting of the angle sensor only from one side, La, only from the inner side or outer side of the frame.
In oter to aVow a high degree of measuring accuracy, the angie sensor is disposed opposite the magnet. This means that a virtuS connection line between the angle sensor and the magnet forms an angle a with respect to the hngitudinal axis of the steering tube! where for example 60 c a c 120°. The magnet is furthermore directed towards the angle sensor such that in the non steering state the transition between the north pole and south pole of the magnet, i.e., the region with the best homogeneity of the magnetic field, is located in front of the angle sensor.
It can also be provided that the HaD effect is used to measure the steering angle.
The Hall effect describes the occurrence of an electrical voltage in a conductor having current flowing through it and being located in a stationary magnetic field, The voltage thus drops perpendicularly with respect to the current flow direction and also to the magnetic field direction at the conductor. This voltage is called the Hall voltage.
If a simple HaU sensor has a current flowing through it and is moved into a magnetic field extending perpendicularly thereto, it provides an output voltage which is proporhonal to the product of the magneUc fi&d strength and current.
S Moreover, the signal is also temperaturodependent and can have an offset. In analogue Ha sensors, the current is controlled and the temperature dependency of the signal, the offset and any non..linearities are compensated for.
In digital Hall sensors the signal of an analogue HaD sensor is converted into a digital signal via a comparator.
In the case of HaD sensors which are used in the steering arrangement presented herein, the change in the magnetic field is measured in dependence upon the rotation of the magnet. An angle$eleted output signal is thus produced by a control unit of the sensor unit. For safety reasons, the sensor unit can supply redundant signals.
The thus determined steering angle can be used in various areas. For example, a determination can be made as to when a ne change is taking place or is completed so that the indicator can be switched on or off. Furthermore, the detected steering angle can also be used by further control devices, e.g., the Electronic Stability Program (ESP) or the traction control system.
In one embodiment of the presented steering arrangement, the sensor unit is disposed on the steering tube or on the frame of the steering tube between two fork bridges. The region on the steering tube between two fork bridges is particularly advantageous since it offers enough space for the sensor unit and aHows attachment prior to mounting the steering tube on the motorcycle.
Further advantages and embodiments of the invention can be seen from the
description and the attached drawings.
it is understood that the aforementioned features and the features stiU to be explained hereinafter can be appUed not only hi the respective stated combination but also in other combinaUons or in isolation without departing from the scope of the present invention.
By way of example only, a specific embodiment of the present invention will now be described with reference to the accompanying drawings, in whbh: Figure 1 schernaticay shows an embodiment of a steering arrangement in accordance with the iriventbn having a steering angle sensor.
Figure 2 schematicafly shows the measuring principle of the steering angle sensor.
Embodiments of the invenUon The invention is schematicafly iHustrated in the drawings with the aid of embodiments and wiB be described in detail hereinafter with reference to the drawings.
Figure 1 schematically illustrates a steering arrangement I in accordance with the invention having a steering angle sensor 2. The steering arrangement I includes a steering tube S and a frame 6 in which the steering tube 5 is guided.
The frame 6 is disposed between two fork bridges. The steering arrangement 1 further comprises a sensor unit 2 for detecting a steering angle, which unit includes an angle sensor 3 and a magnet 4 as a movement element. The magnet 4 is illustrated as a bent N/Spolarised magnet which is connected to the steering tube between the two fork bridges in a non-positive--locking manner via a clamping ring 7.
The angle sensor 3 is, in contrast, disposed on the frame 6 of the steering tube 5 opposite the magnet 4. The angle sensor 3 is disposed in front of the magnet 4 in the direction of travel in Figure 1, wherein another arrangement, Le.. behind or next to the magnet in the direction of travel, is also feasible. In order to attach the angle sensor 3 to the frame 6, an opening is provided in the frame 6, in which the angle sensor 3 is instafled in a positiv&ocking manner. The magnet 4 as a bent permanent magnet is to be disposed with respect to the angle sensor 3 such that the distances of the north pole and south pole to the angle sensor 3 are approximately identical, i.e., the transition beveen the north pole and south pole should be opposite the angle sensor 3. This transition has a high homogeneity of the magnetic field, whereby in a particularly precise manner the angle sensor 3 can detect small changes in the magnetic field which are caused by the magnet 4 rotating.
In this configuration, the magnet 4 is formed as a curved bar magnet but other suitable configurations are also Feasible.
The steering angle is determined using the Hall effect. The Hall effect describes the occurrence of an electric voltage in a conductor which has a current flowing therethrough and is located in a stationary magnetic field. The voltage thus drops perpendiculady with respect to the current flow direction and also to the magnetic field direction at the conductor. Therefore, if a Hall sensor has a current flowing through it and is moved into a magnetic field extending perpendicularly thereto, it provides an output voltage which is proportional to the product of the magnetic field strength and current. If the strength of the magnetic field is varied, e.g., by rotation of the magnet producing the magnetic field, then the variation in the strength of the magnetic field is registered, wherein the Hall sensor outputs a corresponding electric signal. The Hall voltage is thus proportional to the strength of the magnetic field.
In the case of the rotatory magnetic field detection, the magnetic field is broken down into its vertical, i.e., Y direction, component (By) and its horizontal, i.e., X
S
direction, component (By). The course of the magnetic field strength in the X or Y directions is thus displaced by 90. As shown hi Figure 2, the magnefic field strength in the X direction describes a cosine curve in dependence upon a rotational angle, whilst the magnetic field strength in the Y direction describes a sine curve. The double arrow 10 indicates a rotation. Owing to this displacement of the two magnetic field components by 90°, the formation of the arctan (BdB) by a control unit, also referred to as IC or integrated circuit (not shown) in Ha sensors, aVows the generation of a linear signal 12 as an output which is used to easily determine the steering angle. By virtue of the fact that the steering angle is calculated from the X and Y components of the magnetic field strength, measuring errors are minimised which means that even smafi steering angles can be detected with a high degree of accuracy. Moreover, calibration in straight travel is not required. Equally, the zero point does not have to be fixed hi such a steering angle sensor since a relative variance, and not an absolute variance, of
the magnetic field strength is measured. a
