Description

STEERING WHEEL FOR A ROAD VEHICLE
FIELD OF THE ART
The present invention relates to a steering wheel for a road vehicle.
The present invention is advantageously applied to a steering wheels for a car, to which explicit reference will be made in the following description without because of this loosing in generality. PRIOR ART
Traditionally, the steering wheel of a car comprises an outer rim adapted to be gripped by the driver and a central hub, which supports the outer rim, is rigidly connected to the rim itself, is hinged to a steering column so as to rotate about a steering axis, and is mechanically connected to a steering device of the front wheels of the car. In other words, the central hub is angularly integral with the outer rim and thus rotates with the outer rim itself to change the steering angle of the front wheels of the car.
On the central hub of the steering wheel of a car there are inserted an increasingly high number of controls, such as, for example, the actuating levers of a servo-assisted transmission, the control buttons of a radio, the control buttons of a mobile telephone, the control buttons of a satellite navigator, one or more switches/selectors for modifying the dynamic features of the car (such as for example described in patent application WO2004087484A1) . However, the fact that the central hub of the steering wheel rotates along with the outer rim makes the use of the controls arranged on the central hub itself less intuitive, because the position of the controls carried by the central hub itself inevitably changes and thus the driver can no longer seek the various controls "by heart". Such drawback may appear of minor importance, but it must be considered that any distraction, also the smallest, is potentially dangerous when driving a car.
In order to solve the above-described drawback, it has been proposed to use a steering wheel whose outer rim is not angularly integral with the central hub, which is mounted in fixed position on the steering column; in this manner, only the outer rim rotates about the steering axis and the central hub always remains fixed. However, this configuration while simplifying the use of the controls carried by the central hub is not appreciated by all drivers (specifically the more elderly) who feel disoriented when they do not see the central hub rotating with the outer rim. DESCRIPTION OF THE INVENTION
It is the object of the present invention to make a steering wheel for a road vehicle which is free from the above-described drawbacks and which is simple and cost-effective to implement. According to the present invention a steering wheel for a road vehicle as claimed in the attached claims is made.
BRIEF DESCRIPTION OF THE DRAWINGS The present invention will now be described with reference to the accompanying drawings which show a non- limitative example of embodiment thereof, in which:
- figure 1 shows a perspective view, with parts removed for clarity, of a steering wheel for a road vehicle made according to with the present invention; and
- figure 2 shows a diagrammatic side view, with some parts removed for clarity, of the steering wheel in figure 1.
BEST MODES FOR CARRYING OUT THE INVENTION In figure 1, numeral 1 indicates as a whole a steering wheel adapted to control the steering of the front wheels (not shown) of a car (not shown) .
Steering wheel 1 comprises a central hub 2 comprising, in turn, a cup-shaped housing body 3, which is connected to a free end of a steering column 4 (shown in figure 2) , and defines a cavity (not shown) , which is arranged with its concavity facing towards the car driver, opens outwards at a front face of central hub 2, and is closed by a front cover 5 to define an airbag housing chamber (not shown) .
Steering wheel 1 further comprises an outer rim 6, which extends about central' hub 2, is coupled in angularly fixed manner to a steering shaft 7 (shown in figure 2) rotationally mounted with respect to steering column 4 about a rotation axis 8 (shown in figure 2), and is actuated by the car driver to control the steering of the front wheels of the car.
Steering wheel 1 is further provided with a pair of blades 9, which externally extend outwards from housing body 3 to allow the driver to control the operation of a servo-controlled transmission of the car. According to a variant (not shown) , each blade 9 displays light indicators consisting of, for example, LEDs and adapted to suggest to the driver the instant in which to operate blades 9 to shift gears.
Accommodation body 3 further supports a pair of control levers 10, which are accommodated within corresponding sunken seats obtained at a peripheral edge of the front face of housing body 3 and are arranged at opposite ends of housing body 3 itself. Each control lever 10 is rotationally coupled to housing body 3 so as to rotate with respect to housing body 3 about a fulcrum axis 11; furthermore, each control lever 10 is slidingly coupled to housing body 3 so as to perform, with respect to housing body 3 itself, straight shifts in a direction 12 parallel to axis 11. Control levers 10 allow the driver to control the operation of auxiliary devices of the car such as, for example, the direction indicators, the windscreen wipers and/or the external light devices. On the front face of housing body 3 there are mounted a switch 13 for starting the car engine, a thin- shaped, elongated LED display 14, and a pair of switches 15, each of which is rotationally coupled to the front face of housing body 3 so as to rotate with respect to housing body 3 itself about a rotation axis 16.
The front face of housing body 3 supports a pair of knobs 17, each of which may rotate about a rotation axis 18 and is provided with four selector buttons 19 symmetrically distributed about rotation axis 18. Each selector button 19 of a knob 17 allows the driver to select a corresponding function of the car, such as, for example, the radio volume or the climate control system fan; instead, the level of the function selected on a case-by-case basis by means of button 19 is selectively controlled by turning each knob 17.
Finally, steering wheel 1 is provided with a plurality of reconfigurable buttons 20, which face each other and are arranged between two selector buttons 21 which allow to select the functions associated on a case- by-case basis to reconfigurable buttons 20, as such, for example, different radio stations, or different CDs, or different internal lighting devices of the car. Preferably, each reconfigurable button 20 centrally presents a screen 22 adapted to display the function which may be activated by pressing reconfigurable button 20 itself. According to a different embodiment (not shown) reconfigurable buttons 20 are free from screens 22 integrated in reconfigurable buttons 20 themselves and the function of screens 22 is performed by a screen arranged in a dashboard of car 1 or by a HUD (Head Up Display) system which projects an electronic image onto the car windscreen.
According to a possible embodiment, reconfigurable buttons 20 may be used to store specific customised settings of the dynamic behaviour of the car and thus to rapidly call up such customised settings while race driving on a track.
According to a preferred embodiment, the function associated to each reconfigurable button 20 is further selected by a control unit of the car according to a current condition of the car itself. By way of example, if an on-board mobile telephone receives an incoming call, reconfigurable buttons 20 are automatically associated to the on-board mobile telephone control functions; if an on-board radio receives a traffic announcement then reconfigurable buttons 20 are automatically associated to the on-board radio control functions; if a rain sensor of the car detects the onset of rain, the reconfigurable buttons 20 are automatically associated to the wiper and the traction/stability control functions.
As shown in figure 2, central hub 2 is mounted on steering column 4 in central position with respect to outer rim 6 and is mechanically independent from outer rim 6 itself; furthermore, central hub 2 is rotationally mounted on steering column 4 so as to rotate by effect of the action of an actuator 23 carried by steering column 4.
Actuator 23 normally comprises an electrical motor and is controlled by a control device 24, which is connected to an angular position sensor which reads the angular position of outer rim 6 about rotation axis 8. In other words, control device 24 drives actuator 23 so as to control the angular position of central hub 2 about rotation axis 8.
Control device 24 is adapted to work in a first operating mode, according to which central hub 2 is maintained static regardless of the angular position of outer rim 6 about rotation axis 8. In other words, by activating the first operating mode, steering wheel 1 corresponds exactly to a steering wheel with fixed central hub.
Furthermore, control device 24 is adapted to operate in a second operating mode, according to which central hub 2 is rotated about rotation axis 8 in perfectly synchronous manner with outer rim 6 so that central hub 2 mimics at all times the angular position of outer rim 6 about rotation axis 8. In other words, by activating the second operating mode, steering wheel 1 corresponds exactly to a traditional steering wheel whose central hub is rigidly connected to the outer rim.
Finally, control device 24 is adapted to work in a third operating mode, according to which, when outer rim 6 is rotated about rotation axis 8 by a first rotation angle, central hub 2 is rotated about rotation axis 8 by a second rotation angle agreeing with and potentially different from the first rotation angle so that central hub 2 only partially mimics the angular position of outer rim 6 about rotation axis 8.
Normally, the value of the second rotation angle is proportional to the first rotation angle and depends on the actual angular position of outer rim 6 about rotation axis 8. According to a preferred embodiment, the second rotation angle is equal to the first rotation angle when the actual angular position of outer rim 6 about rotation axis 8 is lower than a threshold value, and the second rotation angle is lower than the first rotation angle when the actual angular position of outer rim 6 about rotation axis 8 is higher than the threshold value. Preferably, the higher the actual angular position of outer rim 6 about rotation axis 8 with respect to the threshold value, the smaller the second rotation angle with respect to the first rotation angle. In other words, by activating the third operating mode, steering wheel 1 presents intermediate features between a traditional steering wheel in which the central hub is rigidly connected to the outer rim and a steering wheel with fixed central hub; specifically, steering wheel 1 is similar to a traditional steering wheel in which the central hub is rigidly connected to the outer rim for small steering angles and more similar to a steering wheel with fixed central hub for higher steering angles .
Preferably, one of the two switches 15 is connected to control device 24 to select the required operating mode; in this manner, each driver may decide the operating mode which best suits his or her habits and driving style. By way of example, during sporty or race driving on a track, the first mode may be preferable because the driver' s attention is fully focused on driving the car, while during relaxed driving on roads open to the public, the second operating mode may be preferred because the driver' s attention also focuses on the accessory devices of the car (climate control system, radio, navigator, mobile telephone, etc.). According to the embodiment described in the accompanying figures, outer rim 6 is angularly integral with steering shaft 7; in other words, there is a direct mechanical connection between the front steering wheels of the car and outer rim β of steering wheel 1. According to a different embodiment (not shown) , outer rim 6 is not angularly integral with steering shaft 7, which is operated by an electrical actuator controlled by position sensor 25 according to the so-called "drive-by-wire" control technology.
Above-described steering wheel 1 presents many advantages, because it is simple and cost-effective to make and above all because it allows each driver to select the operating mode which best suits his or her habits and driving style. Furthermore, it is important to underline that also in the event of a failure to position sensor 25 or to actuator device 24 the safety of the car is never endangered because a possible failure of position sensor 25 or actuator device 24 does not effect the full and normal operation of outer rim 6 which is in any way the only steering control device.
