- FIG. 1 represents the arrangement of a control module 10, produced according to the state of the art, which is interposed axially between the front dashboard 12 and the steering wheel 14 of the vehicle,
- the control module 10 here comprises two control devices 16, 18 which are controlled by the front ends 20, 22 of two levers
- the levers 24, 26 have an elongated body
- the two control devices 16 and 18 have a minimum thickness which here corresponds substantially to the thickness El of the housing 32 of the control module 10,
- the command module 10 also includes an instrument or satellite 33 for controlling a media player such as a car radio.
- the satellite 33 here has the shape of a housing extending substantially parallel to the lever 24 out of the side of OITE 28 of the housing 32, as seen in FIG 1.
- the steering wheel 14 mainly consists of a rim 36 and a central hub 38 which is extended forward by a protrusion 40 in which, for example, an airbag is arranged.
- the prominence 40 may also be due to the drive device of the steering column in the case of a steering wheel with a fixed hub.
- the two levers 24, 26 are inclined rearward relative to the transverse plane of the housing 32, so that their free ends rear 42, 44 are located near the rim 36 of the steering wheel 14,
- the driver can control the control devices 16, 18 by actuating the levers 24, 26 by their associated rear free ends 42, 44,
- the actuation of the free ends 42, 44 of the levers 24, 26 may consist of rotational movements of the levers around vertical axes VI, V2 and / or horizontal axes Hl, H2, each position in which the levers 24, 26 make it possible to control functions such as the wiping speed or the lighting mode of the road.
- the extreme angular positions of the lever 24 which are separated by a angle a,
- the rear free end 42 of the lever 24 travels the path Tl between its two extreme positions, when the lever 24 pivots about the vertical axis VI,
- the clearance Jl In order to provide the driver of the vehicle with maximum safety in the event of an impact, ie to allow the steering wheel 14 to be retracted forwards, provision is made for a space or clearance Jl between the front face 45 of the housing. 32 and the rear face 50 of the dashboard 12. In practice, the clearance Jl must be of the order of 60 mm.
- the distance Dl between the flywheel 14 and the rear face 50 of the board 'edge 12 should not be too large
- the distance Dl corresponds to the sum of the thickness El of the housing 32 of the control module 10, the axial clearance Jl, and the depth PI which corresponds to the distance between the median plane of the rim 36 of the steering wheel 14 and the face before 48 of prominence 40.
- the thickness E1 of the housing 32 of the control module 10 is mainly determined by the dimensions of the control devices 16, 18.
- the depth PI of the prominence 40 is in turn determined by the size of the airbag and its deployment device (not shown). It is advantageous to increase the axial play Jl so as to increase the axial retraction distance of the steering wheel 14 and of the control module 10 in the event of an impact, which improves the safety of the driver. In known systems such as that shown in FIG. 1, the increase in the axial play Jl necessarily results in an increase in the distance Dl, since the thickness El and the depth PI are at their minimum and they are determined by technical constraints on the size of their components.
- the increase in the distance D1 is undesirable since it results in an increase in the axial size of the driving position.
- the invention proposes that the lateral parts 28, 30, in which the control devices 16, 18 are arranged, are oriented in directions dl, d2 inclined rearward relative to the orientation generally transverse of the housing 32.
- the thickness of the central part 34 of the housing 32 no longer depends on the size of the control devices 16, 18,
- the axial thickness E2 of the central part 34 of the housing is reduced. This increases the axial play J2 which separates the front face 45 of the housing 32 and the rear face 50 of the dashboard 12, without modifying the distance Dl between the steering wheel 14 and the rear face 50 of the dashboard 12 ,
- the invention allows. thus improving the safety of the vehicle in the event of an impact, by allowing the steering wheel 14 to be retracted in the area released by the clearance J2 which extends between the front face 45 of the housing 32 and the rear face 50 of the dashboard. 12.
- the prominence 40 of the steering wheel 14 is generally frustoconical in shape with its apex oriented towards the front.
- the inclined directions dl, d2 of the lateral parts 28, 30 can advantageously be inclined in directions substantially parallel to those of the lateral faces 52 of the prominence 40, this makes it possible to improve the aesthetics of the driving position, in particular by integrating a system control 64 of the media diffuser in an end face of the right lateral part 28, and this makes it possible to optimize the size of the steering wheel 14 and of the control module 10,
- the general direction of the levers 24, 26 is also advantageously substantially parallel to the orientation of the associated lateral parts 28, 30, that is to say that they extend in the extension of the parts 28, 30.
- the invention also makes it possible to improve the ergonomics of the control module 10.
- the levers 24, 26 are of the type with low clearance, that is to say that the paths T2 traversed by the rear free ends 42, 44 levers 24, 26 between the two extreme positions of actuation of the associated control (shown in thin lines for the lever 24 in Figure 2) are reduced. This is mainly due to their short lengths.

- the voice recognition device 60 is composed of a microphone connected to a processing system which makes it possible to recognize instructions provided by voice by the driver of the vehicle.
- the device 60 is here located under the control lever 26.
- the control system 62 also called radio satellite, here comprises a block 64 for controlling the sound of the radio which is composed of two upper 66 and lower 68 buttons and an intermediate button 70.
- the control system 62 also includes a member for selecting the frequencies of reception of radio waves,
- the selection member is a thumb wheel 72 shown on a larger scale in FIG. 4,
- the thumb wheel 72- is rotatably mounted around an axis A sensiblemen orthogonal to the direction dl inclined of the transverse part 28 and of the lever 24 and the wheel 72 extends generally in a substantially vertical plane.
- it has indexed positions which each correspond to a function such as the selection of the reception frequency of the radio waves.
- the control module 10 can also include a tilting member 74 which makes it possible to select the accessory controlled by the control system 62.
- a tilting member 74 which makes it possible to select the accessory controlled by the control system 62.
- the tilting member 74 is here, by way of example, a button which makes it possible to select the piloted accessory each time it is actuated.
- the levers 24, 26 include rings selection which are pivotally mounted along the longitudinal axes of the bodies of the corresponding levers 24, 26 which are here aligned with the directions dl and d2 inclined. The rings are movable between at least two angular positions each corresponding to the selection of a different function or to a rest position,
- the lever 24 can thus include first and second rings 76 and 78,
- the position of the lever 24 can allow the actuation of the wiper arm, as well as the adjustment of the wiping speed,
- the first ring 76 which is located at the rear free end of the lever 24 can activate a device for spraying the windshield of the vehicle with a washing liquid or can allow alternating scanning of the wiper arm of the rear window.
- the second ring 78 of the lever 24 makes it possible, for example, according to its angular position, to adjust the timing of wiping, or the sensitivity of the rain sensors.
- lever 26 can control the lighting of the road. It also has first and second rings 80 and 82 which allow the type of road lighting to be selected.
- the first ring 80 which is located at the rear free end of the lever 26 can allow the activation and deactivation of the front and rear fog lights
- the second ring 80 can in turn allow the selection of the projector which must be activated, that is to say, for example, the low beam or the high beam, it can also allow the activation of the automatic lighting of the headlights in particular as a function of the exterior brightness of the vehicle,
