Description

The invention relates to a manual control device, in particular a steering wheel control device, in particular for a motor vehicle.

In this field, it is known to have manual control devices on the arms of a steering wheel used for displaying information on the dashboard or for controlling various driving assistance or entertainment systems. occupants of the vehicle.

These are in particular devices comprising a button which can be actuated impulsively in a transverse movement, in a first direction or in a second direction opposite to the first direction, this using the thumb, while the driver is holding his wheel. Devices have also been proposed in which the button can also be actuated in an impulse fashion by depressing the button. In other words, in these devices, the same button can be actuated either by transverse movement, in one direction or another, or by pressing.

These devices also include contactors configured to be activated during transverse movement and / or when the button is pressed. Depending on the activated contactors, an electrical signal is transmitted to a processing unit which will then trigger the desired action by sending an order to an actuator on a display or one of the systems mentioned above.

However, in known devices of this type, the contactors activated when the button is pressed are all contactors already stressed during a transverse movement of the button. This represents a weakness in terms of reliability. Indeed, pressing the button can generate the transmission of incorrect signals to the processing unit. For example, if the combination of contactors to be activated in the event of the button being pressed is not activated due to too great a dispersion in the dimensioning of the parts in question, premature wear of these or insufficiently controlled operating clearances, only the contactor (s) corresponding to a transverse movement are likely to be. In this way, pressing the button can be wrongly interpreted as a transverse movement.

The object of the invention is to at least partially overcome the drawbacks mentioned above and in this sense proposes a manual control device, in particular a steering wheel control device for a motor vehicle, said device comprising a control button, said device being configured to selectively authorize actuation of the button by depressing as well as by transverse displacement in a direction, called positive, and a direction, said negative, relative to a rest position, said device further comprising contactors configured to be activated during one and / or the other of the button actuations, said device being configured so that at least one of said contactors, said first, is specifically activated when the button is pressed.

Thus, by providing a dedicated contactor, intended to be activated when the button is pressed and only on this occasion, the risks of misinterpretation of the movements of the button, in particular when pressed, are limited, which only causes the depression activation of the dedicated contactor or the dedicated contactor and other contactors.

As illustrated in the various figures, the invention relates to a manual control device, in particular for a motor vehicle. It may in particular be a steering wheel control device.

As more particularly illustrated in FIG. 1, the invention also relates to a steering wheel 1 equipped with such a device. The steering wheel 1 comprises one or more arms 2, connecting a center 4 of the steering wheel to its circumference 6. The said arm or arms 2 are equipped with a device 8 for manual control according to the invention. The steering wheel illustrated comprises two arms 2, each provided with a control device 8, at least one or even both being in accordance with the invention. Other embodiments are possible, the steering wheel being able to comprise a different number of arms and a different number of control devices, including one or more arms without a control device.

Said manual control device 8 according to the invention comprises a control button 10. Said button 10 is intended to be actuated by a thumb of the driver. Said button 10 is here located on the front of the steering wheel. Such an actuator 10 can be used for a large number of functionalities at the choice of the automobile manufacturer, such as the display of information on the dashboard, the setting of values, in particular of the speed in an automatic control system. speed, or the selection of various parameters in other driver assistance or entertainment systems for vehicle passengers.

As illustrated in FIG. 2, said manual control device 8 is configured to allow actuation of the button 10 by transverse displacement in a direction, called positive, and a direction, said negative, on either side of a position of rest. The rest position is that illustrated in the figure. The movement in a positive direction is illustrated by the arrow marked 12 and the movement in the negative direction is illustrated by the arrow marked 14. In a position of the steering wheel corresponding to a straight path of the vehicle, the movement in the positive direction corresponds to a moving up and moving in the negative direction corresponds to moving down.

Said manual control device 8 is configured to allow such transverse movement, for example, by rotating the button 10, in particular of the order of 10 to 20 °, in one and / or the other direction, with respect to to its rest position. Said device is here configured so that the rotation of the button 10 takes place around an axis extending substantially parallel to the arm 2 of the steering wheel.

As more particularly illustrated in the following figures, said manual control device 8 is further configured to authorize actuation of the button 10 by depressing, in particular from the rest position. More specifically, said device is configured so that the button 10 can either be pressed or moved transversely. In other words, the device is configured to allow:

an actuation of the button 10 by pressing while its transverse movement is prohibited, in particular blocked, and

- An actuation of the button 10 by transverse movement while its insertion is prohibited, in particular blocked.

Such actuation with blocking of one of the movements while the other movement is authorized is particularly illustrated in FIGS. 5 as well as 12 to 15 and will be detailed below.

As more particularly illustrated in FIGS. 3 and 6, said manual control device 8 further comprises contactors 20 configured to be activated during one and / or the other of the actuations of the button 10. The one or more contactors 20 are, for example, configured to authorize a flow of electric current in a branch of a control circuit, not illustrated, when they are activated by the corresponding actuation of button 10 and to interrupt the flow of current in said branch otherwise. Thus, a control system comprising said circuit can determine in the form of an electrical signal the nature of the actuation of the button 10, namely pressing, transverse movement in the positive direction or transverse movement in the negative direction, depending on the branch or branches of the circuit in which the current flows. Said control system is advantageously configured to process said signal and generate the desired resulting action such as the display of information, the setting of a value, the activation of a vehicle organ or any other actions.

The contactors 20 comprise, for example, one or portions of a deformable membrane 22 of said control device 8. The portion or said portions of said deformable membrane 22 are here defined by activation zones 24, in particular in the form of a dome, possibly flattened. Said activation zones 24 are configured to be selectively deformed, for example depressed, when the button 10 is actuated. In the embodiments illustrated in FIGS. 3 and following, the membrane 22 comprises other domes which correspond to manual control device, not shown and which may be of another nature than that manual control device according to the invention, such as a simple push button, impulse or not.

Said manual control device 8 according to the invention further comprises here a printed circuit board 26 or PCB according to the associated acronym (for Printed Circuit Board), illustrated only in Figure 6. Said printed circuit board 26 and said membrane 22 advantageously extend parallel to one another. Said printed circuit board 26 comprises, for example, switches 28, disposed along the branches of the control circuit. Said activation zones 24 are configured to selectively close the switches and authorize the flow of current. For this, said activation zones 24 are here configured to come, following their depressing, into contact with said switches 28 by establishing an electrical contact between two conductors distant from said switches 28.

Said control device is advantageously configured so that the actuation of the button 10 corresponding to the transverse displacement and / or the depressing of said button 10 is impulse, that is to say, allows the button to return to its rest position as soon as that the effort exerted by the user on the button 10 ceases. This is obtained here, for example, thanks to the membrane 22, provided elastically deformable in this direction. Other elastic return members, such as springs, may be used, alternatively or in addition, to bring the button 10 back to the rest position after transverse movement and / or depression by the user.

According to the invention, said device is configured so that at least one of said contactors 30, said first, is specifically activated when the button 10 is depressed. Arrange in this way one or more contactors dedicated to the pressing button 10 improves the reliability of the device.

For their part, one or more of the other contactors 32, called second, are configured to be activated during the transverse movement of the button.

According to the embodiment of Figures 3 to 5, the control device comprises a single first contactor, not illustrated, two second contactors 32, one corresponding to the transverse movement of the button 10 in the positive direction and the other in the direction negative. The first contactor is located between the second contactors 32.

According to the embodiment of Figures 6 and following, the control device comprises two first contactors 30 and two second contactors 32, one corresponding to the transverse movement of the button 10 in the positive direction and the other in the negative direction. The first and second contactors 30, 32 are respectively arranged along transverse lines, in particular orthogonal, to one another. In this mode, as a variant, a single first contactor is also possible.

In a first case, the manual control device 8 is configured so that pressing the button causes activation of the first contactor (s) and the second contactor (s) 32 simultaneously. This is the case in the embodiment of Figures 3 to 5. The organs involved in this direction are detailed below.

According to another scenario, said manual control device 8 is configured so that the transverse movement of the button 10 causes activation of the second contactor (s) 32 without activation of the first contactor (s) 30. In this other case, said device is in further advantageously configured so that pressing the button 10 causes activation of the first contactor (s) 30 without activation of the second contactor (s) 32. This is the case in the embodiment of FIGS. 6 et seq. The organs involved in this sense are detailed below.

As illustrated in Figures 3 and following, said manual control device advantageously comprises a support 40. Said manual control device may also include a cover 60 (visible in Figure 2) closing said support 40, said cover 60 having a window through which the button 10 opens, at least in part, to allow its actuation by the user.

In the embodiments illustrated in Figures 3 and following, the support 40 is intended to further accommodate the buttons of the manual control device already mentioned above and not necessarily corresponding to devices according to the invention. It may include for this wells 41, arranged next to an area for the button 10 of the manual control device 8 according to the invention.

The latter also advantageously comprises one or more movable elements 42 relative to the button 10. Said device is configured so that the depression of the button 10 and / or its transverse displacement cause the actuation of the first and / or second contactors 30 , 32 by movement, in particular by translation, of said mobile element or elements 42, in said support 40. In other words, here, the mobile element or elements are configured to push in at least some of the activation zones 24 of the membrane 22. It a mobile element 42 is preferably provided by contactor 20. The direction of translation of said mobile elements 42 is, for example, substantially orthogonal to a plane of extension of the membrane 22. Such mobile elements 42 promote more reliable activation of the contactors 20 .

The movable element or elements 42 include, in particular, needles and / or pins 44.

Said pin or pins 44, on the one hand, and said button 10, on the other hand, are configured to slide relative to one another during the transverse movement of the button 10. In other words, during the transverse movement of the button 10, in particular during its rotation, the area of the pin or pins 44 in contact with the button 10 changes as the button 10 rotates, this in order to allow the translation of said pins 44 along an arm lever dependent on the distance between the axis of rotation of the button 10 and the direction of translation of the pins 44.

To facilitate such sliding, the said pin or pins 44 comprise a head 46 configured to slide on the button 10. The head 46 advantageously has in this sense a rounded shape.

Said pin or pins 44 comprise a foot 48, opposite their head 46, for cooperating with the first and / or first contactors 30, 32. The foot 48 advantageously has a flared shape (case of the mode illustrated in FIGS. 6 and following) ). Said flared shape ends, for example, with a flat surface thereby giving the pins 44 a general shape of valve.

From the above, it is understood that the manual control device is configured so that the said pin or pins 44 deform said membrane 22, in particular its activation zones 24, even more particularly the corresponding domes, during insertion and / or of the transverse displacement of the button 10, this by means of their foot 48.

In the following, the organs involved when the button 10 is activated are detailed.

First of all, said button 10 is articulated with respect to said support 40 to allow said insertion and / or said transverse movement, in particular at least in rotation as already seen.

Furthermore, said device comprises a lug 50 and a guide groove 52 of said lug 50, making it possible to selectively authorize the pushing in or the transverse movement of the button 10 relative to the support 40. The lug 50 is here on the button 10 and the guide groove 52 on the support 40.

More specifically, in the embodiment of Figures 3 to 5, said guide groove 52 is in the form of a T, more particularly visible in Figure 5. The longitudinal branch of the T is straight and / or its transverse branch is slightly curved so as to correspond to the rotation of the button 10.

In the rest position, as illustrated in FIG. 5, the lug 50 is located at the intersection of the transverse and longitudinal branches of the guide groove 52.

If the button 10 is pressed, the lug 50 moves along the longitudinal branch of the guide groove 52. The button 10 cannot therefore be moved transversely, either in one direction or the other because it is blocked by lateral edges of said longitudinal branch. It arrives at the end of travel stop in a position marked A.

In the event of transverse movement of the button 10, in one direction or the other, the lug 50 moves along the transverse branch of the guide groove 52, on one side or another of the intersection branches of said groove. The button 10 cannot therefore be pressed since it is blocked by lower edges of said transverse branch. It arrives at the end of travel stop either in a position marked B or in a position marked C, depending on its direction of actuation.

Said support 40 here has a well 56, said button 10 being located at one end of the well 56 and the contactors 20 being located at the other end.

For better guidance, the assembly formed by the lug 50 and the associated guide groove 52 can be split. Said assemblies are located opposite each other of the well 56. Said guide grooves 52 are each produced at a side 58, said sides 58 being arranged along opposite lateral edges of the well 56 Said lug 50 are arranged in correspondence at opposite lateral sides of said button 10. As a variant, the manual control device may comprise only one of said assemblies.

The movable members also include a movable plate 54, configured to be moved by the button 10 in the support 40, when the button 10 is pressed in. The movable platen 54 is here guided in translation in the well 56. In the event of displacement transverse button 10, the movable plate 54 is fixed, the button 10 can not be pressed. For this, here, said plate 54 comprises bearings 61 of articulation in rotation of the button 10 cooperating with pins 62 provided on the button 10, for example at their lateral side, under the lugs 50. Said pins 44 are movable in guide holes 55, provided in said plate 54.

Said plate 54 is advantageously provided with a protrusion 64, configured to actuate one or more of the first contactors when said plate 54 is moved by said button 10. In other words, in this embodiment of the invention, the actuation of the button 10 by depressing causes a displacement of the plate 54 and its protrusion 64 which depresses the first contactor (s) corresponding to the depressing of the button 10. In other words, in this embodiment, it is the protrusion 64 which activates the contactor corresponding specifically to the pressing of the button 10.

The pins 44 are here arranged on either side of the protrusion 64 of the movable plate 54. A lower face of the button 10 has, facing the head 46 of said pins 44, a flat area used to press on said pins during transverse movement of button 10.

In the embodiment of Figures 6 and following, said button 10 comprises a wheel 70 and a pendulum 72, articulated on said support 40. Said wheel 70 and said pendulum 72 are here both mobile in rotation. Said wheel 70 is configured to be operated by the user. Said balance 72 is configured to be driven by said wheel 70.

The wheel 70 is configured to act directly on the pins 44 corresponding to the first contactors 30. For this, here, said wheel comprises fingers 80 (FIG. 9) configured to press on said pins 44, in particular at the head 46 of said pins 44, when the button 10 is pressed. Said fingers 80 come, for example, from an internal face of the wheel 70. When the wheel 70 is pressed, the device is configured so that the pendulum 72 remains immobile, as will be detailed below.

The pendulum 72 is configured to act on the pins 44 corresponding to the second contactors 32. For this, said pendulum comprises two arms 82 located on either side of an orifice 83 of said pendulum, said orifice 83 cooperating with an axis of articulation 84 (FIG. 7a), carried by a bearing 86 provided on the support 40. Said arms 82 are configured to press on said pins 44, in particular at the level of the head 46 of said pins 44, during the transverse movement of the button 10, c that is to say, during the rotation of the pendulum 72, in one direction or the other. During the transverse movement of the wheel 70, the device is configured so that the pendulum 72 is not depressed, as will be detailed below.

Thus, when the wheel 70 is pressed, only the first contactors 30 are activated, by means of the pins 44 pressed by the fingers 80. When the wheel 70 is moved transversely, only one of the second contactors 32 is activated, this as a function of the direction chosen and by means of the pin 44 associated with the arm 82 of the corresponding pendulum 72. In other words, in this embodiment, it is through the fingers 80 that the contactors 20 corresponding specifically to the depression of the button 10 are activated.

Furthermore, in this embodiment, it can be seen that all of the contactors 20, including the first contactors 30, are actuated by identical moving elements, namely the pins 44.

Said device comprises a pin 74, here on the wheel 72, and a guide groove 76 of said pin 10, here on the pendulum 72, allowing selectively to authorize a drive of said balance 72 by said wheel 70 in the event of transverse movement of the button 10 or to keep said pendulum 72 immobile when the button 10 is pressed.

In this embodiment, as can be better understood with the aid of FIGS. 11 and following, the lug 50 and the guide groove 52 of said lug 50 selectively combine their action with the pin 74 and the guide groove 76 in case of depression or transverse movement of the button 10 relative to the support 40.

The lug 50 is produced at the level of the lower face of the said wheel 70 and the guide groove 52 is located opposite said wheel 70. The fingers 80, the lug 50 and the pin 74 are here substantially in the same plane, the lug 50 being located between the fingers 80, on the one hand, and the pin 74, on the other hand.

The guide groove 52 is formed of a free edge of a flank 77 of material from said support 40. Said free edge has a notch 78 oriented in a direction of depression of the button 10. Said free edge also has wings transverse on either side of said notch 78. Said transverse wings are slightly curved so as to correspond to the rotation of the button 10.

The pin 74 is located, for example, on a lateral face of the thumb wheel 70, located between the bearing 86 of articulation of the pendulum 72 and the material flank 77 carrying the guide groove 52.

In the rest position, the lug 50 is above the notch 78 (Figure 11). The pin 74 is on its side in the high position in the guide groove 76 (Figure 10).

If the button 10 is pressed, the lug 50 moves into the notch 78 (FIG. 13). The button 10 cannot therefore be moved transversely, neither in one direction nor in the other because it is blocked by lateral edges of said notch 78. Simultaneously, the pin 74 moves in the guide groove 76 (FIG. 12 ), without being able to cause the pendulum 72 to pivot since such a pivoting is blocked by the presence of the lug 50 in the notch 78.

In the event of transverse movement of the button 10, in one direction or the other, (FIG. 15), the lug 50 moves along one of the transverse wings of the free edge defining the guide groove 52, from one side or another of the notch 78. The button 10 cannot therefore be depressed because it is blocked by said transverse wing. Simultaneously, the pin 74 drives the balance wheel in rotation by pressing on the lateral edges of the guide groove 76 (FIG. 14).

Said support 40 here has lights 88 on either side of which said button 10, more precisely the dial 70, and the contactors 20 are located. The pins 44 are movable in translation in said slots 88.

For better guidance, as in the embodiment of Figures 3 to 5, the assembly formed by the lug 50 and the associated guide groove 52 may be split. Said assemblies are located opposite either side of the lights 88 receiving the pins 44 corresponding to the first contactors 30. As a variant, the manual control device may comprise only one of said assemblies.

FIGS. 7a to 7f make it possible to understand an example of a method of mounting the manual control device in its embodiment of FIGS. 6 to 15. In FIG. 7a, the pendulum 72 is mounted in the bearing 86 of the support 40. At the FIG. 7b, the thumbwheel 70 is placed on the support 40, the pin 74 then being introduced into the guide groove 76. In FIG. 7c, the pins 44 are introduced into the slots 88, by a lower face of the support, opposite to that carrying the button 10. In FIG. 7d, the membrane 22 is put in place. In FIG. 7e, it is the turn of the printed circuit board 26. FIG. 7f then shows the manual control device by its upper face.

Advantageously, the button 10 comprises an extra thickness of material or groove 11 configured to serve as a support surface for the thumb of the user. It is preferably of limited height in order to facilitate the pressing of the button 10.

By way of purely illustrative examples, the manual control device according to the invention can be used to adjust the parameters of an adaptive speed control system, the transverse movement of the button 10 being used to adjust the desired speed by increasing it. or decrease and pressing the button 10 used to adjust the target safety distance. It can also be used to adjust the sound of a sound broadcasting system, such as a radio, the transverse movement of the button 10 used to adjust the intensity of the sound by making it increase or decrease and the pressing of the button 10 serving to go into silent mode.
