Description

Control system including control member and related manufacturing method

Technical Field

The present invention relates to a control system of a vehicle according to the first aspect, the system comprising a selection member rotatably movable relative to a surface of the control system.

Background

Such control systems are for example integrated into a trim part of the vehicle, such as an instrument panel, a control panel, a center console arranged between two front or rear rows of seats of the vehicle, a display device or other. The control system allows a user to interact with, for example, a display device to display useful information, such as navigation information, pictograms, etc., to the driver and/or passengers, and/or to control certain functions of the vehicle, such as adjusting the intensity of parameters (e.g., volume, temperature, etc.) within the cab.

FR3104764 A1 describes one such control system comprising a touch surface on which a control member is fixed. The control member comprises a body and a selection part constituted by a ring arranged around the body and rotatably movable with respect to the control part. The control means comprise detection means which interact with the touch surface and thus learn the position of the control means relative to the touch surface.

Disclosure of Invention

The object of the present invention is to further improve such a control system by proposing a control system that is simpler and less costly to manufacture.

Thus reducing the cost of the control system. Furthermore, the protrusions on which the control members are mounted are formed directly from the assembly of the support layer and the decorative and functional layer, without the need to fix the additional attachment to the surface of the control system. The number of components of the control system is reduced, which facilitates manufacturing of the system and reduces costs.

Detailed Description

In fig. 1 to 3, a control system 10 for a vehicle according to a first embodiment of the present invention is shown in top view and cross-sectional view. Such as a motor vehicle or other vehicle.

The control system 10 is integrated, for example, into a trim component of a vehicle, such as an instrument panel, a control panel, a center console disposed between two front or rear rows of seats of the vehicle, a display device, or others.

In the lower part of the description, the adjective "external" means a surface intended to be oriented towards the interior of the vehicle cabin. Conversely, the adjective "inner" means the surface opposite the outer surface.

The control system 10 includes a support layer 12, a decorative and functional layer 14 in contact with the support layer 12, at least one first detection sensor 16, and a control member 18.

The support layer 12 is preferably a layer of plastic material, preferably a molded layer, as will be described below. For example, the plastic material is polypropylene (PP), polyvinyl chloride (PVC) or Acrylonitrile Butadiene Styrene (ABS). The support layer 12 includes an outer surface 20 and an inner surface opposite the outer surface 20.

The decorative and functional layer 14 includes an inner surface 22 and an outer surface 24 opposite the inner surface. In the embodiment shown in fig. 1-3, the inner surface 22 of the decorative and functional layer 14 is in contact with the outer surface 20 of the support layer 12. By "contact" is meant that the decorative and functional layer 14 is in direct contact with the support layer 12 without the need for an intermediate layer or intermediate component between the decorative and functional layer 1 and the support layer 12. The outer surface 24 of the decorative and functional layer 14 thus forms the outer surface of the control system 10 that is visible to a user inside the vehicle cabin.

According to one variant of implementation, the outer surface 24 of the decorative and functional layer 14 is in contact with the inner surface of the support layer 12. The outer surface 20 of the support layer 12 then forms the outer surface of the control system 10 that is visible to a user inside the vehicle cabin.

The decorative and functional layer 14 preferably includes a film 26 and at least one decorative member (not shown) secured to an outer surface of the film 26. For example, the decorative element is a pattern and/or pictogram and/or texture, and/or text or the like. For example, the decorative member is printed on the film 26 by a printing device.

It is further preferred that the decorative and functional layer 14 include one or more electronic components secured to the film 26. The one or more electronic components are, for example, resistors, microcircuits, light emitting diodes. It is further preferred that the decorative and functional layer 14 comprises a plurality of conductive tracks interconnecting the electronic components. The conductive tracks are printed on the film 26 using ink, for example by means of a printing device.

The film 26 is, for example, a layer of plastic material, such as Polycarbonate (PC) or polymethyl methacrylate (PMMA). In particular, the membrane 26 is compatible with high pressure molding processes. The thickness of the membrane 26 is for example between 125 μm and 1mm, preferably between 250 μm and 375 μm.

The decorative and functional layer 14 and the support layer 12 form the assembly 11. Preferably, the decorative and functional layer 14 and the support layer 12 form a two-layer composite, that is to say the component 11 comprises only the decorative and functional layer 14 and the support layer 12.

According to the invention, the assembly 11 defines at least one first region 28 and at least one second region 30 forming a projection 32 projecting along the first axis a with respect to the first region 28. The projection 32 is intended to project towards the inside of the cab. The first region 28 is, for example, substantially planar and extends around at least a portion of the second region 30. The decorative and functional layer 14 and the support layer 12 extend continuously between the first region 28 and the second region 30, that is to say the decorative and functional layer 14 covers the support layer 12 in both the first region 28 and the second region 30. In other words, the support layer 12 and the decorative and functional layer 14 each include a first region 34, 36, which is preferably substantially planar, and a second region 38, 40, which each protrudes relative to the first region 34, 36. In other words, the first region 34 and the second region 38 of the support layer 12 are made of the same material. The first region 36 and the second region 40 of the decorative and functional layer 14 are the same material.

The protrusion 32 preferably defines a substantially circular outer side surface 42. For example, the protrusion 32 forms a crown of the axis a or a truncated cone defining a hollowed out central area 44. As a variant, the protrusion 32 is solid.

The first detection sensor 16 is located at least partially in the second region 30 where the protrusion 32 is formed. The first detection sensor 16 is, for example, a capacitive sensor. The first sensor 16 then comprises a plurality of electrodes 46 arranged in the second region 30, for example about the first axis a. Preferably, the electrodes 46 are each disposed about a first axis a. Advantageously, the electrodes 46 are uniformly spaced around the first axis a, that is to say the angular distance around the first axis a of adjacent two electrodes 46 is constant.

According to a specific embodiment, the first detection sensor 16 is a self-capacitance detection sensor (english "self-capacitance"). The detection sensor 16 includes, for example, two to thirty-six, e.g., eighteen, electrodes 46, each distributed about the first axis a of the protrusion 32.

Preferably, each electrode 46 is located between the membrane 26 of the decorative and functional layer 14 and the support layer 12. Specifically, each electrode 46 preferably includes an inner surface oriented toward the first axis a, in contact with the support layer 12, and an outer surface opposite the inner surface, in contact with the membrane 26.

Advantageously, the electrode 46 is printed on the membrane 26.

The control member 18 is mounted around the protrusion 32. The control member 18 comprises a selection part 48, which is rotatably movable along the rotation axis R with respect to the projection 32, and a guiding part 50, which is preferably fixed on the projection 32.

The selection member 48 is rotatably movable along the axis R with respect to the guide member 50. The selection member 48 is rotatably movable between at least two selection positions. Preferably, the selection member 48 is rotatably movable between a selection position, the number of which is the same as the number of electrodes 46 of the first detection sensor 16. The rotation axis R preferably substantially coincides with the first axis a. In the example shown, the rotation axis R is substantially perpendicular to the first region 28.

Advantageously, the selection member 48 defines internally a through hole 52 which exposes the assembly 11 and, in particular, in the embodiment shown, the decorative and functional layer 14. According to a specific embodiment (not shown), the control system 10 comprises a display device (not shown), such as a screen, arranged inside the through hole 52. The display device is secured, for example, to the decorative and functional layer 14, for example, to the outer surface 24 of the decorative and functional layer 14. As a variant, the display device is fixed on the lower surface of the membrane 26 and at least a portion of the membrane 26 facing the display device along the rotation axis R is translucent or transparent to allow the user to see the display device through said portion of the membrane 26.

According to a particular embodiment, the exterior side surface 54 of the selection member 48 is irregular, such as being striped with a plurality of ribs, each rib extending generally in a direction substantially parallel to the axis of rotation R, to facilitate grasping of the selection member 48 by a user.

Alternatively or additionally, the selection member 48 forms a grooved roller to define a plurality of stable selection positions. The control member 18 then forms a haptic device. When the user rotates the selection member 48, he must apply a predetermined rotational force to switch from one stable selection position to another stable selection position. This allows the user to know precisely the angular distance that the selection member 48 passes and to tactilely perceive the switch between the different selection positions.

In addition, the rotational movement of the selection member 48 causes, for example, a click to be heard by the associated user when switching from one stable selection position to another.

According to the invention, the control member 18 comprises at least one detection means 56, preferably a single detection means 56, which is rotatably connected to the selection means 48. In the example shown, the detection component 56 is, for example, an electrical conductor. The selection member 48 is then preferably non-electrically conductive, that is to say made of an electrically insulating material such as a plastic material.

The detection component 56 is configured to interact with the first detection sensor 16 at each selected location. The first detection sensor 16 then determines the selection position at which the selection member 48 is located.

In embodiments where the first detection sensor 16 is a self-capacitance detection sensor, at each selected location, the detection member faces one of the corresponding electrodes 46 of the first detection sensor 16 substantially along a radial direction that is substantially parallel to the first axis a.

In each selected position, the detection member 56 is configured to change the capacitance of the electrode 46 facing it in the radial direction. Specifically, the detection member 56 is configured to increase the capacitance of the corresponding electrode 46, which is measured between the electrode 46 and ground, when it faces the electrode 46. Thus, by detecting an increase in the capacitance of the electrode 46, the first detection sensor 16 is then configured to determine the relative position of the detection member 56 with respect to the protrusion 32 and thereby determine the position at which the detection member 56 is located.

The geometry and dimensions of the detection member 56 are selected such that the detection member 56 is adapted to change the capacitance of the electrode 46. For example, the detecting member 56 has a parallelepiped shape or a cylindrical shape. Preferably, the detection member 56 protrudes an angular distance between 5 ° and 25 °.

Preferably, at each selected location, the detection member 56 extends away from the corresponding electrode 46 in a radial direction. The detection member 56 is located outside the electrode 46 at all selected locations. For example, the detection member 56 is in contact with the decorative and functional layer 14, and more specifically with the outer surface 24 of the decorative and functional layer 14, at all selected locations.

As a variant, the detection means 56 are distant from the decorative and functional layer 14 in the radial direction. For example, the detection member 56 is positioned less than 3mm from the decorative and functional layer 14.

In the first embodiment shown in fig. 3, the guide member 50 is fixed on the first region 28 and/or the second region 30, and in particular against the base 58 of the projection 32, that is to say at the transition between the first region 28 and the second region 30. For example, the guide member 50 is adhered to the first region 28 and/or the second region 30. As a variant, the guide member 50 is clamped on the projection 32. As a modification, the guide member 50 is screwed on the projection 32. The guide member 50 is disposed externally around the protrusion 32. For example, the guide member 50 is a ring. The guide member 50 defines, for example, an annular groove 60 that mates with the selection member 48, and more specifically with the lower end of the selection member 48. The guide member 50 is fixed relative to the selection member 48. The selection member 48 is rotatably movable about the rotation axis R with respect to the guide member 50.

The operation of the control system 10 will be described below.

For example, the control system 10 according to the present invention is associated with a temperature display device of the cab and allows control of a set temperature.

The user rotates the selection member 48 rightward or leftward around the protrusion 32 as desired to raise or lower the set temperature value. For example, by turning the selection member 48 to the right, it is possible to raise the set temperature. Conversely, by rotating the selection member 48 to the left, it is possible to lower the set temperature. Rotation of the selection member 48 rotates the detection member 56. The first detection sensor 16 is then adapted to determine the angular position of the detection member 56 at all selected positions. The information about the change in position of the detection means 56 is then converted into a command, in this case a user desires to set the temperature up or down.

In embodiments where the first detection sensor 16 is a self-capacitance detection sensor, at each selected location, the detection component 56 increases the capacitance of the electrode 46 facing the detection component 56, as measured between the electrode 46 and ground. The first detection sensor 16 detects the increase and determines the selection position where the selection member 48 is located.

A method of manufacturing the control system 10 as described above will be described below.

First, the decorative and functional layer 14 is prepared. At least one decorative member is printed, for example by printing, on the first side of the film 26. One or more electronic components are secured to a second surface of the film 26 opposite the first surface. For example, a plurality of conductive tracks connecting electronic components to each other are printed with conductive ink. Specifically, in this step, the electrode 46 of the first detection sensor 16 is fixed or printed on the second surface.

The decorative and functional layer 14 is then placed in the molding cavity of the mold. The mold cavity defines a mold representing a three-dimensional negative of the exterior surface of the control system 10, and in particular the first region 28 and the second region 30. Specifically, the first surface of the decorative and functional layer 14 is oriented toward the interior of the mold cavity. The decorative and functional layer 14 is placed in the mold such that the electrode 46 is at the protrusion 32 after molding is complete.

The mold is closed and then material is injected into the interior of the mold to form the support layer 12. The material fills the mold cavity and contacts the decorative and functional layer 14. The decorative and functional layer 14 is deformed and takes the shape of a stamp. The decorative and functional layer 14 is attached to the support layer 12. Specifically, during this step, first region 28 and second region 30 are formed, which form protrusions 32.

The assembly of decorative and functional layer 14 and support layer 12 is released from the mold. The guide member 50 is then secured to the projection 32 by, for example, adhesive, snap fit or tightening. The selection member 48 is then mounted around the protrusion 32 so as to be rotationally movable about the rotation axis R with respect to the protrusion 32 and the guide member 50.

A second embodiment will now be described with reference to fig. 4. This embodiment is described by the differences from the first embodiment.

In this embodiment, the guide member 48 comprises two rings 62 secured to the projection 32, and in particular to the outer side surface 42 of the projection 32. For example, each ring 62 is externally adhered around the protrusion 32. As a variant, each ring 62 is clamped on the protrusion 32.

For example, the selection member 48 internally defines two annular grooves 64 spaced from each other along the rotation axis R, and each cooperates with one of the rings 62. Each ring 62 is connected to a protrusion 32. The selection member 48 is rotatably movable about the rotation axis R with respect to each of the two rings 62.

The manufacturing method is similar to that of the first embodiment.

The third embodiment and the fourth embodiment will now be described with reference to fig. 5 and 6, respectively. These embodiments are described by differences from the first and second embodiments, respectively.

In each of these embodiments, the control system 10 includes a second detection sensor 66 that is at least partially located in the second region 30. In the illustrated example, the second detection sensor 66 is a capacitive sensor.

The second detection sensor 66 comprises, for example, a plurality of electrodes 68 disposed in the second region 30 about the first axis a. The electrode 68 of the second detection sensor 66 is disposed along the rotation axis R away from the electrode 46 of the first detection sensor 16. Preferably, the electrode 68 of the second detection sensor 66 is located below the electrode 46 of the first detection sensor 16 along the rotation axis R, that is to say closer to the base 58 and the first region 28 of the protrusion 32 than the electrode 46 of the first detection sensor 16. Preferably, the electrodes 68 are each disposed about a first axis a. Advantageously, the electrodes 68 are uniformly spaced about the first axis a, that is to say the angular distance between adjacent two electrodes 68 is constant about the first axis a.

According to one specific embodiment, the second detection sensor 66 is a self-capacitance detection sensor (in english "self-capacitance"). The second detection sensor 66 comprises, for example, 2 to 36, for example, 18 electrodes 68, each distributed about the first axis a. The second detection sensor 66 includes the same number of electrodes 68 as the first detection sensor 16. Each electrode 68 of the second detection sensor 66 is arranged side by side with the electrode 46 of the corresponding first detection sensor 16 in a direction substantially parallel to the rotation axis R.

Preferably, each electrode 68 is disposed on an inner surface of the membrane 26. Each electrode 68 is thus disposed between the membrane 26 and the support layer 12. Specifically, each electrode 68 preferably includes an inner surface oriented toward the first axis a, in contact with the support layer 12, and an outer surface opposite the inner surface, in contact with the membrane 26 and specifically in contact with the inner surface of the membrane 26.

As a variant, the second detection sensor 66 comprises a single electrode 68 extending around the first axis a of the protrusion 32. The electrode 68 is, for example, annular. The electrode 68 of the second detection sensor 66 is disposed along the rotation axis R away from the electrode 46 of the first detection sensor 16. Preferably, the electrode 68 of the second detection sensor 66 is located below the electrode 46 of the first detection sensor 16 along the rotation axis R, that is to say closer to the base 58 and the first region 28 of the protrusion 32 than the electrode 46 of the first detection sensor 16.

In addition to being rotationally movable about the axis of rotation R, the selection member 48 is rotationally movable relative to the projection 32 along the axis of rotation R between one of the selection positions and the verification position. The first detection component 56 is configured to interact with the second detection sensor 66 at least in the verification position. In the verification position, the detection member 56 protrudes facing one of the electrodes 68 of the second sensor 66 or facing a single electrode. The detection member 56 is remote from the electrode 68 of the second detection sensor 66 along the first axis a, for example, in the verification position. In each selected position, the detection member 56 is distanced from the electrode 68 of the second detection sensor 66 both along the rotation axis R and in the radial direction.

Upon switching from the selection position to the verification position, the detection member 56 moves translationally along the rotation axis R towards the base 58 of the projection 32, i.e. towards the first region 28.

For example, at each selected location, the detection component 56 does not interact with the second detection sensor 66. The detection component 56 interacts with the second detection sensor 66, i.e. with the electrode 68, only in the verification position. As a variant, at each selected position, the detection means 56 presents a first interaction with the electrode 68 of the second detection sensor 66. In the verification position, the detection component 56 has a second interaction with the electrode 68 of the second detection sensor 66, which is different from the first detection. Thus, verification of the user selection is detected by interaction between the verification detection means 56 and the electrode 68 of the second detection sensor 66. For example, in the illustrated example, movement of the detection member 56 from the select position to the verify position may cause a change in the capacitance of the electrode 68 of the second detection sensor 66, specifically an increase in the capacitance of the electrode 68 measured between the electrode 68 and ground. The second detection sensor 66 is configured to detect such a change and convert it into a user-selected authentication command.

Advantageously, the control system 10 comprises a resetting device 70 of the selection member 48 adapted to move the selection member 48 from the verification position to the selection position. Thus, when the user no longer applies pressure to the selection member 48 along the rotational axis R, the selection member returns to the selected position. For example, the reset means 70 comprises a spring.

The operation of the control system 10 will be described below.

Once the selection member 48 is in the user selected selection position, the user verifies his selection by applying pressure to the selection member 48 to move it toward the first region 28. The selection member 48 is then moved from the selection position to the verification position. The detection component 56 interacts with an electrode 68 of the second detection sensor 66. Information about the change in position of the detection member 56 relative to the electrode 68 of the second detection sensor 66 is then converted into a command, in this case by rotating the selection member 48 to verify the selection made.

The user releases the selection element 48 which is returned to the selection position by means of the resetting means 70 of the selection element 48.

In preparing the decorative and functional layer 14, the method of manufacturing the control system 10 includes securing or printing the electrode 68 of the second detection sensor 66 onto the second surface of the film 26 prior to inserting the decorative and functional layer 14 into the mold cavity. Like the electrode 46 of the first detection sensor 16, the electrode 68 of the second detection sensor 66 is arranged such that it extends into the second region 30 at the die outlet.

As a variant, for all the embodiments presented, the first detection sensor 16 and/or the second detection sensor 66 are mutual capacitive (english "mutual capacitance") detection sensors. Movement of the selection member 46 between the selection positions reduces the mutual coupling between the two electrodes 46, 68 of the detection sensor 16, 66, resulting in a decrease of the capacitance measured at one of the electrodes. The first detection sensor 16 is configured to detect this capacitance drop and determine the selection position at which the selection member 48 is located. The second detection sensor 66 is configured to detect such a capacitance drop and convert it into a user-selected authentication command.

As a variant, for all the embodiments presented, the first detection sensor 16 and/or the second detection sensor 66 are resistive or infrared sensors. The selection means 56 are then adapted to interact with the corresponding detection sensor.

Thus, the control system 10 according to the present invention is particularly advantageous because no touch surface underneath the control member 18 is required, because the detection means 56 interacts with the first detection sensor 16 located in the second area 30. Thus reducing the cost of the control system 10. Furthermore, the protrusions 32 on which the control members 18 are mounted are formed directly from the support layer 12 and the decorative and functional layer 14 without the need to secure additional attachments to the surface of the control system 10. The number of components of the control system 10 is reduced, which facilitates manufacturing and reduces costs of the system 10.
