Description

Control device for a sunroof and a blackout blind, and corresponding motor vehicle roof. The field of the invention is that of motor vehicles, and more specifically fully or partially glazed pavilions of such vehicles.

More specifically, the invention relates to the control of a sunroof, that is to say a movable shutter panel of an opening in the roof, and means of occultation of at least a part of the glazed surface of the pavilion (roller blind or awning for example). It is known to equip the glazed pavilions with a sunroof, which can be motorized. It is also known to equip this flag means of occultation of the glass surface, which can also be motorized. The motorization of these two elements, sunroof and obscuration element, is conventionally provided by separate motors, each controlled by a control button, to independently control the movement of the sunroof and that of the occulting element. As a result, certain situations can lead to damage to the concealment element, especially when it is deployed above the opening, while the sunroof panel is open. To avoid this problem, the document FR-2 917 513 proposes a single control button, configured to control both the sunroof panel and the concealment element, by prohibiting undesirable configurations. For this, the control button comprises two coaxial wheels associated respectively with the control of the sunroof and the control of the concealment element. These wheels are each equipped with a lug, cooperating with each other, so that the range of movement of the second wheel is variable depending on the position of the first wheel. This approach therefore makes it possible to effectively prohibit certain undesirable configurations of opening and / or closing of the sunroof and the concealment element. However, the button, formed of two wheels, each having at least one lug, is complex to manufacture and assemble, and therefore relatively expensive. Another example of a complex control knob with coaxial wheels, more particularly dedicated to flags with several moving elements, is described in document EP-1 213 168.

The invention particularly aims to overcome these disadvantages of the prior art. More specifically, an object of the invention is to provide a control device of a sunroof panel and a shade element for glazed roof that is mechanically simple and therefore inexpensive.

The invention also aims, of course, to provide such a control device, which is reliable in time, and easily adjustable, particularly with regard to the initialization of the positions of the sunroof panel and the element occultation. These objectives, as well as others that will appear later, are achieved according to the invention using a device for controlling the movement of a movable shutter panel of an opening in a vehicle roof. automobile, powered by a first motor, and a corresponding concealment element actuated by a second motor. According to the invention, the control device comprises a single button for controlling the movement of said movable panel and said occulting element, which can take a plurality of predetermined positions, and means for generating a set of predetermined electrical signals associated respectively with at each of said positions, a first subset of said electrical signals being associated with said movable panel, and being recognized by said first motor, and a second subset of said electrical signals being associated with said occulting element, and being recognized by said second engine. Thus, according to the invention, it is possible to control the opening and closing of the sunroof panel and the concealment element, simply and efficiently, with the aid of a single button. The unauthorized positions are managed by the distinction of the different signals generated, allocated selectively to one or the other of the two engines. According to a first embodiment, said electrical signals carry binary information. Each binary value then corresponds to one of the positions of the sunroof or the concealment element. In this case, the control device may for example deliver a plurality of binary outputs, each of which may take two states (0 or 1) and each being associated with at least one electrical cable, said electrical cables being connected to said first and / or said second motors, so as to transmit to these latter said binary information. According to a second embodiment, each of said predetermined electrical signals corresponds to an electrical voltage or to a range of electrical voltages. Said control button can in particular be rotatable, and can be moved over a predetermined angular range. In this case, said angular range can be decomposed into a first angular range, comprising at least two intermediate positions associated with the control of said movable panel and a second angular range, comprising at least two intermediate positions associated with the control of said occulting element . In particular, said button can be movable between a minimum position in which the concealment element and the movable panel are in a closed position and a maximum position in which the concealment element and the movable panel are in an open position .

According to an advantageous characteristic, the control device comprises first initialization means enabling the position of said mobile panel to be adjusted with respect to a predetermined position of said button. In particular, said predetermined position of said button may correspond to the closed position of said movable panel.

Similarly, the control device may include second initialization means for adjusting the position of said occluding member with respect to a predetermined position of said button. Said predetermined position of said button may advantageously correspond to the closed position of said occulting element. Said first and / or second initialization means may for example be implemented on receipt of a specific electrical signal, after pressing for a predetermined duration on said button. The invention also relates to the flags of a motor vehicle comprising: - a movable panel between a closed position and at least one open position, - a movable concealment element between a closed position and at least one open position, and - a device for control as described above. Other features and advantages of the invention will emerge more clearly on reading the following description of an illustrative and nonlimiting embodiment, and the appended drawings in which: FIG. 1 illustrates an example of a glazed roof which can be equipped a control device according to the invention; FIGS. 2A to 2J schematically illustrate the respective positions of a concealment element and a sunroof panel, in an exemplary implementation using a 10-position control button; FIG. 3 illustrates an example of electrical wiring of a control device according to the invention, in the case of a four-bit binary coding. Figure 1 therefore shows an example of a glazed roof, known to be incorporating a sliding roof mobile panel, or sunroof by abuse of language, and an occulting element, or occulteur. This pavilion comprises a fixed panel 11, intended to be secured to the frame. This fixed panel is at least partially glazed and has a central portion transparent, or at least able to partially allow the sun's rays. The edges of this fixed panel can be screen printed.

An opening 12 is formed in this fixed panel 11, and can be closed or disengaged by a sliding panel 13, here also totally or essentially glazed. A concealment element 14 is also provided, to allow protection of the occupants against the sun's rays. This occulting element 14 is here an occulting cloth mounted on a winding tube (not shown). It can also be a rigid or partially rigid awning. For purposes of illustration, the movable panel 13 and the concealment element 14 are shown partially open. In practice, according to the embodiment described below, note that this situation does not exist, the blackout blind 14 can be deployed only when the sunroof is closed. By way of an exemplary embodiment, FIGS. 2A to 2J illustrate an example of implementation of the invention, using a rotary knob with ten positions numbered from 0 to 9. The positions 0 to 4 , corresponding to FIGS. 2A to 2E, control the movement of the blackout blind 14, the sunroof panel 13 being closed: FIG. 2A: position 0: the sunroof panel 13 is in the closed position, and the fabric of the blind 14 is fully deployed. As explained below, it is possible to initialize the occulting element in this position, for example by pressing on the central portion 22 of the button 21; FIG. 2B: position 1: the sunroof panel 13 is closed, and the blackout blind 14 is in an intermediate position 1; FIG. 2C: position 2: the sunroof panel 13 is closed, and the blackout blind 14 is in an intermediate position 2; 2D figure: position 3: the sunroof panel 13 is closed, and the blackout blind 14 is in an intermediate position 3; 2E: position 4: the sunroof panel 13 is closed, and the occulting element 14 is open, that is to say folded, or wound. In this position, according to an embodiment of the invention specified below, it is possible to initialize the position of the sunroof in this position by pressing on the central portion 22 of the button 21. FIGS. 2F to 2J control the movement of the sunroof panel 13, the occulting element 14 being in the open position, or folded: FIG. 2F: position 5: the blackout blind 14 is open, and the sunroof is in an intermediate open position 1; FIG. 2G: position 6: the blackout blind 14 is open, and the sunroof is in an intermediate open position 2; FIG. 2H: position 7: the blackout blind 14 is open, and the sunroof is in an intermediate open position 3; FIG. 2I: position 8: the blackout blind 14 is open, and the sunroof is in an intermediate open position 4; FIG. 2J: position 9: the blackout blind 14 is open, and the sunroof 14 is in an entirely open position. It is thus possible, with a single rotary knob, to control the movement of the sunroof panel and the concealment element, by prohibiting the respective undesirable positions. According to a first implementation, the button 21 may output binary values, for example in the form of a digital output, on four bits in parallel in the case of ten positions. According to another approach, this rotary knob can deliver a single analog output, which can take several, in this case 10, distinct voltage values VO to V9. The attached table gives an example of a four-bit on-off binary coding and analog output voltage level coding for such a ten-position button. Example of 10-position button-level coding binary coding on voltage on 4-bit analog on / off output output Open blind / open sunroof 0001 Voltage level VO Open blind / sunroof position 4 0011 Voltage level V1 Open awning / roof opening position 3 0010 Voltage level V2 Blind open / sunroof position 2 0110 Voltage level V3 Blind open / sunroof position 1 0111 Voltage level V4 Blind open / sunroof closed 0101 Voltage level V5 Blind position 3 / sunroof closed 0100 Voltage level V6 Blind position 2 / sunroof closed 1100 Voltage level V7 Blind position 1 / sunroof closed 1101 Voltage level V8 Blind closed / sunroof closed 1110 Voltage level V9 Initialisation blind / sunroof 0000 Voltage level V10 It should be noted that the last line corresponds to a value distinct from the ten positions, respectively 0000 or voltage V10, corresponding to the initialization the position of the occulting element and the sunroof, obtained for example by pressing on the central portion 22 of the button 21. This central portion 21 can be movable in translation along its axis between a rest position and a contact position, the contact for a predetermined duration (for example 4 s) generating the emission of this distinct value. Returning means ensures the return of the central portion 22 in the rest position, in the absence of support. Figure 3 schematically illustrates an example of an electrical wiring of the control system, in the case of a rotary knob using a four-bit binary coding. In this embodiment, the rotary knob 21 has an input 1 connected to ground. of the vehicle and an input 4 receiving an authorization signal from the vehicle when the ignition is on. It also includes four outputs numbered 2, 3, 5 and 6, which are binary outputs all or nothing.

The motor 31 of the sunroof panel and the motor 32 of the roller blind comprise an input 8 connected to the vehicle ground, an input 10 connected to the positive pole of the battery and an input 2 connected to the authorization signal, indicating that the contact is put. Moreover, these two motors 31 and 32 comprise four inputs numbered 5, 9, 3 and 4 respectively connected to the outputs 2, 3, 5 and 6 of the rotary knob 21. Thus, the two motors receive the four-bit binary codes issued on the rotary knob 21, and respectively control the sunroof panel and blind concealment, according to the rules defined by the table presented above.

Other variants of implementation are, of course, depending on the configurations of the motors used and the control buttons. In particular, the button 21 is not necessarily rotatable, but may for example be mobile in translation. Similarly, the position number can be reduced or increased as needed. It is also possible to provide positions in which the blind is partially deployed, while the sunroof is partially or completely open. As indicated above, a specific coding value (for example 0000) or a specific voltage (for example V10) may be assigned to the initialization of the closed positions of the concealer and / or the sunroof.

According to a particular embodiment, the initialization of the occluder can be carried out when the button 21 is in position 0 (FIG. 2A). In this position, pressing on the central portion 22 (also called push) for a period of a few seconds, for example 4 seconds, an initialization signal (for example 0000 or V10) is generated. This causes the occluder to close.

The user maintains the support on the central portion 22 until closing and until the motor lock. The occultor is then initialized. In the same way, a prolonged press of 4 seconds on the central portion 22 when the button 21 is in position 4 (Figure 2D) ensures the initialization of the sunroof. The initialization signal causes the closing of the sunroof, and it is initialized when the user having maintained the support, the sunroof is closed and the motor blocked.
