Description

METHOD FOR CLOSING AN OPENING ROOF AND AN OCCULTOR FOR A MOTOR VEHICLE, AND OPENING ROOF MODULE.

The present invention relates to the field of sunroof modules fitted to motor vehicles, more particularly comprising a motorized sunroof and a motorized blind individually guided in sliding on a frame. The invention relates more specifically to the methods of securing the closure of the sunroof vis-à-vis an obstacle potentially placed on its path.

Some motor vehicles are equipped with a sunroof module. According to a specific form, such an opening roof module includes a mounting frame of the sunroof module on the roof of the vehicle, as well as a sunroof and a concealer. The sunroof and the concealer are each motorized mobility between an open position and a closed position, being individually guided in sliding on the frame.

The sunroof and the hatch are in particular guided on the frame in a direction of mobility oriented parallel to a dimension of longitudinal extension of the frame. When the roof module is installed on the vehicle, the direction of mobility is in particular oriented along the longitudinal axis of the vehicle, typically extending between the front and the rear of the vehicle.

Among the known embodiments, the sunroof is arranged in a first panel mounted essentially sliding on the frame. The occluder may be formed of a second panel mounted essentially sliding on the frame, or for example still to be formed of a fabric mounted on a motorized retractor and guided sliding on the frame. The respective engines of the sunroof and the occluder are each placed under the control of a control module.

The implementation of the control module is controlled by one or more controllers activatable by a user, to cause the closing or opening of the sunroof and / or the occulteur. A main control member is notably installed at the driving position of the vehicle, to allow the driver to maneuver the sunroof and / or the occulteur.

It is also known ancillary control members for remotely controlling the implementation of the control module. Such remote control members are for example constituted by an ultrasonic or infrared remote control, or even a pocket terminal (smartphone in English).

There is the problem of securing the maneuvering of the sunroof and / or the concealer vis-à-vis an obstacle placed on their path. Such a problem is typically identified for motorized maneuvers closing the sunroof and / or the occult, due to the potential presence of an obstacle placed in their path along said mobility direction.

The resolution of this problem currently implements at least one sensor participating control members of the motorization of the sunroof. In the event of an obstacle preventing the closing of the sunroof detected by the sensor, the control module interrupts the maneuver when closing the sunroof and / or the concealer, or causes them to return to the open position.

However, it seems appropriate to consolidate such security. Indeed, the sunroof, in particular formed of a generally flat sliding panel, is essentially maneuverable in the open position in the direction of mobility. Prior to the mobility of the sunroof in the direction of mobility, it is common to maneuver along at least one other axis of mobility, such as for example a vertical axis of mobility perpendicular to the extension plane of the roof panel opening.

Maneuvering the sunroof along the vertical axis of mobility allows it to be released by slightly lifting its storage compartment in the closed position on the vehicle. However, as a result of the lifting of the sunroof, gaps are formed between the sunroof and the edges of the window that includes the roof of the vehicle to receive the sunroof module. Such interstices are problematic with regard to passenger safety.

Indeed, such gaps provide passages through which can be introduced an obstacle, such as the hand of an individual present inside the passenger compartment for example. As a result, there is a risk of injury to the individual by pinching between a side edge of the opening and a side edge of the sunroof oriented parallel to the direction of mobility of the sunroof.

Among the possible solutions, arrangements may be provided for masking said interstices.

For example, a flexible flap may oppose the introduction of an obstacle in the passage formed between a lateral edge of the opening and a side edge of the sunroof. However, the effectiveness of such a solution is insufficient and does not respond satisfactorily to the problem. Such dissatisfaction is revealed in particular in the case of the use of a remote control member to control the closing of the sunroof and / or the occulter. Indeed in this case, the user of the remote control member can not remotely perceive the presence or absence of an individual inside the passenger compartment.

For example again, structurally more or less complex protection mechanisms can be exploited. Such protection mechanisms can be maneuverable as a result of activation of the motorization of the sunroof and / or its movement along the frame. However, such mechanisms complicate the architecture of the sunroof module and are expensive, which is to be avoided.

It is also to take into account the structure of the occulteur, and in particular its density capable of obstructing the passage of light.

Indeed, in the case of a high-density concealer, its opening is prohibited simultaneously to the opening of the sunroof when the vehicle is in progress, at the risk of causing its tearing. To overcome this disadvantage, it is known occulters of low density more or less openwork, but their ability to block the passage of light is reduced, which can cause dissatisfaction of the customer.

In this context, the present invention relates to a method of maneuvering in the closed position of a sunroof participating in a sunroof module for a motor vehicle. The invention also relates to a sunroof module adapted to implement the method of the invention, and a motor vehicle equipped with such a sunroof module. The invention falls within the scope of the constraints and difficulties to overcome above mentioned, and aims to propose a solution to prohibit a risk of biessure for an individual present in the room, as a result of a command at the closing of the sunroof.

The method of the present invention is a method of maneuvering from an open position to a closed position, a sunroof and an occuiter that includes a sunroof module for an automobile vehicle.

The sunroof is preferably formed of a first panel essentially movable in sliding in its general plane between its closed position and its open position. The concealer is slidably guided parallel to the sunroof by being for example formed of a second panel or a fabric mounted on a reel.

The sunroof and the hatch are guided on a frame in a direction of common mobility, being individually motorized for their individual maneuvers between their respective positions of opening and closing. As conventionally in respective closed positions, the sunroof and / or the obstruction seal the recess inside the frame. In the respective opening positions of the sunroof and / or the suitor, the recess inside the frame is at least partially clear of the sunroof and / or the occupant.

The respective motorizations of the sunroof and the manufacturer are each controlled by a control module placed under the control of at least one control member activated by a user. The control member generates commands sent to the control module, at least of which a first order relates at least to a maneuver of the sunroof in the closed position by the control module, that is to say a maneuver of the sunroof towards the closed position. In general, such a control member is conventionally generating, as a result of its activation by a user, selective orders for implementing the control module. As a result of the transmission of such commands to the control module, the control module controls the respective motorizations of the sunroof and the obsessor, to provoke separately or jointly the opening and / or closing of the sunroof and / or of I'occuiteur.

Typically, the sunroof and the obstruction each comprise an edge oriented perpendicularly to the direction of mobility and extending parallel to one edge of the frame. The edge of the sunroof and the edge of the speaker are located at a distance from said edge of the frame when they are placed in their respective opening positions. The window formed through the paviiion of the vehicle and receiving the sunroof module is thus at least partly cleared of the presence of the sunroof and / or the occultor placed individually or collectively in the open position.

In this context, the method of the invention is mainly recognizable in that the control module causes a maneuver of the sunroof to its closed position, subject to a criterion. This criterion is particularly a combination of several information received by the control module.

Said criterion is more particularly at least reactive to a reception by the control module of a said first order and to a detection by the control module of a first position reiative between the sunroof and the occluder, according to which the edge The shade is closer to the edge of the frame than the edge of the sunroof.

A maneuver of the sunroof to its closed position is then prohibited if the occulteur is not overflowing from the sunroof towards said edge of the frame. An eventual passage between the sunroof frame is thus masked by the speaker from within the habit, the obstacle preventing a possible individual present in the home to introduce his hand through this passage.

A useful aspect of the invention is in particular the possibility for a user to remotely control the closing of the sunroof, without inducing a risk of injury to an individual present in the habitat, and this even without the user having access to it. a way to check such a presence.

Thus, this criterion can also be at least reiative to the reception by the control module of a said first order generated by a control member specifically consisting of a remote control member. Such a remote control member is likely to be a remote control of proximity, such as an ultrasonic or infrared remote control for example, or to be a pocket terminal operating by radiofrequency wave emission and operating a communication network, such as in particular at least one cellular telephone network.

Said first order is likely to be furthermore an order relating to a maneuver of the hatch towards its closed position together with a maneuver of the sunroof towards its closed position. An alternative option is particularly selectable by the user of the control member, and is particularly useful in the case of the use of a remote control member and the impossibility for the user of a visual control. the condition of the vehicle.

In other words, said first order is likely to be relative only to a maneuver of the sunroof to its closed position, or to be relative to a joint operation of the sunroof and the concealer to their respective positions closure. The first order is likely to raise either an order relating to an isolated maneuver of the sunroof, or an order relating to a joint maneuver of the sunroof and the occulteur.

It will be noted that the generation and transmission to the control module of a said first order relating to an operation of the sunroof alone, does not exclude a potential maneuver of the shield under control of the control module. Indeed, the control module is able to cause a maneuver of the concealer to its closed position, until detection by the control module of the condition of said criterion, according to which the sunroof and the concealer must be placed in said first relative position to allow a maneuver of the sunroof to its closed position.

For example, it is considered a first case that the control module detects a second relative position between the sunroof and the concealer. In said second relative position, the edge of the shade is further away from said edge of the frame than the edge of the sunroof. In this case, the control module causes as a result of a reception of the first order a maneuver only the occulteur to its closed position. Then, under the condition of said first relative position, the control module then causes a maneuver of the sunroof to its closed position.

For example again, it is considered a second case in which the sunroof and the concealer are simultaneously maneuvered to their respective closed positions. More in this second case, the control module detects an obstacle to the operation of the occulteur. The control module then causes a maneuver of the sunroof and the cloak from their current positions to their open positions at the end of the race on the frame.

Preferably in said second case, an alert signal is generated and transmitted by the control module to at least one organ generating a perceptible alert by the man. The generating member of an alert is for example at least one of the lighting devices on the vehicle, the alert perceptible by the man then being formed of a light signal. In the case where the control member is a remote control member, in particular constituted by a pocket terminal, the remote control member may advantageously be used to constitute the generating member of the alert perceptible by the 'man.

In this case, an alert information is transmitted by the control module to the remote control member to communicate the alert to the user of the control device, via a communication network operating in particular at least one network. cell phone. The invention also relates to a sunroof module adapted to implement a method as just described.

The sunroof module of the invention comprises in particular at least one said sunroof and its engine, a so-called occulteur and its engine, a said sunroof guiding frame and the occulter, a said control module, at least a said control member and a relative position detector between the sunroof and the concave according to their direction of common mobility.

Preferably, said at least one control member is specifically a remote control member.

More preferably, the sunroof module comprises an obstacie detector against a maneuver of the occuiter to its closed position. The invention also relates to a motor vehicle equipped with a sunroof module as just described.

Embodiments of the present invention will be described in reciation with the figures of the attached plate, in which: -) Figure 1 is a schematic top view of an embodiment of a roof sunroof compliant with FIG. 2, FIG. 3 and FIG. 4 are diagrammatic representations of the sunroof module represented in FIG. 1, illustrating, in accordance with respective steps, an example of implementation of a method according to the invention. .

The figures and their detailed description expose the invention according to particular modalities and can of course be used to better define the invention, both in its particularities and in its generality, particularly in relation to the general description of the invention which has just been described. to be made.

In the figures, a sunroof module 1 is configured for its instaiiation on the flag 2 of a motor vehicle. The sunroof module 1 comprises a sunroof 3 and a concealer 4, each independently movable between an open position and a closed position. The sunroof 3 and the obstruction 4 are guided on a frame 5 in a direction of common mobility DM, being pieced in superposition relative to each other on the frame 5, as illustrated in FIGS. at 4.

The direction of mobility DM is conventionally oriented in the general plane of the frame 5, parallel to its longitudinal sides 6, 6 'facing each other, along which the sunroof 3 and / or the occuiter 4 are individually guided. When the sunroof module 1 is installed on the roof 2 of the vehicle, the direction of mobility DM is oriented in the longitudinal direction of extension of the vehicle, extending typically between the front and the rear of the vehicle.

Ciassiquement in closed positions, ie sunroof 3 and / or the occuiteur 4 close the evidement of the frame 5. In opening positions of the sunroof 3 and / or the monoculture 4, the recess 7 of the frame 5 is at least partially, if not almost completely, clear of the sunroof 3 and / or the occuiter 4. In the figures, the sunroof 3 and the occuiter 4 are shown in their own opening positions, in which they partially block the recess 7 of the frame 5 or in other words partially release the recess 7 of the frame 5.

Consequently, in opening positions, the sunroof 3 and / or the occuiter 4 can conventionally be placed at respective distances d1, d2 from an edge 8 of the frame 5 oriented transversely to their mobility direction DM, such that illustrated for example. One of the edges 9,10 of the sunroof 3 and the occuiter 4 is then typically identified in the opening positions of the sunroof 3 and / or the occuiter 4, as being oriented parallel and disposed opposite said edge 8 of the frame 7 extending transversely to the mobility direction DM.

In other words, said respective edges 9, 10 of the sunroof 3 and of the occuiter 4 are oriented transversely to their common direction of mobility DM and are arranged at a distance and facing each other on said transverse edge frame 5 in the open positions of the sunroof 3 and / or the occuiter 4. A gap El can be provided between said respective edges 9, 10 of the sunroof 3 and the occuiter 4, depending on their relative position. relative to each other as illustrated.

Furthermore, the sunroof 3 and the concealer 4 are equipped with respective engines 11, 12 for their individual maneuvers between their open and closed positions. Said engines 11, 12 are placed under the control of a control module 13, controlling the maneuvers of the sunroof 3 and the shield 4 between their open and closed positions.

The implementation of the control module 13 is dependent on at least one control member 14 activated by a user. The control member 14 is advantageously a remote control member, which can allow the user to remotely control the opening or closing of the sunroof 3 and / or the occulter 4, in particular without visual perception of the vehicle . The user can generate orders by selective activation of the control member 14. The orders are transmitted to the control module 14, to control the respective implementations of the engines 11, 12 assigned to the sunroof 3 and the occult 4 for their respective maneuvers in open and / or closed positions.

Among the orders, it is in particular considered a first order 15 relating to the maneuver to their closing positions of the sunroof 3 and / or the occulter 4. Such a first order 15 comprises at least one order relating to the closing of the roof opening 3, and preferably also includes an order relating to the closing of the occulter 4.

The implementation of the control module 13 is also placed under the control of a position detector 16 able to detect a said gap El of position between the sunroof 3 and the concealer 4, with respect to the edge 8 of the frame 5. The implementation of the control module 13 is also placed under the control of an obstacle detector 17 against a maneuver of the shield 4 to its closed position.

In FIG. 2, the sunroof 3 and the concealer 4 are in the open position partially closing the recess 7 of the frame 5. The edge 9 of the sunroof 3 is placed closer to the edge 8 of the frame 5 than the edge 4. A first order 15 is transmitted to the control module 13 to cause at least the operation of the sunroof 3 to its closed position.

The position detector 16 also transmits to the control module 13 a first piece of information 18 relating to a first position gap E2 between the edge 9 of the sunroof 3 and the edge 10 of the concealer 4 with respect to the edge 8 of the frame 5. The first information 18 is preferably transmitted to the control module 13 in the case where the first position difference E2 is greater than a first predefined difference threshold.

The control module 13 then generates a first control 19 relating to a maneuver on closing the concealer 4, activating its motorization 12. The concealer 4 is then maneuvered Ml towards its closed position.

In FIG. 3, the current M1 maneuver of the concealer 4 towards its closed position then places its edge 10 closer to the edge 8 of the frame 5 than the edge 9 of the sunroof 3, according to a second difference E3 of relative position. The position detector 16 then transmits to the control module 13 a second piece of information 20 validating an implementation of the motorisation 11 of the sunroof 3 to cause it to move towards its closed position. The transmission of the second piece of information 20 is preferably performed when the second position difference E3 between the hatch 4 and the sunroof 3 reaches a second predefined gap threshold.

The control module 13 then generates a second control 21 relating to a maneuver M2 closing the sunroof 3, activating its engine 11. The occulting 3 and the sunroof 4 are then jointly maneuvered M1, M2 to their closed positions preferably at identical speeds in order to keep the second position difference E3 constant until the occluder 4 is placed in the closed position. As a result of detecting the concealer 4 placed in the closed position, a positional difference between the concealer 4 and the sunroof 3 is no longer taken into account by the position detector 16 and / or by the module control 13, to control the maneuver M2 sunroof 3 to its closed position. The maneuver M2 of the sunroof 3 to its closed position continues until a detection by the control module of a placement of the sunroof 3 in the closed position.

In FIG. 4, it can happen that an obstacle 22 opposes the maneuvering of the shield 4. In this case, the obstacle detector 17 transmits a third piece of information 23 to the control module 13, which then generates third commands 24, 24 '. The third controls 24, 24 'may relate to commands for stopping the respective maneuvers M1, M2 of the sunroof 3 and of the concealer 4 towards their closed positions.

Preferably, the third controls 24, 24 'are relative to maneuvering controls M3, M4 respectively of the sunroof 3 and the shield 4 to their open position. In this case, the sunroof 3 and the occluder 4 are maneuvered M3, M4 until they are placed on the frame 5 at the end of races of their respective open positions.

The control module 13 then generates an alert signal 25 transmitted to at least one generating member of an alert 26 perceptible by the man. In the illustrated example the alert signal 25 is transmitted to the control member 14 remotely, including radio frequencies via the cellular telephone network. The control member 14 then generates a message relating to said alert 26 and perceptible by its user. Such a message is likely to be a message in visual and / or sound form.
