    [0001] 1 OPENING SYSTEM FOR VEHICLE. The present invention relates to an opening system for a vehicle, in particular for a motor vehicle.
    [0002] More specifically, the invention relates to a sash system for a vehicle comprising: - a frame having an opening; - An opening movable relative to the frame between a closed position in which it closes the opening of said frame and an open position in which it releases the opening of said frame; a locking device comprising: a ferromagnetic element provided on one of the frame and the opening; * A permanent magnet provided on the other of the frame and the opening and magnetically coupled to the ferromagnetic element when the door is in the closed position to apply a closing force; an electromagnet magnetically coupled to one of the ferromagnetic element and the permanent magnet; a control unit comprising a control module electrically coupled to the electromagnet and adapted to control the electromagnet after receiving a control command. US8215684 discloses an opening system of this type implemented at a storage compartment located in the passenger compartment of a motor vehicle and comprising a housing, forming a frame, and a pivoting closure flap by relative to the housing and forming an opening. In this document, when the closure flap is in the closed position relative to the compartment of the storage compartment, the actuation of a control button causes the control, for a predetermined period, of the electromagnet magnetically coupled to the ferromagnetic element 30 so as to break the magnetic cooperation between the ferromagnetic element provided on the housing of the storage compartment and the magnets provided on the closure flap. The flap can then be moved to a position in which it releases the opening of the housing, for example under the effect of an opening action performed by a vehicle occupant or under the effect of gravity. When the occupant of the vehicle wishes to close the storage compartment, it acts directly on the flap to bring it back to the closed position of the housing. The electromagnet is no longer controlled, the shutter is then held in the closed position of the housing by the closing force generated by the magnetic cooperation between the ferromagnetic element of the housing and the magnets on the flap. In the system disclosed in US8215684, nothing is provided for detecting such closing action of the storage compartment performed by a vehicle occupant. The detection of this information, and in particular the arrival of the shutter in the closed position of the housing, may be particularly useful, for example to control the extinction of a lighting device of the storage compartment or to activate a refrigeration device in the storage compartment. More generally, the detection of the arrival of an opening in the closed position of a frame, may be particularly useful for the control of equipment whose operation is conditioned by this information.
    [0003] In the state of the art, there are many devices for detecting the arrival of an opening in the closed position of a frame, these devices using sensors, such as mechanical switches, optical sensors or Hall effect sensors.
    [0004] However, the implementation of such a sensor device in a sash system represents a cost and is not without posing a number of problems in terms of physical integration with the sash system, the sensor device having a certain size and space available within the sash system that can be limited, the limited life of the sensor device that may need to be replaced, or complexity of wiring. The present invention aims to overcome all or part of these disadvantages by providing a sash system in which the arrival of 3025157 3 the opening in the closed position of the frame can be detected without resorting to a sensor device . Thus, the present invention proposes for this purpose an opening system of the aforementioned type, in which the control unit further comprises a detection module which, in the absence of a command instruction received by the control module. , is activated to detect, from the electromagnet, a signal representative of the arrival of the opening in the closed position and to generate information indicating that the opening is in the closed position.
    [0005] Thanks to these provisions, the opening system for a vehicle according to the invention is capable of detecting an arrival of the opening in the closed position of the frame, and of generating information indicating this arrival, without requiring a sensor device, using a signal directly from the electromagnet and characteristic of the arrival of the opening in the closed position of the frame. Thus, the opening system according to the invention has many advantages, particularly in terms of ease of integration, life, reliability or costs. Such an opening system according to the invention can find many applications within a motor vehicle. In particular, such an opening system can be integrated with a storage compartment system, inside or outside the vehicle cabin, a fuel filler system, a bonnet system, a sunroof system or other.
    [0006] In a preferred embodiment of the present invention, the detection module is adapted to receive a current induced in the electromagnet by the magnetic field variation caused by the variation of position between the ferromagnetic element and the permanent magnet when the opening is moved between the open position and the closed position, and the detection module detects a signal representative of the arrival of the opening in the closed position and generates information indicating that the opening is in closing position when said induced current reaches a predetermined detection threshold.
    [0007] When the door is moved relative to the frame, the distance between the ferromagnetic element associated with one of the opening and the frame and the magnet associated with the other of the opening and the frame varies. When the opening is close to the closing position of the frame, the variation of position of the opening relative to the frame, and therefore of the ferromagnetic element relative to the magnet, causes a variation of the magnetic field existing between these two elements. Such a magnetic field variation results in the generation of an induced current in the electromagnet associated with one or the other of the ferromagnetic element and the magnet.
    [0008] In the vehicle opening system according to this embodiment, an induced current threshold, characteristic of the arrival of the opening in the closed position, and in this case characteristic of the contacting of the element. ferromagnetic and magnet, is defined taking into account the physical characteristics of the electromagnet, the ferromagnetic element and the magnet. When the detection module of the control unit is activated, said detection module monitors the current induced in the electromagnet and determines that the opening has arrived in the closed position of the opening when the current induced in the electromagnet exceeds this characteristic induced current threshold. In preferred embodiments of the invention, one or more of the following provisions may be used: the opening system further comprises a switching element electrically connected to the electromagnet and the detection module and adapted to adopt an open state, wherein the electromagnet is electrically isolated from the detection module, following receipt of a control command by the control module, and to adopt a passing state. wherein the electromagnet is electrically connected to the sensor module in the absence of a control command received by the control module; the control module comprises a detection control port adapted to send a detection control signal and the detection module comprises a reception port of the induced current, the switching element is electrically connected to the control port of detection, the switching element is adapted to adopt the open state as long as the detection control signal sent on the detection control port is below a predetermined control threshold, and to adopt the on state when the detection control signal sent on the detection control port exceeds said predetermined control threshold, and the control module sends on the detection control port a detection control signal exceeding the predetermined control threshold in the absence command instruction received by the control module; the switching element comprises an NPN transistor having a base, a collector and an emitter, said base being connected to the control port, said collector being connected to the electromagnet and said emitter being connected to the detection port; the electromagnet is magnetically coupled to the permanent magnet and, after receiving an opening command, the control module electrically supplies the electromagnet so as to demagnetize the permanent magnet so as to cancel the force of closing applied on the opening.
    [0009] With these provisions, the electrical energy required to allow the clearance of the opening of the frame is limited and depends essentially on the power of the magnet implemented in the opening system. the electromagnet is magnetically coupled to the ferromagnetic element and, following receipt of an opening instruction, the control module electrically supplies the electromagnet to polarize the ferromagnetic element so that a force opening, opposite and greater than the closing force, is applied to the opening. Thanks to these arrangements, the opening system according to the invention provides assistance in moving the door to the open position following receipt of an opening instruction 30 by the control module. - Following receipt of an opening command, the control module electrically feeds the electromagnet for a predetermined time; - the opening system further comprises an opening control button operable by a vehicle occupant and electrically connected to the control module so that the opening command is sent to said control module following actuation of the opening control button 5 by an occupant of the vehicle; - Following the receipt of a lock instruction, the control module electrically feeds the electromagnet so as to strengthen the closing force applied to the opening. Thanks to these arrangements, it is possible in particular situations, for example in the event of collision of the vehicle against an obstacle, to reinforce the closing force maintaining the opening in the closed position relative to the frame in order to limit the risk of unwanted opening of the opening system under these particular conditions; the opening system further comprises an event detection device adapted to detect an event and electrically connected to the control module so that the locking instruction is sent to said control module following the detection of the event. an event by the event detection device; the event detection device comprises a collision sensor, a rain sensor, a brightness sensor and / or a presence sensor. Furthermore, the present invention also relates to a method for detecting the arrival of an opening leaf in the closed position of a frame in a sash system as defined above, comprising the following successive steps: receiving a command command from the control unit of the control unit; - in the absence of control command received by the control module, activation of the detection module; 30 - detection, from the electromagnet, of a signal representative of the arrival of the opening in the closed position; - Generating information indicating that the leaf is in the closed position.
    [0010] According to an advantageous arrangement of the detection method according to the invention, the step of detecting, from the electromagnet, a signal representative of the arrival of the opening in the closed position comprises the sub-components. following steps: 5 - reception in the detection module of a current induced in the electromagnet by the variation of magnetic field caused by the variation of position between the ferromagnetic element and the magnet when the opening is moved between the position opening and closing position; comparing the induced current with a predetermined detection threshold; - Detecting a signal representative of the arrival of the opening in the closed position when the induced current reaches the predetermined detection threshold; - Generating information indicating that the opening is in the closed position. Advantageously, the activation step of the detection module resides in the switching action of a switching element electrically connected to the electromagnet and to the detection module, from an open state, in which the electromagnet is electrically isolated. from the detection module, to an on state, in which the electromagnet is electrically connected to the detection module. Other features and advantages of the invention will become apparent from the following description of one of its embodiments, given by way of non-limiting example, with reference to the accompanying drawings.
    [0011] In the drawings: FIG. 1 is a schematic view of a vehicle passenger compartment equipped with a sash system according to the invention applied to a storage compartment; - Figure 2 is a schematic perspective view of a sash system according to the invention applied to a storage compartment interior to a vehicle interior; - Figure 3 is a side view of the opening system of Figure 2 on which the opening is in the closed position of the frame; - Figure 3a shows a detail of Figure 3 to illustrate a portion of the opening of the locking device in the closed position relative to the frame; - Figure 4 is a side view of the opening system of Figure 2 5 on which the opening is in the open position of the frame; - Figure 5 is a schematic view to illustrate an example of a control circuit for the control unit of the opening system according to the invention; FIG. 6 is a flowchart for illustrating the operation of the sash system according to the invention. In the different figures, the same references designate identical or similar elements. In Figure 1, there is shown a motor vehicle cabin 15 equipped with a storage compartment implementing a sash system 1 according to an exemplary embodiment of the invention. Thus, and as shown in Figures 1 to 2, the storage compartment 1 comprises a frame 2 having an opening O and belonging to a housing 20 defining an interior storage space of the storage compartment 1. The storage compartment 1 comprises in addition an opening 3 mobile relative to the frame 2 between a closed position, illustrated in Figure 3, wherein the opening 3 closes the opening O of the frame 2 and prohibits access to the interior storage space E , and an open position, illustrated in Figures 2 and 4, wherein the opening 3 releases the opening O of the frame 2 and allows access to the compartment interior storage space 1. In the embodiment shown in Figures 1 to 4, the opening 3 is movable relative to the frame 2 by pivoting about a pivot axis X. However, the present invention also applies to any other motion kinematics of an opening pa r compared to a frame, such as mobility in translation, mobility combining rotation and translation or other.
    [0012] 3 0 2 5 1 5 7 9 The storage compartment 1 further comprises a locking device 4 for retaining the opening 3 in the closed position relative to the frame 2 and release the opening 3 so that it can be moved to an opening position of the frame 2 upon receipt of an opening command. In the embodiment illustrated in the figures, the locking device 4 comprises a ferromagnetic element 5 provided on the opening 3, a permanent magnet 6 provided on the frame 2 and an electromagnet 7 provided on the frame 2 and magnetically coupled to the frame. permanent magnet 6.
    [0013] The permanent magnet 6 provided on the frame 2 and the ferromagnetic element 5 provided on the opening 3 are magnetically coupled, that is to say cooperate by magnetic coupling, when the opening 3 is in the closed position of the frame 2 so to generate a closing force maintaining the opening 3 in the closed position of the frame 2.
    [0014] Furthermore, the blocking device 4 comprises a control unit 8. As seen in FIG. 5, the control unit 8 comprises a control module 9 electrically coupled to the electromagnet 7 and adapted to control the electromagnet 7. following receipt of a command instruction.
    [0015] Such a command instruction sent to the control module 9 may be an opening command issued following the actuation by an occupant of the vehicle of an opening control button 12 arranged in the passenger compartment as visible for example. In the embodiment shown in the figures, the electromagnet 25, comprising a cylindrical core 70 and a coil 71 surrounding the core 70, is associated magnetically with the permanent magnet 6. In this case, following the receipt of an opening command, issued following the operation of the opening control button 12, the control module 9 supplies the electromagnet 7, preferably for a predetermined period of time, so as to demagnetize the permanent magnet 6 so as to cancel the closing force applied to the opening 3. During this predetermined time, the opening 3 is no longer retained in the closed position of the frame by the locking device 4 and can be moved to an opening position of the frame 2, autonomously, for example under the effect of gravity or under the effect of the expansion of an elastic element, such as a spring, which is compressed when the opening 3 is in the closed position of the frame 2, or in a manner assisted by an occupant of the vehicle, the latter acting directly on the door 3, for example by inserting his fingers in a recess 30 provided for this purpose in the opening 3. Alternatively, and without departing from the scope of the present invention, the electromagnet 7 may also be magnetically coupled to the ferromagnetic element 5. In this case, it is possible to advantageously provide that, following the reception of an opening command, issued consecutively with the actuation of the opening control button 12, the control module 9 supplies the electromagnet 7, preferably for a predetermined duration, for polarize the element 5, so that an opening force, opposite and greater than the closing force, is applied to the opening 3. More precisely, in such an embodiment, the control module 9 supplies the electromagnet 7 in current so that the electromagnet generates a magnetic field polarizing the ferromagnetic element 5 in the same polarity as the contact surface of the permanent element 6. Thus, the ferromagnetic element 5 and the permanent magnet With the same polarity, north or south, a magnetic repulsion force is created between these two elements. The ferromagnetic element 5, the permanent magnet 6, the electromagnet 7 and the current with which the control module 9 supplies the electromagnet 7 are advantageously chosen so that this repulsive force constitutes an opposite opening force. and greater than the closing force. Furthermore, the control module 9 can also electrically power the electromagnet 7 so as to reinforce the closing force applied on the sash, following the receipt of a locking instruction. Thus, another control command sent to the control module 9 may be a lock command issued following the detection of an event by an event detection device 13 provided in the vehicle and electrically connected. to the control module 9. In the exemplary embodiment of the invention illustrated in the figures, the sash system is part of a storage compartment 1 internal to the passenger compartment of the vehicle. In this exemplary application of the invention, the event detection device may be a collision sensor adapted to detect a collision of the vehicle that it equips with an obstacle. Indeed, in case of collision, the shock to the vehicle is likely to cause an unexpected opening of the opening 3 retained in the closed position by the magnetic cooperation of the ferromagnetic element 5 and the magnet 6. Also, 10 in such a situation, it may be necessary to apply to the opening 3 a reinforced closing force to prevent unexpected opening of the opening 3. Alternatively, and depending on the vehicle system at the level of which is implemented the opening system according to the invention, the event detection device may also be a rain sensor, a brightness sensor or a presence sensor. The operation and the control of the electromagnet 7 by the control module 9 of the control unit 8 following the reception of a command command, whether it be an opening command or a locking command, are known. of US8215684 cited above and will not be described here in more detail. According to the invention, the control unit 8 further comprises a detection module 10 provided, when activated, to be able to detect a signal, coming from the electromagnet 7 and representative of the arrival of the opening 3 in the closed position of the frame 2, following the displacement of the opening 3 by a vehicle occupant between the open position and the closed position. When such a signal is detected by the detection module 10, it generates information indicating that the opening 3 is in the closed position relative to the frame 2. This information is intended to be used for example in the context the control of a device conditioned by the arrival in the closed position of the opening 3, for example to control the extinction of a lighting device or activate a refrigeration device in the context of the application of the opening system according to the invention compartment 3025157 12 storage. According to the invention, the detection module 10 is designed to be activated in the absence of a command instruction received by the control module 9. In other words, the detection module is activated as long as the control module does not receive no command instruction from for example the control button 12 or the event detection device 13 as seen above. Thus, in the absence of a command instruction received by the control module 9, the detection module 10 monitors the appearance of a signal 10 characteristic of the arrival of the opening 3 in the closed position of the frame 2 following the movement of the opening 3 by a vehicle occupant between the open position and the closed position, from the electromagnet 7. More specifically, when the electromagnet 7 is not controlled by the control module 9, the electromagnet is in a passive state and the detection module 10 is activated to receive and monitor a current induced in the electromagnet 7, and more specifically in the coil 71 of the electromagnet 7, by the variation of magnetic field caused by the variation of position between the ferromagnetic element 5 and the permanent magnet 6 when the opening 3 is moved between the open position and the closed position. The electromagnet 7 is thus used to act as a sensor, the detection module 10 monitoring the induced current flowing through it when the opening 3 is moved between the open position and the closed position. When the opening 3 is close to the open position 25 and begins to be moved by a vehicle occupant to the closed position, the magnetic field variation and the induced current in the resulting electromagnet are low. , these two parameters increasing as the opening approaches the closed position. Also, the detection module 10 is designed to monitor the induced current in the electromagnet 7 and to conclude at the arrival of the opening 3 in the closed position of the frame 2, in other words to detect a signal representative of the arrival of the opening 3 in the closed position, when the current induced in the electromagnet 7 exceeds a predetermined detection threshold Sd. This detection threshold Sd is chosen in a suitable manner, in particular as a function of the characteristics of the electromagnet 7, of the ferromagnetic element 5 and of the magnet 6, and corresponds substantially to the current 5 induced in the electromagnet 7 when the opening 3 is moved from a position close to the closed position to the closed position. With reference to FIG. 5, an example of a control circuit for the control unit 8 of the opening system 1 according to the invention will now be described.
    [0016] In this FIG. 5, the control unit 8 is in the form of an electronic control card comprising a plurality of ports A, B, C, D, E, F. The port A belongs to the detection module 10. and constitutes a reception port whose utility will be described later. Port B belongs to control module 9 and constitutes a detection control port whose utility will be described later. The port C belongs to the control module 9, is electrically connected to the electromagnet 7 and constitutes a control port of the electromagnet 7 via which a control current, going in one direction in the case of a command the opening received by the control module 9 and in the opposite direction in the case of a lock command received by the control module 9, is sent to the electromagnet 7 via a resistor R and a switching transistor. The port D belongs to the control module 9 and is connected to a power supply source ALIM. The port E and the port F belong to the control module 9 and are electrically connected to the opening control button 12 and to the event detection device 13. As always visible in this FIG. 5, the opening system according to the invention furthermore comprises a switching element 11 electrically connected to the electromagnet 7 and to the detection module 10, and able to adopt an open state, in which the electromagnet 7 is isolated, in other words not electrically connected. , to the detection module 10, and an on state, in which the electromagnet 7 is electrically connected to the detection module 10. As seen above, the detection module 10 is activated only when no control instruction is available. received by the control module 9. Also, the switching element 11 is provided to adopt the on state as long as no command instruction is received by the control module 9, and to adopt the open state when the control module receives a control command.
    [0017] Such a switching element may take the form of a simple controlled switch. In the exemplary embodiment illustrated in FIG. 5, the switching element is in the form of an NPN transistor 11 having a base, a collector and an emitter. The base is connected to the detection control port B of the control module 9, the collector is connected to the electromagnet 7 and the transmitter is connected to the detection port A of the detection module 10. The transistor 11 is used here in commutation. When a control command is received by the control module 9, the control module 9 controls the electromagnet 7 via the control port C, and no current is sent by the control module 9 to the control unit 9. detection control port B so that the transistor assumes the open state. When no control command is received by the control module 9, a detection control signal is sent on the detection control port B of the control module 9. For the transistor 11 to assume the on state , it is necessary that the detection control signal sent on the detection control port B and received by the base of the transistor 11 exceeds a predetermined control threshold Sc, corresponding to the saturation limit intensity of the transistor 11.
    [0018] As mentioned above, in the embodiment illustrated in FIG. 5, the emitter of the transistor is connected to the detection port A of the detection module 10. Thus, when no control instruction is received by the module of 9, and that the transistor 11 is placed in the on state, a current can flow between the collector of the transistor 11 connected to the electromagnet 7 and the emitter of the transistor 11 connected to the reception port A of the detection module . In particular, under these conditions, an induced current Ci in the electromagnet 7, caused by the magnetic field variation between the ferromagnetic element 5 and the magnet 6 when the opening 3 is moved between the opening position and the closed position, is received on the reception port A of the detection module. The detection module 10 is designed to conclude at the arrival of the opening in the closed position of the frame, in other words to detect a signal representative of the arrival of the opening in the closed position, when this induced current exceeds a predetermined detection threshold Sd defined taking into account the physical characteristics of the electromagnet, the ferromagnetic element and the magnet. When a control command is received by the control module 9, no signal, or at least no predetermined upper command threshold signal Sc, is sent on the detection control port B, so that the transistor 11 is in the open state and the current can not flow between the electromagnet 7 and the detection module 10. The receiving port A is then isolated from the electromagnet 7 and the latter is controlled by the module control for making an opening or locking command. An example of operation of a sash system according to the invention will now be described with reference to FIG. 6, in which a method of detecting the arrival of the sash in the closed position of a frame may be realized.
    [0019] As shown in this FIG. 6, the operation of the opening system according to the invention starts with a step of checking whether a command instruction is received by the control module 9. If such a command instruction is received by the control module 9, for example following the actuation of the control button 12 25 by an occupant of the vehicle or the detection of an event by the event detection device 13, the reception by the detection module is forbidden 10 of the signal representative of the arrival of the opening 3 in the closed position, by sending no signal to the detection control port B, so that the transistor 11 is in the open state and the current can not 30 circulate between the electromagnet 7 and the detection module 10. The electromagnet 7 is then activated to perform the desired function (opening or locking of the opening) by means of a current sent by the control module 9 su r the control port of the electromagnet 7.
    [0020] A timing step is then performed, in particular to allow time for an occupant of the vehicle to manually move the opening 3 in the case of an opening instruction canceling the closing force or to maintain for a certain time a locking force reinforcing the closing force in the case of a lock command issued following the detection of a shock to the vehicle. The electromagnet 7 is then deactivated and the method returns to the step of testing whether a command instruction is received by the control module 9.
    [0021] If no command instruction is received by the control module 9, the detection module 10 is activated and the reception by the detection module 10 of the signal representative of the arrival of the opening 3 in the position of closing, by sending a signal iB on the detection control port B greater than the predetermined control threshold Sc, so that the transistor 11 is in the on state and the current can flow between the electromagnet 7 and the module 10. The current induced Ci in the electromagnet 7 by the magnetic field variation caused by the variation of position between the ferromagnetic element 5 and the magnet 6 when the opening is moved to the open position 20 and the closed position is then received by the reception port A of the detection module 10. This induced current Ci is then compared with a predetermined detection threshold Sd, and the detection module 10 detects the arrival of the opening 3 in the closed position when the induced current Ci received on the reception port A reaches this detection threshold Sd. The detection module 10 then generates information indicating that the opening 3 is in the closed position of the frame 2, this information can be used later for example to control a device conditioned by the position of the opening 3 relative to the frame 2 as mentioned above.
