    Tactile interface module and method for generating a hautiaue feedback
    The present invention relates to a touch interface module and a method of generating a haptic feedback to transmit a haptic feedback to a user.
    In the automotive field, multifunction control modules, made for example in the form of a joystick or a rotary knob, are increasingly used to control electrical or electronic systems, such as an air conditioning system, an audio system or a navigation system.
    Such modules may be associated with a display screen and allow navigation in pull-down menus comprising various commands relating to the systems to be controlled.
    However, the presence of more and more numerous and complex functions leads to a multiplication of these modules. Also, to increase the number of integrated functions and improve the ergonomics of the human-machine interfaces, the use of a touch surface interface module, at a control surface or a touch screen, is considered an interesting development.
    When a user exerts pressure on the touch surface of such a sensor, it is possible to measure the applied pressure or force and / or determine the location of the place where the pressure or force is exerted. In this case, a support of the user is for example associated with the selection of a command.
    In addition, to indicate to the user that his order has been taken into account, whether in normal driving or stopping situation but also in a degraded situation (blind manipulation, significant cognitive load), it is important that the user has a haptic feedback so as to remain focused on the road by reducing the cognitive effort associated with verifying the achievement of its action on the tactile surface.
    For this purpose, haptic feedback control modules are already known comprising actuators, such as electromagnetic actuators, connected to the interface module for transmitting a vibration movement, so that the user perceives a haptic feedback informing him that his order has been taken into account.
    These electromagnetic actuators comprise a stator carrying an electromagnet and a movable core carrying one or more permanent magnets which can move in translation relative to the stator. By feeding the stator electromagnet, the moving core is moved and this movement is transmitted to the tactile surface.
    A second assembly, called "voice-coil" or "acoustic coil" in French since associated with the technical principle of the loudspeakers, is obtained by mounting in reverse mobile electromagnet with respect to one or more fixed permanent magnets .
    In particular, such a tactile interface module actuator with haptic feedback from the Applicant is known. The interface module comprises a tactile surface adapted to detect a support of a user and an actuator attached to the touch surface. The actuator comprises: - a frame, - a movable core cooperating with the frame, intended to be driven in movement between extremal positions to generate the haptic feedback, and - a stator having an electromagnet and configured to be able to drive the mobile core according to a translation movement back and forth.
    By an inertial effect, the movement of the movable core by the stator is transmitted to the frame which in turn transmits the vibration movement to a touch surface to which the actuator is attached.
    At rest, the movable core is in a floating rest position, held by springs.
    Once the electromagnet is powered by alternating signals, the amplitude of displacement in translation according to reciprocating movements of the core increases until it reaches a maximum and then the supply of the electromagnet is stopped.
    However, even if the power supply of the electromagnet is stopped, the induced mechanical waves continue to propagate on the touch surface and the vibrations fade only gradually.
    Studies of the Applicant have shown that the duration of the evanescent vibrations can reach 20ms and that these vibrations can remain perceptible long enough by a user.
    This can be inconvenient if it is necessary to transmit to the user haptic feedback that succeeds one another quickly with very short time intervals, especially less than 20 ms.
    Moreover, it turned out that a frank and percussive haptic feedback is better perceived by a user than a haptic feedback that spreads over time. The invention aims to at least partially overcome the above drawbacks, in particular by providing a haptic feedback tactile interface module with improved haptic feel, especially more frank. To this end, the subject of the invention is a touch interface module with haptic feedback, comprising: a tactile surface capable of detecting at least one characteristic of a support of a user, at least one haptic feedback actuator configured to transmit a haptic feedback to the tactile surface, - a processing and control unit connected on the one hand to the tactile surface and on the other hand to said at least one actuator, characterized in that the processing unit and the control is configured to activate the haptic feedback actuator in a first time window so as to induce at least one mechanical wave propagating on the touch surface able to be felt as a haptic feedback and in a second time window of in order to generate at least one mechanical pulse out of phase with the mechanical wave in order to attenuate this mechanical wave.
    The haptic feedback tactile interface module may further have one or more of the following features, taken alone or in combination.
    In one aspect, the processing and control unit is configured to activate the haptic feedback actuator in a second time to generate a plurality of mechanical pulses out of phase with the mechanical wave to attenuate this mechanical wave. .
    It can be provided that at least one control signal sent by the processing and control unit for activating the actuator and generating a phase-shifted mechanical pulse is shorter than a control signal sent by the processing unit and control for activating the actuator to induce at least one mechanical wave propagating on the touch surface adapted to be felt as a haptic feedback.
    In one aspect, the actuator activation control signal for generating a phase shifted mechanical pulse is an isolated signal.
    According to another aspect, the successive activation control signals of the actuator making it possible to generate a succession of out-of-phase mechanical pulses are oppositely polarized alternately.
    In yet another aspect, the energy of the out-of-phase mechanical pulses decreases.
    Said at least one out of phase mechanical pulse is in particular in phase opposition with respect to the mechanical wave.
    In addition, said at least one actuator may comprise: - a frame intended to be in contact with the touch interface by a contact wall for transmitting a haptic feedback to the tactile surface, - a stator connected to the frame, - a mobile core connected by at least one elastic element to the frame and intended to be driven in motion by the stator to generate the haptic feedback, - an electromagnet and at least one permanent magnet, one of which is carried by the stator and the other by the core mobile, and - a damper disposed between the movable core and the contact wall.
    Said elastic element can be dimensioned so that in the unpowered state of the electromagnet, the movable core applies a bearing force towards the contact wall and that in the energized state of the electromagnet according to a predefined polarization, the movable core moves away from the contact wall.
    The spring stiffness of said damper is between 7.5 and 12.5 times, in particular 10 times greater than the spring stiffness of said elastic element.
    Said damper is for example made in the form of a layer of an elastomer, in particular silicone.
    According to another aspect, the damper has a hardness of between 25 and 35, in particular 30 shore A. The invention also relates to a method for generating a haptic feedback in a haptic feedback tactile interface module comprising a surface tactile device adapted to detect a support of a user as defined above, characterized in that it comprises the steps according to which: according to a first step, at least one mechanical wave propagating on the tactile surface adapted to be felt as a haptic feedback, according to a second step, generates at least one mechanical pulse out of phase with the mechanical wave to mitigate this mechanical wave.
    During the second step, it is possible to generate several mechanical pulses out of phase with the mechanical wave in order to attenuate this mechanical wave.
    In one aspect, an actuator activation control signal for generating a phase-shifted mechanical pulse is shorter than an actuator activation control signal for inducing at least one mechanical wave propagating on the actuator. the tactile surface that can be felt as a haptic feedback.
    In another aspect, the activation control signal of the actuator for generating a phase-shifted mechanical pulse is an isolated signal.
    The successive activation control signals of the actuator making it possible to generate a succession of out-of-phase mechanical pulses are polarized, in particular in opposite directions alternately.
    In yet another aspect, the energy of the out-of-phase mechanical pulses decreases.
    Said at least one out of phase mechanical pulse is for example in phase opposition with respect to the mechanical wave. Other advantages and characteristics will appear on reading the description of the following figures, given by way of non-limiting example. FIG. 1 is a schematic side view of an embodiment of a touch interface module with an actuator, FIG. 2 is a schematic perspective view of the actuator of FIG. 1, FIG. 3 is a schematic perspective exploded view of the actuator of FIG. 2; FIG. 4 is a diagrammatic view in longitudinal section of the actuator of FIG. 2; FIG. 5 is a graph of control signals applied to FIG. an actuator; FIG. 6 is a flowchart of one embodiment of a method for generating a haptic feedback; and FIGS. 7 and 8 show graphs representing oscillations of the touch surface as a function of time, for two separate cases.
    In all figures the same references apply to the same elements.
    In some figures, a Cartesian coordinate system X, Y, Z is indicated in order to better understand the orientation of the elements relative to one another. In the present disclosure, the direction Z is generally perpendicular to a touch surface, provided that it is flat and the X-Y plane is parallel to the plane of this touch surface.
    The achievements described are examples. Although the description refers to one or more embodiments, this does not necessarily mean that each reference relates to the same embodiment, or that the features apply only to a single embodiment. Simple features of different embodiments may also be combined to provide other embodiments.
    FIG. 1 is a diagrammatic representation of an embodiment of a haptic feedback tactile interface module 1 comprising a tactile surface 3 capable of detecting a support of, for example, a finger 5 of a user, and at least one a feedback actuator 7 haptic. The number of actuators 7 may be two, three, four or more and depends in particular on the size of the touch surface 3.
    The tactile feedback interface module 1, for example for a control panel of a motor vehicle, or for a central console of a motor vehicle, makes it possible to control electrical or electronic systems of the vehicle, and can transmit a haptic feedback to a user having, for example, modified or selected a command so as to ensure that the user takes into account the modified or selected command.
    The touch surface 3 can be flat, but one can also consider curved or curved shapes, or even hollow forms. The touch-sensitive surface 3 is for example equipped with a capacitive or resistive sensor for detecting at least the position of the finger 5 on the tactile surface 3 and possibly also the trace of the movement of the finger 5 and / or the pressure of the finger 5 exerted on the touch surface 3.
    This detection of the position of the finger 5 is related for example to a display menu having pictograms and generates for example a control signal for controlling various equipment of a vehicle such as an air conditioning system, an audio system, a control system. telephony system and others.
    The embodiment of FIG. 1 can be designated as a so-called "suspended actuator" mode. Suspended means that the actuator 7 is not connected to a frame of the touch interface module 1, but only attached to the touch surface 3.
    Of course, one can also consider other assemblies of the actuator 7 without departing from the scope of this presentation. The actuator 7 thus forms a well-defined functional block, easily mountable and removable from the interface module 1. In fact, this functional block is simply screwed or clipped to the touch surface 3, and can therefore be interchanged quickly. The actuator 7 may optionally be glued for a less expensive fixing at the expense of interchangeability.
    The interface module 1 further comprises a processing and control unit 8 connected on the one hand to the touch surface 3 and on the other hand to the actuator 7. The processing and control unit 8 is for example a programmable component comprising a processor, RAM memory and storage memory and executes instructions of a registered software. It can be an ASIC for "application specified integrated circuit" in English, that is to say an application-specific integrated circuit or a programmable device of the mini-PC type. The processing and control unit 8 can also be connected to a not shown display, for example a display screen such as an LED or LCD panel, for displaying control menus of various equipment of the vehicle.
    In order to give a haptic feedback to the user whose attention must not deviate from the road in front of him, the taking into account of a command is signaled by the activation of the actuator 7 whose movement is transmitted to the touch surface 3.
    FIGS. 2 to 4 show an exemplary embodiment of an actuator 7, but other actuator structures or variants are conceivable. The actuator 7 comprises a frame 11 having a contact wall 13 which is fixed against the touch surface 3 to transmit a haptic feedback. The actuator 7 further comprises a stator 15 connected to the frame 11 for example by clips. The stator 15 carries an electromagnet 17, for example formed by a winding of an electrical wire, in particular copper.
    The stator 15 surrounds a movable core 19 to be able to animate the movable core 19 in translation in two opposite directions, perpendicular to the contact wall 13, in the direction Z, to generate the haptic feedback. The mobile core 19 comprises in particular permanent magnets 20 made in the form of platelets. These permanent magnets 20 are mounted in a stirrup 22, for example made of plastic and having an E-shaped cross section.
    The branches of the stirrup 22 also carry ferromagnetic metal plates 24 to give the mobile core 19 a larger mass in order to increase the kinetic energy of the mobile core 19 and to concentrate the field lines generated by the permanent magnets 20 .
    The movable core 19 is trapped between the contact wall 13 and the stator 15 and subjected to the force of at least one, in this case two elastic elements 21.
    These elastic elements 21 are in the present embodiment for example springs, in particular helical thrust springs, which are respectively disposed on two opposite lateral sides of the movable core 19. More precisely, a spring end is supported on the yoke 22 and the other end bears against the stator 15.
    It is also possible to use an elastic material for the elastic elements 21, such as a urethane type expanded polymer, an ionomer (ionically crosslinked polymer), or rubber.
    The annular central portion of the stator 15 carrying the windings of the electromagnet 17 cooperates with the branches of the stirrup 22 at "E", and guides the translational movement along Z of the movable core 19. The actuator 7 may comprise a damper 23 located between the movable core 19 and the contact wall 13. The damper 23 is for example made in the form of a layer or wafer of an elastomer, in particular silicone, which can be overmolded on the movable core 19 and / or be assembled on the movable core 19 by form conjugation as shown in Figure 3. As seen in Figures 2 and 4, the damper 23 is fixed on the back of the stirrup 22 at "E".
    According to a variant not shown, the damper 23 is fixed on the contact wall 13. However, it is preferable that the damper 23 is fixed to the movable core 19 to increase the mass of this moving assembly and therefore the kinetic energy transmitted during the impact on the contact wall 13. The damper 23 has in particular a hardness of between 25 and 35, in particular 30 shore A.
    The element (s) elastic (s) 21 is / are dimensioned (s) and biased so that in the unpowered state of the electromagnet 17, the movable core 19 applies a support force in the direction of the contact wall 13, so that the damper 23 is pushed against the contact wall 13. In the energized state of the electromagnet according to a predefined polarization, the movable core 19 deviates from the contact wall 13.
    The spring stiffness of said damper 23 is between 7.5 and 12.5 times, in particular 10 times greater than the spring stiffness of said elastic element 21.
    Fig. 5 shows a graph of control signals as a function of time applied to an actuator 7 and Fig. 6 shows a flowchart of a method of generating a haptic feedback according to one embodiment.
    According to a first step 100 during the time window T1, on receiving a signal from the touch surface 3 caused by a support of a finger 5, the processing and control unit 8 sends, for example, according to a first step. step 100-1 a first control signal 200-1. The first control signal 200-1 has a predefined first polarization, for example in square form for supplying the electromagnet 17 with current in a first direction along the direction Z so as to move the movable core 19 away from the contact wall 13 of the frame 11 against the force of the elastic elements 21 (the compression springs are compressed).
    The elastic elements 21 thus store in this phase a portion of the kinetic energy imparted to the mobile core 19.
    Of course, the unit 8 can be configured to supply the electromagnet 17 directly with current. But according to a variant, it can also send a control signal for example to a power supply relay of the electromagnet 17.
    The duration of this first control signal 200-1 is long enough for the mobile core 19 to deviate to the maximum, for example a duration of between 4 ms and 6 ms, in particular 5 ms.
    Then, according to a second substep 100-2, the processing and control unit 8 sends a second control signal 200-2 with a second predefined polarization opposite to the first polarization, for example also of square shape. This second control signal 200-2 reverses the current direction to invert the magnetic field so as to propel the movable core 19 towards the contact wall 13 of the frame 11 and keep the movable core 19 bearing against this contact wall 13. The elastic elements 21 assist in this phase the movement of the movable core 19 (the thrust springs relax).
    Since the moving core 19 here only makes one go and one return, a "percussive" haptic feedback is obtained as an impact that can easily be felt by the user's finger.
    The duration of this second control signal 200-2 has a duration of between 4 ms and 6 ms, in particular 5 ms.
    Of course, the durations of the control signals 200-1 and 200-2 may be different. We can also consider different forms of control signals and different amplitudes without departing from the scope of this presentation.
    This first step 100 thus serves to activate the haptic feedback actuator 7 so as to induce at least one mechanical wave propagating on the tactile surface 3 able to be felt as a haptic feedback.
    FIG. 7 shows the oscillations on the tactile surface 3 in the case where only this first step 100 is performed.
    As can be seen, one sees on the one hand in the time window T1 a signal which corresponds to the mechanical wave induced by step 100 and on the other hand in the time window T2 a signal corresponding to the wave evanescent mechanics whose amplitude decreases little by little and which can be troublesome.
    We therefore aim to attenuate, if possible very strongly, this evanescent mechanical wave.
    For this purpose, during a second step 102 during a time window T2, the haptic feedback actuator 7 is activated so as to generate at least one out of phase mechanical pulse, in this case three mechanical pulses out of phase with respect to the mechanical wave to attenuate this mechanical wave. The phase shift is in particular in phase opposition to obtain maximum attenuation. For this purpose, the processing and control unit 8 sends, for example according to a first substep 102-1, a first signal 202-1 with the second predefined polarization, for example in square form to supply the electromagnet 17. by running in the second direction in the direction Z so as to press the movable core 19 with the damper 23 against the contact wall 13. As can be seen, the first control signal 202-1 has the same polarization and the same amplitude as the second control signal 200-2, but it is shorter than the latter, for example between 1.5ms and 3ms, typically 2ms.
    It is also noted that the control signal 202-1 is isolated, that is to say just before and after the control signal 202-1, the actuator 7 is not powered.
    Then according to a second substep 102-2, a second control signal 202-2 with the first predefined polarization is sent to the electromagnet 17, which has the effect of moving the movable core 19 away from the contact wall 13 of the frame 11 against the force of the elastic elements 21, but less than in the first substep 100-1 since the control signal 202-2 has a smaller amplitude. The control signal 202-2 therefore has an inverted polarization with respect to the control signal 202-1 and a smaller amplitude in absolute value than the control signal 202-1. The control signal 202-2 is also an isolated signal.
    Finally according to a third sub-step 102-3, a third signal 202-3 with the second predefined polarization is sent to the electromagnet 17, which has the effect of supporting the movable core 19 with the damper 23 against the wall 13. As can be seen, the control signal 202-3 has the same polarization but a smaller amplitude than the control signal 202-1. The control signal 202-3 is also an isolated signal.
    It can thus be seen that the control signals 202-1, 202-2 and 202-3 are pulses polarized in opposite and alternating manner and that their energy, which corresponds to the area of the pulses, decreases. The effect of the control signals 202-1, 202-3 and 202-3 of the second step 102 on the evanescent mechanical wave is shown in FIG. 8. With respect to FIG. 7, it is clearly seen that the corresponding signal to the evanescent mechanical wave is greatly diminished.
    For a user, the haptic feedback appears more impactful and shorter.
    It is therefore understood that the out of phase mechanical pulses make it possible to have a haptic feedback more frank and thus better felt by the user.
    The position of the control signals 202-1, 202-2 and 202-3 naturally depends on various parameters such as, for example, the size of the touch surface 3, the material of the touch surface 3, the suspension of the touch surface 3 etc.
    The time position of the control signals 202-1, 202-2 and 202-3 and their amplitudes for a given configuration of a haptic feedback interface module 1 can be obtained in an iterative manner as follows:
    For example, an accelerometer is placed on the touch surface 3 to measure the mechanical wave or waves on the touch surface 3 and the output of the accelerometer is connected to an oscilloscope.
    Then the first step 100 is performed to induce a mechanical wave on the touch surface 3 and a graph similar to that of FIG. 7 is obtained.
    Then, a first control signal 202-1 is sent to supply the electromagnet 17 and generate a first mechanical pulse 202-1 in phase opposition with the mechanical wave induced by the first step 100.
    The attenuation of the mechanical wave is noted to determine the new temporal position of the bellies of the mechanical wave. Then, the electromagnet 17 is supplied with the second control signal 202-2 by placing this second signal 202-2 with respect to the temporal position of the bellies of the mechanical wave noted above so as to be in phase opposition with the evanescent mechanical wave. It is again noted the attenuation effect of the mechanical wave induced by the two control signals 202-1 and 202-2 to determine the new temporal position of the bellies of the mechanical wave. We start again by supplying the electromagnet 17 with the third control signal 202-3 by placing this third signal 202-3 with respect to the temporal position of the bellows of the mechanical wave previously noted so as to be in phase opposition with the evanescent mechanical wave.
    Once the values and the temporal position of the pulses of the control signals have been identified, they can be programmed as control instructions in one of the memories of the processing and control unit 8.
    It is thus clear that the specific excitation of the actuator 7 during the time window T2 makes it possible to strongly reduce the evanescent mechanical waves on the tactile surface 3 and thus to make the haptic feedback more perceptible to the user.
    Furthermore, in the case of a touch surface 3 equipped with several actuators 7, it is generally sufficient to activate a single actuator 7 during the time window T2 to obtain a satisfactory attenuation of the evanescent mechanical wave.
    However, it is also possible to activate also several actuators 7 during T2, or else to actuate the actuators 7 in turn, for example one for the control signal 202-1, another for the control signal 202- 2 and a third for the control signal 202-3.
    Of course, other variants are conceivable without departing from the scope of this presentation. Thus the electromagnet 17 can be carried by the movable core 19 and the permanent magnet 20 by the stator for a "voice-coil" configuration.
