    [0001] The present invention relates to a control device for a motor vehicle and a control method of said control device. In recent years, cars have become easier to handle with the emergence of new emerging technologies (eg power steering, ABS, cruise control, reversing radar etc ...). Paradoxically, however, the number of functions to be controlled while driving has also increased significantly. This can lead to some complexity related to the poor knowledge of the use of these features and their diversity. The car has become a real living space, perceived as a center of personal and interconnected communication: with for example MP3 player, GPS, connection with mobile phones. The introduction of these new features results in an increase in the number of buttons on the dashboard of a car cockpit. However, the number of buttons can not be increased indefinitely, especially because of the complexity generated, the limited space, the accessibility or the cognitive load. In addition, the interaction of the driver with the systems in the car can reproduce a situation of attentional overload in which the driver can not handle at best all the information of the driving task, resulting in errors and a time of longer detection. One possibility is to centralize the buttons by replacing them with a touch screen. This makes it possible to continue to increase the number of functions, these becoming programmable and reconfigurable and exposed temporarily or permanently depending on the context or the activated function. The screen thus includes a possibility of multifunctionality, while dematerializing the buttons and being customizable. In addition, the screens have three other major advantages: they allow on the one hand a direct interaction (co-implantation 25 of the display and input), on the other hand they are flexible (the display can be easily configured for a number of functions), and finally they are intuitive (familiar interaction method such as "point"). However, unlike in the case of a push button, when the driver interacts with a touch screen, he receives no feedback directly related to his action on the interface, other than the mere touch of his finger crashing on the screen. 'screen. In order to compensate for the loss of information caused by the substitution of conventional mechanical interfaces with touch screens, there is provision for the addition of feedback, such as haptic feedback, to provide system feedback to the user. . This return makes it possible to avoid the possible ambiguity of taking into account the action of the user by the system, likely to favor the appearance of dangerous situations. However, it must also avoid overloading the visual and auditory pathways already heavily involved in the driving task. Indeed, the use of touch screens in a motor vehicle must not disturb the attention of the driver. An object of the present invention is to provide a control device and a control method of said control device, which does not hinder driving, which is well perceived and appreciated by users, and which can be discriminable from other signals for an application of touch screens respecting automobile constraints. To this end, the present invention relates to a control device for a motor vehicle comprising a tactile surface and a haptic feedback module configured to vibrate the tactile surface in response to contact with the tactile surface, characterized in that the vibration of the generated tactile surface is obtained by displacements of the tactile surface of amplitude between 5 and 110 ium with an acceleration of the displacement of the tactile surface between 2 * G and 8 * G. The inventors have indeed discovered that for driving, a haptic feedback is better perceived by the user if the feeling is close to that of a manipulation 20 of a conventional push-button. The manipulation of a conventional push-button requiring a depression generally of the order of more than one millimeter, the inventors have found that by controlling on the one hand the acceleration values of the tactile surface and secondly the amplitudes of the displacements of the tactile surface, the felt vibration gave the illusion of the manipulation of the physical button. It is in fact the modification of these two physical parameters of the vibratory feedback, between 5 and 110 μm for the displacements of the tactile surface and between 2 * G and 8 * G for the acceleration of the displacement of the tactile surface, which are the most relevant to act on the feelings of users, allowing the vibratory feedback to be perceived as a button and thus to be better discriminated by the user, avoiding distraction during driving. According to an exemplary embodiment, the haptic feedback module is configured to generate amplitudes of displacements of the tactile surface: between 5 and 38 km for an acceleration of displacement of the tactile surface between 4.5 * G and 8 * G, and / or -3- - between 54 and 110 pm, for an acceleration of the displacement of the touch surface of between 2 * G and 4.5 * G. It can be seen that it is preferable to get closer to the "push-button feel" that the acceleration increases with the increase in the amplitude of displacement for the small displacements (lower than 3811m). For displacements of greater amplitude, beyond 541m, the acceleration is also increased with the increase of the displacement but with smaller values than for the small displacements. The duration of the vibration of the touch surface is for example less than 200 ms. The frequency of the vibration of the touch surface is for example between 60 and 200Hz.
    [0002] The subject of the invention is also a method for controlling a control device for a motor vehicle as described above, characterized in that the tactile surface is vibrated in response to contact with the touch surface by moving the touch surface on an amplitude between 5 and 110 1.1, m with an acceleration of the displacement of the touch surface between 2 * G and 8 * G.
    [0003] According to an exemplary embodiment, amplitudes of displacements of the tactile surface are generated: between 5 and 38 grn for an acceleration of the displacement of the tactile surface between 4.5 * G and 8 * G, and / or - included between 54 and 110 gn, for an acceleration of the displacement of the tactile surface between 2 * G and 4.5 * G. According to an exemplary embodiment, the displacement amplitude of the tactile surface and the acceleration of the displacement of the tactile surface have interdependent values. For example, increasing the value of the displacement amplitude of the touch surface is substantially proportional to the increase in the value of the acceleration of displacement of the touch surface. BRIEF DESCRIPTION OF THE DRAWINGS Other advantages and features will become apparent on reading the description of the invention, as well as on the appended figures which represent a non-limiting exemplary embodiment of the invention and in which: FIG. an example of a control device for a motor vehicle, and FIG. 2 represents the acceleration values of the touch-sensitive surface in number of G, as a function of the displacement values in .tm of the tactile surface. In these figures, the identical elements bear the same reference numbers.
    [0004] DETAILED DESCRIPTION FIG. 1 represents a control device for a motor vehicle 1, for example arranged in a control panel of the vehicle. The control device 1 comprises a touch-sensitive surface 2 and a haptic feedback module 10 configured to vibrate the touch-sensitive surface 2 in response to contact of the touch-sensitive surface 2 by a finger or any other activation means (for example a stylus) of a user having, for example, modified or selected a command. "Haptic" means a return by touch. Thus, haptic feedback is a vibratory or vibrotactile signal. The touch surface 2 is for example that of a touch screen. A touch screen is an input device that allows users of a system to interact with it through touch. It allows the direct interaction of the user on the zone he wants to select for various uses such as, for example, the selection of a destination address or a name in a directory, the air conditioning system settings, activation of a dedicated function, selection of a track from a list, or generally scrolling through a list of choices, selection, validation, and error. The touch surface 2 comprises a plate carrying a contact sensor to detect a pressing pressure or a movement of the finger or a stylus of the user. The contact sensor is for example a pressure sensor, such as using the FSR technology for "Force Sensing Resistor" in English, that is to say using pressure-sensitive resistors. SFR technology has a very good resistance and robustness, while having a high resolution. In addition, it is very reactive and precise, while being relatively stable over time. It can have a fairly long life, and can be used with any type of activation means, at a relatively low cost. According to a design of the FSR technology, the sensor operates by contacting two conductive layers for example by the action of the finger. One of the embodiments consists in covering a glass slab with a layer of conductive ink, on which is superimposed a sheet of flexible polyester, itself covered on its inner face with a layer of conductive ink. Insulating and transparent pads isolate the slab from the polyester sheet. The activation on the tactile surface produces a slight depression of the polyester layer, which comes into contact with the conductive layer of the glass slab. The local contact of the two conductive layers causes a modification of the electric current applied to the slab, corresponding to a voltage gradient. In another example, the contact sensor comprises flexible semiconductor layers sandwiched between for example a conductive layer and a resistive layer. By exerting pressure or sliding on the FSR layer, its ohmic resistance decreases allowing, by applying a suitable voltage, to measure the pressure applied and / or the location of the place where the pressure is exerted. In another example, the contact sensor is based on a capacitive technology. The haptic feedback module 4 comprises at least one actuator 3 connected to the plate of the touch surface 2, to generate the haptic feedback as a function of a signal from the contact sensor. The haptic feedback is a vibratory signal such as a vibration produced by a sinusoidal control signal or by a control signal comprising one or a succession of pulses, sent to the actuator 3. The vibration is for example directed in the plane of the touch surface 2 or orthogonal to the plane of the touch surface 2 or directed in a combination of these two directions. In the case of several actuators, these are arranged under the touch surface 2, 20 in different positions (in the center or on one side) or in different orientations (in the direction of the support on the surface or in another axis) . According to an exemplary embodiment, the actuator 3 is based on a technology similar to that of the speaker (in English: "Voice Coil"). It comprises a fixed part and a part movable in translation in an air gap of the fixed part, for example of the order of 200 μm, between a first and a second position, parallel to a longitudinal axis of the movable part. The moving part is for example formed by a movable magnet sliding inside a fixed coil or by a movable coil sliding around a fixed magnet, the movable part and the fixed part cooperating by electromagnetic effect. The moving parts are connected to the plate so that the movement of the moving parts causes the translational movement of the plate to generate the haptic feedback to the user's finger. This technology is easily controllable and can move large masses, such as a screen, at various frequencies and meets the strict automotive constraints that are low cost, good resistance to significant temperature variations, and ease of use. in place. The haptic feedback module 4 is configured to vibrate the touch surface 2 in response to a touch of the touch surface 2 so that the vibration of the touch surface 2 generated moves the touch surface 2 to a moving amplitude dR between 5 and 110 gm (Figure 1) with an acceleration of the displacement of the touch surface 2 between 2 * G and 8 * G, with G corresponding substantially to 9.8 m / s2. The inventors have indeed discovered that for driving, a haptic feedback is better perceived by the user if the feeling is close to that of a manipulation of a conventional push-button. The manipulation of a conventional push-button requiring a depression generally of the order of more than one millimeter, the inventors have found that by controlling on the one hand the acceleration values of the tactile surface 2 and other apart from the amplitudes of the displacements of the tactile surface 2, the vibration felt gave the illusion of the manipulation of the physical button. It is indeed the modification of these two physical parameters of the vibratory feedback, between 5 and 110 1.1.m for the displacements of the tactile surface 2 and between 2 * G and 8 * G for the acceleration of the displacement of the tactile surface 2 , which are the most relevant to act on the feelings of the users, allowing the vibratory feedback to be perceived as a button and thus to be better discriminated by the user during the driving. In the operating range for which the displacement amplitude is between 5 and 110 μm and the acceleration of displacement is between 2 * G and 8 * G, it is more precisely possible to define two sub-ranges.
    [0005] For example, it is provided that the haptic feedback module 4 is configured to generate the displacement amplitude of the touch surface 2 between 5 and 38 μm for an acceleration of the tactile surface between 4.5 * G and 8 * G. It is also possible that the haptic feedback module 4 is configured to generate amplitudes of between 54 and 110 gm, for an acceleration of the displacement of the touch surface 2 between 2 * G and 4.5 * G. According to an exemplary embodiment, the haptic feedback module 4 is configured to generate displacement amplitudes of the tactile surface 2 of between 5 and 38 grn for an acceleration of the tactile surface of between 4.5 * G and 8 * G and between 54 and 110 for an acceleration of the displacement of the touch surface 2 between 2 * G and 4.5 * G. Thus, depending on the type of function selected by the user, it is possible to generate a distinct haptic feedback but whose amplitude and acceleration of displacement remain in one of the two sub-ranges. Two groups of points G1, G2 are diagrammatically shown in FIG. 2. A first group of points G1 represents the first sub-range for which the displacement amplitude of the tactile surface 2 is between 5 and 38. gm and the acceleration of the touch surface is between 4.5 * G and 8 * G. A second group of points G2 represents the second sub-range for which the displacement amplitudes are between 54 and 110 μm, for an acceleration of the displacement of the tactile surface 2 between 2 * G and 4.5 * G. According to an exemplary embodiment, the displacement amplitude values of the touch surface and the acceleration values of the displacement of the corresponding tactile surface form at least one group of points whose shape is in an elliptical shape. The elliptical shape extends for example substantially along the diagonal of the operating range for which the amplitude of displacement is between 5 and 110 iirn and the acceleration of displacement is between 2 * G and 8 * G.
    [0006] In the example shown in FIG. 2, the displacement amplitude values of the touch surface and the acceleration values of the displacement of the corresponding tactile surface form two groups of points G1, G2 whose respective shape is part of a elliptical shape extending substantially along the diagonal P1, P2 of the respective sub-range.
    [0007] In addition, it can be provided that the displacement amplitude of the touch surface and the acceleration of the displacement of the touch surface have interdependent values, that is to say that the determination of one involves the determination of the 'other. For example, the increase in the magnitude of displacement of the touch surface is substantially proportional to the increase in the value of the acceleration of the displacement of the touch surface. The choice of the acceleration of the tactile surface as a function of the amplitude of the displacements of the tactile surface and vice versa, makes it possible to improve the feeling of the haptic feedback. More specifically, the correspondence between the choice of the amplitude of the displacements of the tactile surface 2 with the choice of the acceleration values makes it possible to refine the resemblance with a conventional push-button. It can be seen that an average amplitude displacement between 54 and 110 is better perceived and discriminated if it is associated with a weak acceleration of between 2 and 4.5 * G (P2 in FIG. 2). On the other hand, a displacement of low amplitude, between 5 and 38 len, is better perceived and discriminated if it is associated with an average acceleration of between 4.5 * G and 8 * G (P1 in the figure 2). Thus, to get closer to the "feel push button", the value of the acceleration must be increased with the increase of the amplitude of displacement for the small displacements (lower than 3811m). For displacements of greater amplitude, beyond 54grn, the acceleration is also increased with the increase of the displacement but at lower values than for the small displacements. According to an exemplary embodiment, the duration of the vibration of the touch surface 2 is short, that is to say less than 200 ms and preferably between 70 and 200 ms, such that between 110 and 140 ms. Short signals are indeed better perceived in these ranges of displacement and acceleration of the displacement of the touch surface 2. The frequency of the vibration of the touch surface 2 is for example between 60 and 200Hz, such as 120Hz.
