Definitions

• the present invention relates to a control device for a motor vehicle and a control method of said control device.
• buttons on the dashboard of a car cockpit results in an increase in the number of buttons on the dashboard of a car cockpit.
• the number of buttons can not be increased to infinity, especially because of the complexity generated, limited space, accessibility or cognitive load.
• 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.
• buttons are centralize 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.
• the screens have three other major advantages: they allow on the one hand a direct interaction (co-implementation 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").
• 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 a application of touch screens respecting automobile constraints.
• the subject of the present invention is 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 a contact of 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 ⁇ 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 of a conventional push-button.
• the haptic feedback module is configured to generate amplitudes of displacements of the tactile surface:
• the acceleration increases with the increase in the displacement amplitude for the small displacements (lower than 38 ⁇ ). For displacements of greater amplitude, beyond 54 ⁇ , 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.
• 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 ⁇ with an acceleration of the displacement of the touch surface between 2 * G and 8 * G.
• amplitudes of displacements of the tactile surface are generated:
• the displacement amplitude of the tactile surface and the acceleration of the displacement of the tactile surface have interdependent values.
• 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.
• FIG. 1 represents an example of a control device for a motor vehicle
• - Figure 2 shows the acceleration values of the touch surface in number of G, as a function of the displacement values in ⁇ of the touch surface.
• 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 tactile surface 2 and a haptic feedback module 4 configured to vibrate the touch surface 2 in response to contact of the touch surface 2 by a finger or any other activation means (for example a stylus ) of a user who has, for example, modified or selected a command.
• a haptic feedback module 4 configured to vibrate the touch surface 2 in response to contact of the touch surface 2 by a finger or any other activation means (for example a stylus ) of a user who has, for example, modified or selected a command.
• Hapic means a return by touch.
• 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, enabling a dedicated function, selecting 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.
• the senor 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 ink conductive. 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.
• the contact sensor comprises flexible semiconductor layers sandwiched between for example a conductive layer and a resistive layer.
• a conductive 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.
• 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.
• the latter are arranged under the touch surface 2, 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).
• 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 m, 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.
• 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 displacement amplitude dR between and 110 ⁇ (FIG. 1) with an acceleration of the displacement of the tactile surface 2 between 2 * G and 8 * G, with G corresponding substantially to 9.8 m / s 2 .
• 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 haptic feedback module 4 is configured to generate amplitudes of displacements of the tactile surface 2 between 5 and 38 ⁇ for an acceleration of the tactile surface between 4.5 * G and 8 * G.
• the haptic feedback module 4 is configured to generate amplitudes between 54 and 110 ⁇ , for an acceleration of the displacement of the touch surface 2 between 2 * G and 4.5 * G.
• the haptic feedback module 4 is configured to generate displacement amplitudes of the tactile surface 2 between 5 and 38 ⁇ for an acceleration of the tactile surface 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.
• Two groups of points G1, G2 are schematically represented 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 ⁇ and the acceleration of the tactile surface is between 4.5 * G and 8 * G.
• a second group of points G2 represents the second sub-range for which the amplitudes of displacement are between 54 and 110 ⁇ , for an acceleration of the displacement of the tactile surface 2 between 2 * G and 4.5 * G.
• 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 ⁇ and the acceleration of displacement is between 2 * G and 8 * G.
• 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.
• 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.
• 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.
• the value of the acceleration must be increased with the increase in the amplitude of displacement for the small displacements (lower than 38 ⁇ ).
• the acceleration is also increased with the increase of the displacement but at lower values than for the small displacements.
• 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.
