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 improves the feeling of the user, without hindering driving, which is well perceived and appreciated by users, and which can be discriminable from other signals for an application of touch screens respecting the automotive constraints.
- the subject of the present invention is a control device for a motor vehicle comprising:
- a touch surface comprising a contact sensor adapted to measure a pressing pressure on the touch surface for a predetermined duration, and a sensory feedback module configured to generate a tactile feedback in response to contact of the touch surface
- the sensory feedback module is configured to determine the profile of the sensory feedback to be generated as a function of the variation of the bearing pressure measured on the touch surface for the predetermined duration.
- the proposed control device improves the impression of support by matching the profile of the sensory feedback with the variation of the support pressure. Distinct sensory feedback is generated depending on whether the pressure pressure variation is strong, medium or low. The sensory feedback can thus be different for the same user at each of his actions according to the force exerted on the tactile surface.
- the sensory feedback module is configured to evaluate the speed of variation of the pressing pressure and to determine the profile of the sensory feedback generated as a function of the variation of the pressing pressure and as a function of the speed of variation of the pressing pressure for the predetermined duration,
- the sensory feedback module is configured to determine the acceleration of variation of the bearing pressure and for determining the profile of the sensed feedback generated as a function of the variation of the pressing pressure and as a function of the acceleration of variation of the pressing pressure for the predetermined duration.
- the correspondence between the feeling and the support is further improved when the profile of the sensory feedback is based on a pair of parameters representative of the pressing pressure.
- the sensory feedback profile is for example based on the pair of parameters defined by the variation of the bearing pressure and the rate of variation of the bearing pressure or on the torque defined by the support pressure vanation and the acceleration of variation of the support pressure.
- a dry and strong support thus causes a sensory feedback distinct from a slow and weak support or a weak and weak support or a slow and strong support.
- the sensory feedback comprises at least two components selected from a vibration, a sound and a visual representation.
- a sensory feedback comprising at least two components of different sensory modalities has the advantage that for the user, the presentation of one of the components will cause the activation of the other.
- the presentation of a visual primer previously associated with a sound component facilitates the perceptual processing of sound targets for the user, the mere presentation of the visual component reactivating the associated sound component.
- the various components of the sensory feedback are for example generated so as to be perceived with a time shift.
- the visual component is for example generated so as to be perceived before the sound and / or vibration components.
- the vibration component is for example generated so as to be perceived before the sound component.
- the generations of the different components of the sensory feedback are shifted in time. This desynchronization of perceptions of the components of the sensory feedback makes it possible to better reproduce the temporal offsets of tactile, auditory or visual returns that may exist for conventional mechanical buttons, which are linked to their mechanical functioning.
- the sensory feedback module comprises a library of sensory returns indexed at least as a function of the pressing pressure.
- the sensory feedback module is configured to determine the profile of the sensory feedback from a preprogrammed control law at least as a function of the variation of the pressing pressure.
- the subject of the invention is also a method of controlling a control device for motor vehicle as described above in which a sensory feedback is generated in response to a contact of the tactile surface characterized in that the profile of the generated sensory feedback is determined as a function of the variation of the bearing pressure measured on the touch surface for a predetermined duration.
- the rate of variation of the pressing pressure is determined and the profile of the sensed feedback generated is also determined as a function of the speed of variation of the pressing pressure for the predetermined duration.
- the acceleration of variation of the bearing pressure is determined and the profile of the sensed feedback generated is also determined as a function of the acceleration of variation of the bearing pressure during the predetermined duration.
- a first sensory feedback is generated for a pressure variation of less than 1, 2N,
- a second sensory feedback is generated for a variation of pressing pressure between 1, 2 N and 1, 5N, and
- a third sensory feedback is generated for a pressure variation greater than 1.5N; the first, second and third sensory feedbacks being distinct from each other.
- the profile of a vibratory-type sensitive feedback is modified by modifying the value of at least one parameter chosen from the amplitude, the duration, the acceleration and the frequency of the vibration. .
- the first, the second and the third sensory feedbacks are, for example, vibrations, at least one parameter chosen from among the amplitude, the duration and the acceleration, has a value which increases with the increase of the pressure variation of support .
- the control method provides, for example, a delay time for which sensory feedback is not generated after the generation of the sensing feedback. This simulates a sensation of abutment of the depression.
- a sensory abutment feedback is generated after the generation of the back feel feedback.
- the sensory back-stop intermediate between the sensory back-rest and the sensory-loosened return, makes it possible to reproduce the mechanical sensation of stop perceived when a key reaches its abutment.
- support since the finger of the user remains pressed on the touch surface by exerting a slight pressure variation, even after a delay time, the user must keep the release control and therefore not activate a function without wanting if this is taken into account when released and if the variation of pressure of support is insufficient.
- the predetermined duration during which the variation of the pressing pressure is measured is, for example, less than 30 milliseconds.
- FIG. 1 represents an example of a control device for a motor vehicle
- FIG. 2 represents a vibratory feedback as a function of time (curve 2) matched to a user's pressing pressure on the tactile surface as a function of time (curve 1), and
- Figure 3 illustrates a control method of a control device.
- 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 sensory feedback module 4 configured to generate a tactile feedback in response to contact of the touch-sensitive surface 2 by a finger or any other activation means (for example a stylus). a user having, for example, modified or selected a command.
- 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 capable of measuring a pressing pressure on the touch surface for a predetermined duration.
- 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 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.
- the contact sensor comprises semiconductor layers flexible sandwiched between for example a conductive layer and a resistive layer.
- a suitable voltage By exerting pressure or slipping on the FSR layer, its ohmic resistance decreases thus allowing, by application of 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 sensory return is for example a haptic feedback, we call "haptic", a return by touch.
- the haptic feedback is for example a vibratory or vibrotactile signal.
- the sensory feedback module 4 comprises at least one actuator 3 connected to the plate of the touch surface 2, to generate a vibration as a function of a signal from the contact sensor.
- the vibration is for example directed in the plane of the touch surface 2 or orthogonally to the plane of the touch surface 2 or directed in a combination of these two directions.
- 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 actuator 3 are arranged under the tactile 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 ⁇ , 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 sensory feedback module 4 is configured to determine the profile of the sensory feedback to be generated as a function of the pressure measured on the touch surface 2 for a predetermined duration.
- the profile of the sensory feedback defines the general form of the sensory feedback, that is to say, its pace or all the parameters allowing to characterize it.
- the pressing pressure on the touch surface 2 is measured.
- the pressing pressure is measured over a predetermined time dt, for example by averaging the pressing pressure over the predetermined duration dt.
- the predetermined duration dt is preferably less than 30 milliseconds, such as of the order of 20 milliseconds.
- the profile of the sensory feedback to be generated is determined as a function of this measured pressure pressure variation, for example from a library of sensory returns indexed as a function of the pressure variation of support.
- the profile of the sensory feedback is selected from among several sensory feedback profiles prerecorded in the library.
- the profile of the sensory feedback is determined from a preprogrammed control law that makes it possible, for example, to calculate a parameter of the profile as a function of the variation of the bearing pressure or to transform the variation of bearing pressure. in a sensitive return.
- a first sensory feedback is generated for a weak support corresponding to a pressure variation of support less than 1, 2N
- a second sensory feedback is generated for a mean support corresponding to a variation of pressure of support between 1 , 2N and 1, 5N
- a third sensory feedback is generated for a strong support corresponding to a pressure variation greater than 1.5N.
- the first, second and third sensory feedbacks are distinct from each other.
- the profile of the sensory feedback is modified by modifying the value of at least one parameter chosen from the amplitude, the duration, the acceleration and the frequency of the vibration.
- the value of these parameters increases for example with the increase of the variation of pressing pressure.
- the first, second and third sensory feedbacks are vibrations and that at least one parameter selected from amplitude, duration and acceleration have values which increase with the increase of the variation of support pressure.
- the amplitude of the first vibratory feedback has a value lower than the amplitude of the second vibratory feedback, the amplitude of the second vibratory feedback being less than the amplitude of the third vibratory feedback.
- These three sensory feedback profiles are not, for example, stored in memory in a library corresponding to the corresponding pressure variations.
- the sensory feedback module 4 is configured to evaluate the speed of variation of the pressing pressure and to determine the profile of the sensed feedback generated as a function of the variation of the pressing pressure and as a function of the rate of variation of the pressing pressure for the predetermined duration.
- the sensory feedback module 4 is configured to determine the acceleration of variation of the pressing pressure and to determine the profile of the sensed feedback generated as a function of the variation of the pressing pressure and in function the acceleration of variation of the support pressure during the predetermined duration.
- the correspondence between felt and support is further improved when the sensory feedback profile is based on a pair of parameters representative of the variation of the pressure of support.
- the profile of the sensory feedback is for example based on the variation of the pressure of support and the speed of the variation of the pressure of support or on the variation of pressure of support and on the acceleration of the variation of the pressure support.
- a dry and strong support thus causes a sensory return distinct from a slow and weak return or a weak and weak support or a slow and strong support.
- the sensory feedback whose profile is a function of the variation of the bearing pressure measured on the touch surface 2 during the predetermined time dt is for example generated after crossing a threshold.
- This threshold allowing the triggering of the generation of the sensory feedback can be a threshold of variation of the support pressure, of speed or of acceleration of variations of pressing pressure or else of variation of the contact area of the finger.
- the sensory feedback comprises for example at least two components chosen from a vibration, a sound and a visual representation.
- a sensory feedback comprising at least two components of different sensory modalities, has the advantage that for the user, the presentation of one of the components will cause the activation of the other.
- the presentation of a visual primer previously associated with a sound component facilitates the perceptual processing of sound targets for the user, the mere presentation of the visual component reactivating the associated sound component.
- the various components of the sensory feedback can be provided to generate the various components of the sensory feedback so that they are perceived with a shift in time, for example by shifting in time their respective generation.
- the different components of sensory feedback are not necessarily perceived simultaneously.
- This desynchronization of the perceptions of the components of the sensory feedback can correspond as on a conventional push button to the delay necessary for the ascent from the pressed key to its state of rest and the resulting noise.
- the proposed control device 1 improves the impression of support by matching the profile of the return sensitive with the variation of pressure of support. Distinct sensory feedback is generated depending on whether the support is loud, medium or weak.
- Figures 2 and 3 illustrate an embodiment of the control method of the control device wherein the sensory feedback comprises at least one vibratory feedback simulating the "pushed-released" of a button-type button.
- the bearing pressure (curve 1) on the touch surface 2 is measured.
- the pressing pressure is measured on a first predetermined duration dt1, such as of the order of 20 milliseconds.
- the profile of a sensory back-rest R1 to be generated is determined as a function of this variation of measured pressure, for example from a library of sensory returns indexed as a function of the bearing pressure or again, from a control law preprogrammed according to the support pressure.
- the bearing feedback R1 to generate a first vibration for a bearing pressure of less than 1, 2N, a second vibration for a pressure of between 1, 2N and 1.5N, and a third vibration for a bearing pressure greater than 1.5N.
- the duration of the vibration varies with the measured bearing pressure.
- a first vibration has a duration less than the duration of the second vibration and the duration of the second vibration is less than the amplitude of the third vibration.
- the vibration of the sensing feedback R1 whose profile is a function of the variation of the bearing pressure measured on the touch surface 2 during this first predetermined time dt1 (curve 2) is generated, for example, after the bearing pressure has passed a first pressure threshold S1.
- the sensory feedback feedback R1 perceived by the user can then be different depending on whether he pressed strongly or not on the touch surface 2.
- the determination of the sensory feedback R1 can also be determined the function of a second parameter, such as the rate of variation of the pressure of support or the acceleration of variation of the pressing pressure.
- the sensory feedback R1 may vary depending on the value of this second parameter.
- the vibration is for example produced by a sinusoidal control signal sent to the actuator 3.
- the vibration felt extends over the vibration duration Dv (curve 2), greater than the duration of the control signal.
- a delay time Da at least of the order of 20 ms between the generation of the two control signals of the sensory and relaxed feedbacks, during which no sensory feedback is generated.
- no control signal is sent to the actuator 3 after the one generating the sensing feedback R1 during a delay time Da of 20ms, a duration Da 'of about 10ms from the end of the vibration of the tactile surface 2 of the sensing feedback R1. This simulates a sensation of abutment abutment.
- a sensory abutment feedback is generated after the generation of the sensing back-rest R1, for example at the end of the vibration of the touch-sensitive surface 2 of the sensing back-rest R1 and / or after the crossing.
- a pressure threshold to simulate the sensation of thrust abutment between the generation of sensory feedback and relaxation. The sensory feedback stop thus makes it possible to reproduce the perceived mechanical sensation when a depressed key reaches its mechanical stop.
- a decrease in the pressing pressure is measured over a second predetermined duration dt2, which may be different from the first predetermined duration dt1.
- the profile of the sensory feedback loop R2 to be generated is determined as a function of this measured bearing pressure, for example from a library of sensory returns indexed as a function of the pressing pressure, or again from 'a law of order preprogrammed according to the pressing pressure.
- the vibration of the relaxed return return R2 has a smaller amplitude than the amplitude of the vibration of the back rest sensing R1, which makes it possible to further copy the effect of an existing button.
- a third step 103 the vibration of the relaxed release feedback R2 whose profile is a function of the variation of the bearing pressure measured on the touch surface 2 during this second predetermined duration dt2 (curve 2) is generated for example after the pressure drop has passed a second pressure threshold S2.
- the sensory stop feedback or the flow of the delay time Da do not necessarily condition the emission of the sensory feedback of release R2.
- a sensitive return of release R2 can be generated while the sensory stop return has not yet been sent or before the expiration of the delay time Da, for example because the support pressure has stopped increasing and decreases sufficiently before the end of the vibration of the tactile surface 2 of the sensory feedback R1.
- the total duration of the sensory feedback including the first predetermined duration dt1, the duration of vibration Dv, the duration of the sensory feedback and rest periods R1, R2 and the delay time Da or the sensory feedback of stop 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 by the user.
- the frequency of the vibration of the touch surface 2 is for example between 60 and 200Hz, such as 120Hz.
