Definitions

• the haptic feedback generated for example by the user manipulating a wheel is generally composed of resistance forces of variable values, creating hard points and bearings, corresponding to different commands for the devices controlled via the interface.
• the haptic feedback is advantageous by car because it requires little attention from the driver, in particular, it does not require the driver to look away from the road.
• the sound can be personalized and its signature can for example allow the identification of the car manufacturer.
• the volume of the sound return can be adapted to the sound environment of the passenger compartment, for example by being controlled according to a microphone arranged in the passenger compartment.
• the possibility is left to the user to completely or partially suppress the generation of sound returns or to modify the sound returns generated.
• the subject of the invention is also a method of controlling an interface of haptic feedback control as described above, characterized in that it emits a sound feedback to the user moving the movable element.
• the magnetorheological fluid module 3 may comprise a gripping element 5, integral with the movable element 6, that is to say rigidly connected to the movable element 6.
• the gripping element 5 is for example made of material with the movable member 6 or clipped on the movable member 6 or fixed by pin or by any other means known fixation.
• the gripping element 5 can be coupled to the movable element 6 via a gear system, chains, belts or any other mechanical means for ensuring a coupling between the gripping element 5 and the movable element 6.
• the haptic feedback comprises one or more haptic patterns defined by a signal representing the generated braking force or the magnetic field applied to the magnetorheological fluid 7, as a function of the position and / or the variation of position and / or the speed and / or speed variation and / or acceleration and / or a variation of the acceleration and / or direction of movement of the movable member 6.
• the position of the movable member 6 is for example the angular position for a rotating movable element 6.
• the sound return unit 18 is configured to generate a sound return, such as a sound simulating friction or mechanical indexing. It is thus possible to improve the quality and the precision of manipulation perceived by the user with a great freedom of choice for the sound accompaniment, making it possible to deliver singular performances to the existing solutions because it is possible to control the sound return without being dependent on mechanical elements.
• the sound can be personalized and its signature can for example allow the identification of the car manufacturer.
• the volume of the sound return can be adapted to the sound environment of the passenger compartment, for example by being controlled according to a microphone arranged in the passenger compartment. In addition, the possibility is left to the user to completely or partially suppress the generation of sound returns or to modify the sound returns generated.
• the sound returns are variable as a function of the position and / or the variation of position and / or the speed and / or the speed variation and / or the acceleration and / or the variation. the acceleration and / or direction of movement of the movable element 6.
• the sound return of a rotating mobile element 6 may be a function of the speed of rotation or the value of the torque of a mobile element 6 rotating.
• the sensor 21 may also be connected to the application unit 8 of a magnetic field for controlling the application unit 8 of a magnetic field to the magnetorheological fluid 7 generating a desired haptic feedback.
• the position and / or speed and / or acceleration sensor 21 may comprise, for example, a set of contacts and a brush in contact successively with some of the contacts during the displacement of the mobile element 6.
• the sensor 21 may be located at different locations near the movable element 6 and in particular on the side of the gripping element 5.
• the sound return comprises several sound patterns, all or part of which can be suppressed or replaced or modulated, for example in intensity and / or in duration depending on the speed of movement of the mobile element 6.
• a sound return is emitted as long as the displacement of the movable element 6 is distinct from a zero displacement, for example as long as the speed of the movable element 6 is not zero.
• the emitted sound return can thus for example simulate the friction of an index on an indexing ramp as soon as one begins to rotate the movable member 6.
• a sound return is emitted when a variation of the applied magnetic field and / or the braking force generated on a predetermined displacement is greater than a predetermined threshold. For example, a sound return is emitted for a decrease of the braking force generated to its lowest value.
• Several thresholds may be predetermined in relation to magnetic field variations or braking forces observed.
• the sound return is issued before the generation of the associated haptic feedback.
• a sound return is emitted after the generation of the associated haptic feedback, while no haptic feedback is generated.
• This sound feedback can be used to simulate some mechanical buttons for which a stop sound "click" is issued after the button has reached a stop. This case applies for example to mechanical buttons having significant frictional forces requiring a longer time of catching games.
• the sound return comprises a predefined number of sound patterns, lower, greater or equal to the number of haptic patterns of the associated haptic feedback. For example, a sound pattern is emitted only with a first haptic pattern of a series of haptic patterns.
• the cavity 11 is intended to receive on the one hand the magnetorheological fluid 7 and on the other hand an end of the movable element 6.
• the mobile element 6 is then partially immersed in the magnetorheological fluid 7.
• the base 9 also has an annular housing 12 which at least partially surrounds the cavity 11.
• the annular housing 12 receives one or more coil (s) which, with its (their) power supply (s) (not shown), forms the application unit 8 of a magnetic field on the magnetorheological fluid 7.
• the magnetic field created by a coil being proportional to the current flowing through it, it is possible to vary the intensity of the magnetic field created in the center of the coil by varying the supply of the coil.
• the variation of the intensity of the magnetic field applied to the magnetorheological fluid 7 makes it possible to vary the viscosity of the fluid and thus the friction force exerted by the fluid. It is thus possible to vary the force with which the mobile element 6 can be rotated to generate a haptic feedback specific to the user handling the mobile element 6.
