Definitions
- the present invention relates to a control interface for a motor vehicle for transmitting a haptic feedback to a user to inform him of the taking into account of a command.
- the invention also relates to a method of controlling said haptic feedback control interface.
- 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 in the car because it requires little attention from the driver.
- Interfaces having a magnetorheological fluid capable of creating a braking force to a rotating element in the fluid when a magnetic field is applied to the fluid because the viscosity of the magnetorheological fluid changes with the intensity of the fluid. magnetic field applied.
- the magneto-rheological fluids can thus generate a braking force on the rotating element immersed in the fluid.
- the fluidity increases or decreases, the user perceiving a change of effort.
- the intensity of the magnetic field may have a slot shape for which the intensity is zero or low except at the indexing positions where this intensity is strong so as to create a significant resistance force to the passage of an indexed position. It is when he perceives the maximum value that the user stops his rotation or identifies a command position.
- One of the aims of the present invention is to improve the haptic feeling of the indexing so that it gives the illusion to the user to manipulate a conventional mechanical button, especially when the user manipulates the button after a period of time. immobilization, out of an indexed position.
- the present invention relates to a control interface to haptic feedback for a motor vehicle comprising:
- a magneto-rheological fluid module comprising a movable element, a magnetorheological fluid in contact with the movable element and a unit for applying a magnetic field configured to apply a magnetic field to the magnetorheological fluid and to modify the intensity of the magnetic field applied in order to generate a haptic feedback to the user displacing the mobile element by modifying the magnetic field applied to the magnetorheological fluid, and
- a processing unit connected to the unit for applying a magnetic field, configured to drive the unit for applying a magnetic field in order to index at least one position of the mobile element by generating a force braking to the moving element according to a programmed effort pattern
- a stop sensor for detecting a stopping position of the movable member
- the processing unit is connected to the stop sensor and configured to shift the programmed effort pattern relative to the stopping position of the movable element.
- the user moves the movable element again, he can for example perceive a force pattern corresponding to exiting an indexed position, as if he had stopped in a stable position indexed and had remained in this stable position or as if the movable element had itself reached the stable indexing position following or preceding an unstable stop position.
- This reinitialization of the programmed effort pattern makes it possible in particular for the user not to perceive intermediate forces, other than an indexed position, such as relating to the remainder to be traveled of a programmed effort reason interrupted before its complete execution.
- the offset of the haptic pattern is all the more interesting that the programmed effort pattern is hard, as it may be the case for example for a rotary element whose indexing has twenty notches on a rotation of 360 ° . The feeling thus approaches that of a mechanical indexing having stable positions indexing positions.
- the offset of the programmed effort pattern as a function of the stopping position of the movable element makes it possible to improve the coherence between the haptic feeling and the display if appropriate. Indeed, by simulating the tilting of the mobile element in indexed position, the feeling of indexing becomes consistent with the display for which a graphic element can only be selected / modified, or not. Indeed, an indexed position generally corresponds to a discrete state for a list or for a value (even very small). In the opposite case, the position is not generally notched.

- the programmed effort pattern is shifted so that the stop position coincides with the previous indexed position
- the processing unit is configured to shift the programmed effort pattern according to a kinematic parameter which precedes the stopping of the movable element
- a moving speed of the movable element less than 15 ° / s is a stop
- the stop sensor comprises a position sensor and / or a speed and / or contact and / or force sensor
- the mobile element is rotatable
- control interface comprises a display device for displaying at least one command to the user and the processing unit is configured to control the scrolling of the display of successive commands on the display device and / or to change the value of a parameter, such as a choice of an index in a list, sound volume, temperature or control of the gearbox, displayed on the display device.
- a parameter such as a choice of an index in a list, sound volume, temperature or control of the gearbox
- the subject of the invention is also a method of controlling an interface of control as described above, characterized in that indexes at least one position by generating a braking force to the rotating element according to a programmed effort pattern and shifts the programmed effort pattern relative to a position d stopping of the movable element, when the stopping of the movable element is detected.
- the programmed force pattern is shifted when the stopping position is different from an indexed position
- the effort pattern programmed is shifted so that the stop position coincides with an indexed position
- the effort pattern programmed is shifted so that the position of stop coincides with the next indexed position
