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-implantation 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.

• a touch surface for detecting a touch of a user's finger and moving the finger on the touch surface
• a haptic and / or audible feedback module configured to vibrate the tactile surface and / or to generate a sound feedback to the user, in response to contact of the tactile surface
• control unit configured to control the haptic and / or sound feedback module, in order to generate a haptic and / or audible return pattern when a movement of the finger is detected on a border separating two zones touch surface.
• Border separating two zones means a boundary or limitation predefined on the touch surface via for example the computer program or software loaded into the control unit. It is therefore a software-defined boundary and not a physical boundary or identified by markings. One can thus simulate through haptic feedback and / or sound, a physical boundary or a limitation between two areas while the touch surface is devoid and generally smooth.
• control device taken alone or in combination,
• the touch surface comprises at least a first zone delimited by a closed surface, and at least a second zone surrounding said first zone.
• a first haptic and / or sound return is generated when a movement of the finger entering the first zone delimited by a closed surface is detected and a second haptic and / or sound return is generated when a displacement of the finger exiting in said first zone is detected.
• the second haptic and / or sound return is distinct from the first haptic and / or sound return
• control unit controls a function when a contact is detected in the area behind the border
• a parameter of the sound return is chosen from the intensity of the volume, phase, frequency, duration and / or a parameter of the haptic feedback is chosen from the intensity of the acceleration, frequency, amplitude, duration, phase.

• 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 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.
