The invention relates to a control device for a motor vehicle, comprising: a tactile surface () for detecting the contact of the finger of a user and the movement of the finger on the tactile surface; and a haptic and/or acoustic feedback module () designed to make the tactile surface () vibrate and/or to generate an acoustic feedback for the user, in response to contact on the tactile surface (); characterised in that it comprises a management unit () designed to manage the haptic feedback and/or acoustic feedback module () in order to generate a haptic and/or acoustic feedback of which at least one parameter of the haptic and/or acoustic feedback varies with the direction of movement of the finger on the tactile surface (). The invention also relates to a control method.

Control device for a motor vehicle

The invention relates to a motor vehicle control device comprising: a touch surface () for detecting contact from a finger of a user and locating the contact on the touch surface (); and a haptic and/or audio feedback module () configured such as to cause the touch surface () to vibrate and/or such as to generate audio feedback to the user, in response to contact with the touch surface (), characterized in that said motor vehicle control device comprises a control unit () configured such as to control the haptic and/or audio feedback module () such that the value of at least one parameter of the haptic and/or audio feedback depends on the distance (D) between the location (P) of the finger of the user and a target area (Zc) for controlling the touch surface (). The invention also relates to a control method.

Device and method for controlling a motor vehicle

The invention relates to a haptic-feedback tactile interface module, including: a tactile surface capable of detecting at least one characteristic of a pressure exerted by a user; at least one haptic-feedback actuator configured to transmit haptic feedback to the tactile surface; and a processing and control unit connected to the tactile surface and to said at least one actuator. The processing and control unit is configured so as to activate the haptic-feedback actuator in a first time window (T) so as to induce at least one mechanical wave propagating over the tactile surface, capable of being perceived as haptic feedback, and in a second time window (T) so as to generate at least one mechanical pulse (---) which is phase-shifted relative to the mechanical wave in order to dampen said mechanical wave.

Tactile interface module and method for generating haptic feedback

The invention relates to an actuator () which comprises: a frame () intended for being in contact with the tactile interface via a contact wall () so as to transmit haptic feedback to the tactile surface; a stator () connected to the frame (); a movable core () connected via at least one resilient element to the frame () and intended for being moved by the stator () so as to generate the haptic feedback; an electromagnet () and at least one permanent magnet (), one of which is supported by the stator and the other by the movable core (). The actuator () also comprises a shock absorber () arranged between the movable core () and the contact wall (), and said resilient element is sized so that, when the electromagnet is not powered, the movable core () applies a bearing force towards the contact wall () and, when the electromagnet is powered according to a predetermined polarisation, the movable core () moves away from the contact wall ().

Actuator of a tactile interface module, tactile interface module and method for generating haptic feedback

A control device for an automotive vehicle has a touch surface with a plate bearing a contact sensor that detects contact of a finger of a user, a haptic feedback module that vibrates the touch surface, which includes actuators positioned below the touch surface and linked to the plate of the touch surface, and a driver unit configured to drive the haptic feedback module to generate haptic feedback in response to a press on the touch surface. The haptic feedback is composed of a vibratory signal produced by control signals including one or more succession of pulses sent to the actuators, wherein each of the plurality of control signals generates one individual haptic pattern, a repetition of at least two identical individual haptic patterns, generated successively, and a period with no haptic feedback between two successive individual haptic patterns. A method of control of such a device is also disclosed.
