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 control device for a motor vehicle, which includes: a touch-sensitive surface () including a contact sensor capable of measuring a pressing pressure on the touch-sensitive surface () during a predetermined time (dt; dt, dt), and a haptic feedback module () configured such as to generate a haptic feedback in response to a contact of the touch-sensitive surface (), characterised in that the haptic feedback module () is configured such as to determine the profile of the haptic feedback to be generated in accordance with the variation in the pressing pressure measured on the touch-sensitive surface () during the predetermined time (dt; dt, dt).

Control device for motor vehicle and control method

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.

Device and method for haptic feedback for automotive vehicle

A control device for automotive vehicle is disclosed. The control device includes a tactile surface to detect a contact of a finger of a user, a haptic feedback module configured to vibrate the tactile surface, and a drive unit configured to drive the haptic feedback module so as to generate a haptic feedback in response to a press on the tactile surface. The haptic feedback is composed of at least two individual haptic patterns which exhibit an identical trend and are generated successively, with a period of no haptic feedback intercalated between two successive individual haptic patterns, the energy of the individual haptic patterns varying with their repetition. A method of control of such a device is also disclosed.

Device and method for haptic touch feedback in a vehicle

The invention relates to a method for controlling a control device for a motor vehicle which comprises measuring the variation in the pressure by a user pressing on a touch-sensitive surface () and generating a haptic feedback, characterised in that the haptic feedback comprises at least one vibratory feedback when the variation in the pressing pressure (dp, dp, dp) over a predetermined time (dt, dt) is within a predefined range, and in that the haptic feedback is replaced with a replacement acoustic feedback when the variation in the pressing pressure (dp, dp, dp) over the predetermined time (dt, dt) leaves the predefined range.
