Definitions
- the present invention relates to a haptic feedback device for a motor vehicle, generating a haptic feedback to the user in response to a touch on a touch surface.
- touch-sensitive multifunction control interfaces are increasingly used to control electrical or electronic systems, such as an air conditioning system, an audio system or a navigation system.
- Such interfaces may be associated with a display screen and allow navigation in pull-down menus comprising various commands relating to the systems to be controlled.
- the haptic feedback is generally obtained by the action of a vibratory actuator fixed to the tactile surface and controlled by a control unit in order to vibrate the tactile surface in response to a contact.
- the haptic feedback may not be perceived on the entire surface. Indeed, the more the point of contact of the user with the touch surface is away from the actuator and the more the haptic feedback is attenuated.
- vibratory actuators can then be used to transmit a haptic feedback that can be felt on the entire touch surface. These actuators are controlled simultaneously. The larger the size of the touch surface, the more the number of actuators increases. For example, four vibratory actuators are provided to vibrate a nine inch touch surface and eight actuators to vibrate a fifteen inch touch surface.
- Another disadvantage is the difficulty of implementing the control synchronization of this plurality of actuators.
- Another solution is to substantially increase the size of the vibratory actuator.
- the larger the touch surface the larger the actuator.
- a large actuator makes it possible to increase the amplitude of the vibration of the tactile surface so that it can be felt even in areas far from the actuator.
- such an actuator increases the size of the system. Moreover, it is more expensive.
- An object of the present invention is to provide a haptic feedback device for tactile surfaces of relatively large size, having a moderate cost, a simple and compact architecture, easy to implement, can generate a haptic feedback of frank appearance that is felt well on the entire touch surface.
- the subject of the present invention is a haptic feedback device for a motor vehicle comprising a tactile surface intended to detect a contact of a user and at least one electrically operated vibratory actuator intended to vibrate the tactile surface, characterized in that it comprises at least one passive resonator arranged at a distance from the electrically controlled vibratory actuator and configured to vibrate due to the vibration of the touch surface generated by the electrically operated vibratory actuator.
- the passive resonator is an actuator having a resonant frequency of its own without power supply. This makes it possible to increase the amplitude of the vibration generated by the electrically operated vibratory actuator so that the haptic feedback can be felt on the entire tactile surface. In addition, it eliminates the problems of control synchronization.
- the haptic feedback device is thus simplified and compact.
- the haptic feedback device comprises a passive resonator and an electrically operated vibratory actuator disposed on a diagonal of the tactile surface

- the vibration of the passive resonator then makes it possible to amplify the haptic effect
- the haptic feedback device comprises a control unit connected to the electrically operated vibratory actuator and the passive resonator comprises an electrically controlled vibratory actuator not connected to the control unit.
- the vibratory actuators with electric control can therefore be identical. This facilitates assembly and assembly of the haptic feedback device.
- the haptic feedback device comprises a control unit connected to the electrically-controlled vibratory actuator and the passive resonator comprises an electrically-controlled vibratory actuator connected to the control unit, the control unit being configured to control the implementation of vibration of a single electrically operated vibratory actuator at a time, the vibratory actuator with unmanned electrical control forming the passive resonator.
