The invention relates to a haptic feedback device (1) for a motor vehicle, comprising; a mobile part (2) comprising a capacitive interface (6) comprising; at least one capacitive sensor (9) for detecting at least one contact of a user on the surface of the capacitive interface, and a contact plate (13) arranged on the capacitive sensor (9), and a fixed part (3) intended to be fixed to the motor vehicle, characterised in that it further comprises; at least one contactless movement sensor (15) arranged between the fixed part (3) and the mobile part (2), in order to measure a movement of the mobile part (2) with respect to the fixed part (3), at least one vibrating actuator (7) suspended at the capacitive interface (6) to cause the capacitive interface (6) to vibrate in response to a measured movement of the mobile part (2) with respect to the fixed part (3), and at least one damping member (8) interposed between the capacitive interface (6) and the fixed part (3), in order to connect the mobile part (2) to the fixed part (3) and to enable a relative movement between the mobile part (2) and the fixed part (3), said relative movement comprising the vibration created by the vibrating actuator (7) and the movement of the mobile part (2) with respect to the fixed part (3) that is intended to be measured. The invention also relates to a method for control of haptic feedback.
