Abstract
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.
