1. A method for commanding a control device for an automotive vehicle, comprising:
- measuring the pressure variation of a press of a user on a touch surface of the control device; and
generating a sensory stimulus in response to the measurement,wherein the press pressure variation is an average value of the press pressure over a predetermined duration,wherein the sensory stimulus includes at least one vibratory stimulus when the variation in the press pressure over the predetermined duration is comprised in a predefined range,wherein the sensory stimulus is replaced with a substitutional audio stimulus when the variation in the press pressure over the predetermined duration departs from the predefined range,wherein the sensory stimulus includes a vibratory stimulus and an associated audio stimulus when the variation in the press pressure over a predetermined duration is comprised in a predefined range and the sensory stimulus including a vibratory stimulus and an associated audio stimulus is replaced with a substitutional audio stimulus when the variation in the press pressure over the predetermined duration departs from the predefined range, andwherein the frequency range of the substitutional audio stimulus is the same as the frequency range of the vibratory stimulus.

Abstract
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 (2) and generating a haptic feedback, characterised in that the haptic feedback comprises at least one vibratory feedback when the variation in the pressing pressure (dp1, dp2, dp2′) over a predetermined time (dt1, dt2) 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 (dp1, dp2, dp2′) over the predetermined time (dt1, dt2) leaves the predefined range.
