Abstract
The invention relates to a control device for a motor vehicle, which includes: a touch-sensitive surface (2) including a contact sensor capable of measuring a pressing pressure on the touch-sensitive surface (2) during a predetermined time (dt; dt1, dt2), and a haptic feedback module (4) configured such as to generate a haptic feedback in response to a contact of the touch-sensitive surface (2), characterised in that the haptic feedback module (4) 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 (2) during the predetermined time (dt; dt1, dt2).
Claims20
A control device for an automotive vehicle, comprising:
- a touch surface including a contact sensor that measures a press pressure on the touch surface during a predetermined time duration;
- and
- a sensory stimulus module that generates a sensory stimulus in response to a contact with the touch surface,
- wherein:
- the sensory stimulus module determines a profile of the sensory stimulus to be generated depending on the press pressure variation measured on the touch surface during the predetermined time duration,
- the predetermined time duration is a combination of, at least, a first predetermined time length and a second predetermined time length, which are distinct and different from one another,
- the first predetermined time length indicates that the press pressure variation becomes detectable on the touch surface,
- the second predetermined time length indicates that the press pressure variation ceases to increase and subsequently starts decreasing on the touch surface,
- the first and second predetermined time lengths are not contiguous along a time domain, and
- wherein the predetermined time duration during which the press pressure variation is measured is shorter than 30 milliseconds.
A method for commanding the control device for an automotive vehicle, the method including:
- measuring a press pressure on a touch surface during a predetermined time duration,
- generating a sensory stimulus in response to a contact with the touch surface,
- wherein a profile of the generated sensory stimulus is determined depending on the press pressure variation measured on the touch surface during the predetermined time duration,
- wherein the predetermined time duration is a combination of, at least, a first predetermined time length and a second predetermined time length, which are distinct and different from one another,
- wherein the first predetermined time length indicates that the press pressure variation becomes detectable on the touch surface,
- wherein the second predetermined time length indicates that the press pressure variation ceases to increase and subsequently starts decreasing on the touch surface,
- wherein the first and second predetermined time lengths are not contiguous along a time domain, and
- wherein the predetermined time duration during which the press pressure variation is measured is shorter than 30 milliseconds.
A control device for an automotive vehicle, comprising:
- a touch surface including a contact sensor that measures a press pressure on the touch surface during a predetermined time duration;
- and
- a sensory stimulus module that generates a sensory stimulus in response to a contact with the touch surface,
- wherein:
- the sensory stimulus module determines a profile of the sensory stimulus to be generated depending on the press pressure variation measured on the touch surface during the predetermined time duration,
- the predetermined time duration is a combination of, at least, a first predetermined time length and a second predetermined time length, which are distinct and different from one another,
- an increase in the press pressure is measured over a first portion of the predetermined time duration and a press sensory stimulus is generated with the profile which depends on the variation in the measured press pressure,
- then, when the measured press pressure ceases to increase and decreases, a decrease in the press pressure is measured over the predetermined time duration and a release sensory stimulus is generated with the profile which depends on the variation in the measured press pressure, and
- a delay time duration for which no sensory stimulus is generated after the generation of the press sensory stimulus.
