Abstract

A human-machine interface for a motor vehicle, comprising: —a command device (1) comprising at least one sensor configured to detect a command without contact by the user, and —a haptic feedback device (2) to control the consideration of said command, characterized in that —the haptic feedback device engages with a component (3) in the motor vehicle passenger compartment, said component being distinct from the command device, —said component being intended to come into contact with a part of in the body (5) of the user in order to perceive the haptic feedback signal.

Claims

1. A human-machine interface for a motor vehicle comprising:

a control device comprising at least one sensor configured to detect a contactless command from a user; and

a haptic feedback device for monitoring the recognition of said command,

wherein the haptic feedback device cooperates with an equipment item of the interior of the motor vehicle, said equipment item being distinct from the control device, and

wherein said equipment item is intended to come into contact with a part of the body of the user in order to perceive the haptic feedback signal.

2. The human-machine interface as claimed in claim 1, wherein the haptic feedback device comprises a vibrating device configured to communicate one or more vibrations to the equipment item associated with the feedback device, the intensity of the vibrations being sufficient to be felt by said part of the body of the user.

3. The human-machine interface as claimed in claim 1, wherein the sensor comprises an infrared system and/or a capacitive system and/or a camera.

4. The human-machine interface as claimed in claim 1, wherein the control device is capable of canceling or of triggering a commanded function by virtue of the emission of an activation signal.

5. The human-machine interface as claimed in claim 1, configured such that the time between the activation of the control device and the emission of the feedback signal by the feedback device is less than or equal to 100 ms, notably less than or equal to 90 ms.

6. The human-machine interface as claimed in claim 1, further comprising a programming device configured for the user to program the intensity and the duration of the feedback signal emitted by the feedback device and the time between the command and the emission of the feedback signal by the feedback device.

7. The human-machine interface as claimed in claim 1, wherein the feedback device is associated with a hand rest of the motor vehicle.

8. The human-machine interface as claimed in claim 1, wherein the feedback device is associated with the steering wheel of the motor vehicle.

9. The human-machine interface as claimed in claim 1, wherein the feedback device is associated with the driver'"'"'s seat of the motor vehicle.

10. The human-machine interface as claimed in claim 1, wherein the feedback device is associated with the armrest of the motor vehicle.
