Method for generating a haptic feedback on a vehicle part
The proposed solution in particular relates to a method for generating a haptic feedback on a vehicle part including an operating element that is accessible for a user for manual actuation, and in response to an electronically detected actuation of the operating element, a feedback haptically perceptible for the user is generated in that the vehicle part and the operating element is adjusted back and forth in a power-operated way or is put into vibration.
1 . An apparatus, comprising:
an electromotive drive configured to adjust a vehicle window;
an electronic control unit;
an operating element on the vehicle window accessible for a user for manual actuation; and provided to electronically control a door function on the vehicle other than adjustment of the vehicle window from outside the vehicle; and
wherein, in response to an electronically detected manual actuation of the operating element a feedback haptically perceptible for the user is generated in that the vehicle window including the operating element is adjusted back and forth by the electromotive drive, wherein the electronic control unit is configured, for the back and forth adjustment of the vehicle window and in order to generate the haptically perceptible feedback on the vehicle window, to actuate the electromotive drive to rotate for less than 10 ms in a first direction of rotation and to rotate for less than 10 ms in an opposite second direction of rotation.
2 . The apparatus of claim 1 , wherein the apparatus includes a power-operated back-and-forth adjustment of the vehicle window that is effected in response to an individual electronic actuation of the operating element.
3 . The apparatus of claim 1 , wherein the apparatus includes a power-operated back-and-forth adjustment of the vehicle window that is effected along an adjustment axis in mutually opposite adjustment directions along which the vehicle window can be adjusted in a power-operated way independently of an actuation of the operating element.
4 . The apparatus of claim 1 , wherein a duration of the actuation of the drive is dependent on an adjustment position of the vehicle window.
5 . The apparatus of claim 4 , wherein in response to an adjustment position of the vehicle window, the duration of the actuation of the drive for a rotation in the one direction of rotation is greater or less than the duration of the actuation of the drive for a rotation in the other direction of rotation.
6 . The apparatus of claim 1 , wherein and the electromotive drive is controlled via a pulse-width-modulated signal; and wherein, in response to the power-operated back-and-forth adjustment of the vehicle window, the electromotive drive is actuated for less than 30 periods via two half-pulses for rotations in two mutually opposite directions of rotation.
7 . The apparatus of claim 1 , wherein the electromotive drive is configured to provide a first haptic feedback via a first signal course for the back and forth adjustment of the vehicle window and to provide a second haptic feedback via, at least one second signal course differing from the first signal course.
8 . An apparatus, comprising:
a speaker for outputting sound not audible for a human ear;
an electronic control unit; and
an operating element on a vehicle door accessible for a user for manual actuation and provided to electronically control a function on the vehicle other than an adjustment of the vehicle window from outside the vehicle,
wherein the electronic unit is configured, in response to an electronically detected manual actuation of the operating element, to generate a feedback haptically perceptible for the user on the vehicle door by putting the vehicle door into vibration via operating the speaker with a frequency not audible for the human ear of less than 20 Hz.
9 . The apparatus of claim 8 , wherein the apparatus includes the speaker and the speaker is mechanically coupled to the vehicle door in order to put the vehicle door into vibration.
10 . The apparatus of claim 1 , wherein the operating element is provided a window pane or on a door outer skin of the operating element is configured to electronically detect an actuation of a door handle of the vehicle door.
11 . An apparatus, comprising:
an electronic control unit;
a vehicle door including a door outer skin, and a window pane; and
an operating element on the window pane or the door outer skin, the operating element being accessible for a user for manual actuation and provided to electronically control a function other than an adjustment of the window pane from outside the vehicle,
wherein the electronic unit is configured, in response to an electronically detected manual actuation of the operating element, to generate a feedback haptically perceptible for the user on the window pane by putting the window pane into vibration or adjusting the window back and forth, the haptically perceptible feedback by adjusting the window back and forth being different to an adjustment of the window pane for clearing or closing a window opening in the vehicle door.
12 . The apparatus of claim 11 , wherein the vehicle door further includes a window lifter with a carrier for adjusting the window pane, and wherein the electronic unit is configured to generate the feedback haptically perceptible for the user on the window by actuating at least one piezo element on the carrier to put the window pane into vibration.
13 . The apparatus of claim 12 , wherein at least one piezo element is arranged between a portion of the carrier and a portion of the window pane.
