Abstract

A method controls a transmission in a motor vehicle. The method involves displaying transmission information on a primary display, determining when a hand is approaching a gear selector, and initiating a display of, and then displaying, gear selection information on a secondary display when the hand is approaching the gear selector, before the hand touches the gear selector, the secondary display being a multi-use changeable display that, at different times, displays information for different systems of the motor vehicle. The method may therefore provide the information to the driver when it is needed, before the gear is shifted.

First claim

What is claimed is:

1. A method for controlling a transmission in a motor vehicle, comprising:
displaying transmission information on a primary display;
determining when a hand is approaching a gear selector; and
initiating a display of, and then displaying, gear selection information on a secondary display when the hand is approaching the gear selector, before the hand touches the gear selector, the secondary display being a multi-use changeable display that, at different times, displays information for different systems of the motor vehicle.

2. The method according to claim 1 , wherein a time-of-flight camera determines when the hand is approaching the gear selector.

3. The method according to claim 1 , wherein the secondary display is an instrument cluster display or a heads-up display projected onto a windshield of the motor vehicle.

4. The method according to claim 1 , wherein the secondary display is a heads-up display projected onto a windshield of the motor vehicle.

5. The method as claimed in claim 1 , wherein
the transmission information comprises engine speed and vehicle speed,
the gear selection information comprises a currently engaged gear,
the primary display is a first portion of an instrument cluster display,
the secondary display is a second portion of the instrument cluster display or a heads-up display projected onto a windshield of the motor vehicle, and
the transmission information is displayed before the hand is approaching the gear selector and maintained after the gear is changed.

6. The method according to claim 1 , wherein if it is determined that only a passenger's hand is approaching the gear selector, the gear selection information is not displayed on the secondary display.

7. The method according to claim 6 , wherein
a time-of-flight camera is used to determine when the hand is approaching the gear selector, and
the time-of-flight camera is used to determine whether a driver's hand or the passenger's hand is approaching the gear selector.

8. The method according to claim 1 , wherein the gear selection information is selected from the group consisting of a currently engaged gear, engine speed and a new gear suggestion.

9. The method according to claim 1 , wherein the gear selection information remains displayed in the secondary display while the hand touches the gear selector.

10. The method according to claim 9 , wherein the gear selection information is removed from the secondary display as soon as the hand is removed from the gear selector.

11. The method according to claim 9 , wherein, when the hand is removed from the gear selector, the gear selection information remains displayed on the secondary display for a time shorter than a time period that would be required for a driver to read the gear selection information on the secondary display if the gear selection information first appeared on the secondary display only after the gear selector was moved.

12. The method according to claim 1 , wherein the gear selection information is removed from the secondary display as soon as a driver shifts gears.

13. The method according to claim 1 , wherein
the gear selection information is displayed for a display time that depends on how fast the motor vehicle is currently travelling, such that at higher speeds, the display time is shortened.

14. The method according to claim 13 , wherein the display time is shortened by at least one of:
requiring that the hand be closer to the gear selector before initiating the display of the gear selection information, and
reducing the display time for which the gear selection information remains displayed.

15. The method according to claim 1 , wherein
the secondary display displays navigation information for a navigation system of the motor vehicle, and
at least a part of the navigation information is excluded from the secondary display when displaying gear selection information in the secondary display.

16. A motor vehicle comprising:
a transmission having a gear selector;
a primary display to display transmission information;
a secondary display to display gear selection information, the secondary display being a multi-use changeable display that, at different times, displays information for different systems of the motor vehicle;
a gesture recognition device to recognize when a hand is approaching the gear selector; and
a controller to initiate a display of, and then display, gear selection information on the secondary display while the hand is approaching the gear selector, before the hand touches the gear selector.
