Abstract

A reconfigurable vehicle user interface system is presented. A vehicle user interface has a touch sensitive input devices such as touchpads and a touch screen that have specific function commands mapped to them. A user can select which function commands are mapped to which portions of the touch screen. This allows a user to customize the steering wheel function commands.

Claims

1. A reconfigurable vehicle user interface system comprising:

a steering wheel;

a touch screen disposed along an outer surface of the steering wheel that generates a signal upon sensing user contact with a touch-sensitive surface of the touch screen, wherein the signal is dependent on location of the user contact;

a controller that receives the signal generated by the touch screen and determines a function command from the signal based on the location of the user contact;

a plurality of input shortcuts displayed on the touch screen, each user input shortcut has a mapping to a specific function command, wherein each user input shortcut displayed on the touch screen indicates to the user the specific function command that is mapped to the user input shortcut; and

a touch screen reconfiguration module that receives a user configuration specified by the user indicating a configuration of the plurality of user input shortcuts and displays the plurality of user input shortcuts according to the user configuration, wherein the user configuration includes an amount of user input shortcuts to be displayed, locations of each of the user input shortcuts, sizes of each of the user input shortcuts, and the mapping of the location to function command of each of the user input shortcuts,

the touch screen reconfiguration module and the touch screen defining a plurality of different user selectable screen layouts for configuring the wheel-mounted touch screen, each layout characterized by a predefined number of discrete areas each adapted to accommodate one shortcut,

the touch screen reconfiguration module being further adapted to allow the user to select among the plurality of different screen layouts by specifying the number of shortcuts desired to be displayed and by further selecting which of the discrete areas of a selected layout shall contain a shortcut.

2. The system of claim 1 further comprising a storage module that stores a plurality of usable user input shortcuts, wherein the user selects the plurality of user input shortcuts from the plurality of usable user input shortcuts.

3. The system of claim 2 further comprising a touchpad, wherein the plurality of the user input shortcuts are flexibly displayed on the touchpad.

4. The system of claim 2 further comprising a user configuration database storing a plurality of user configurations for a plurality of users, wherein the touch screen configuration module displays the plurality of user interface shortcuts according to the user of the plurality of users that is driving the vehicle.

5. The system of claim 1 further comprising a touchpad disposed on the surface of the steering wheel for entering user input, wherein the user selects a function command using the touch screen and manipulates a setting of a device corresponding to the function command using the touchpad.

6. The system of claim 1 further comprising a display unit that displays to the user device settings after the user contacts the user input function associated with the device.

7. The system of claim 1 further comprising an inertial sensor that generates a signal indicating an amount of change in motion of the vehicle and communicates the signal to the controller, wherein the controller deactivates the vehicle user interface system when the signal exceeds a predetermined threshold.

8. The system of claim 2 wherein the controller receives user input shortcuts for a new device and stores said user input shortcuts in the storage module thereby integrating the new device with the vehicle user interface system.

9. The system of claim 1 wherein the touch screen provides a user with at least one of haptic, tactile, visual, or audio response when contacted by the user.

10. A reconfigurable vehicle user interface system comprising:

a steering wheel;

a touchpad disposed on the steering wheel;

a display for displaying a user input shortcut; and

a controller for controlling displaying the user input shortcut,

wherein the controller changes displaying the user input shortcut according to an operation on the touchpad,

the controller having a touch screen reconfiguration module,

the touch screen reconfiguration module and the touch screen defining a plurality of different user selectable screen layouts for configuring the wheel-mounted touch screen, each layout characterized by a predefined number of discrete areas each adapted to accommodate one shortcut,

the touch screen reconfiguration module being further adapted to allow the user to select among the plurality of different screen layouts by specifying the number of shortcuts desired to be displayed and by further selecting which of the discrete areas of a selected layout shall contain a shortcut.

11. The system of claim 10 wherein the touchpad is disposed on two sides, right and left, of the steering wheel, the user input shortcut is displayed on at least two sides, right and left, of the display, the controller changes a setting of the right user input shortcut according to an operation on the right touchpad, and the controller changes a setting of the left user input shortcut according to an operation on the left touchpad.
