AbstractA display incorporates analog components (such as a pointer) and digital components (such as an LCD display) which cooperate to convey information. The digital display may be dynamically reconfigurable and may selectively display information relating to any number of vehicle parameters. The digital display may also be configurable to display information without use of the analog components.
Hybrid Vehicular Display
A display incorporates analog components (such as a pointer) and digital components (such as an LCD display) which cooperate to convey information. The digital display may be dynamically reconfigurable and may selectively display information relating to any number of vehicle parameters. The digital display may also be configurable to display information without use of the analog components.
Description of the Innovation
Typical instrument displays for automobiles use analog methods of displaying data. Particularly, most vehicles use pointers that are controlled by stepper motors. Behind the pointers are pre-selected graphic appliqués with markings (e.g. speed in 5 mph increments) to which the pointers point to display information. Also, such displays of information typically use tell-tales which shine light through a graphic to alert the driver to some event (such as low fuel).
Some vehicles have used digital displays to provide a driver with information. This information may include odometer readings, trip computer readings, compass readings, and has, in the past, included speedometer readings.
Digital displays enable ease of use and the ability to configure and change the type of information used. Analog displays allow a more traditional feel to an instrument cluster with which people may tend to be more comfortable. Some vehicles may use analog components to display information such as speed and digital components to display information such as odometer readings.
A system that could advantageously combine the advantages of each of these systems would be desirable.
The attached figures illustrate exemplary instrument clusters combining analog and digital components to form a hybrid display. These instrument clusters use analog pointers placed over reconfigurable digital displays.
The type of information displayed on the display can be changed (speed, fuel level, rpm, engine heat, etc.) and the pointers can be controlled according to the type of information being displayed. The change may be controlled by a user, by a manufacturer, or based on predetermined events.
The display may also be configured to adjust the manner in which the parameters are displayed (size, color, contrast, etc.) based on predetermined events and/or based on user preferences. Using a digital display may also allow warnings to be animated to allow them to better attract a user's attention.
If the display is set to display information for which the pointers are not needed, the pointers may be placed in a stowed position in which they do not block the display. Information for which the pointers are not needed may be selected by a designer to include outside temperature, navigation system data, compass data, entertainment data, and other types of data.
