HUD Image Layout
The HUD background color is transparent.
Symbols (such as e.g. warning symbols) are specified by the individual control units. This color specification is adopted for the display in the HUD.
Two dimensional symbols are used for optimum visibility and legibility.
The colors are:
- Orange as the standard color
- Red or yellow for warning messages
- Green for the set speed
The 4 colors are generated by the layout of the LED's and the corresponding actuation of the LED's by the electronic circuitry of the Head-up display.
The size of the virtual image display range is approximately. 20 x 10 cm (width x height). To make the contents of the display easier to read, the display range is divided into an upper section and a lower section. Navigation instructions and Check-Control messages are displayed in the upper section. Speed-related information is displayed in the lower section.
The signals used to generate the image in the head-up display are input from the corresponding control units, e.g. multi-audio system controller (M-ASK) via the K-CAN and MOST data buses to the electronic circuitry in the head-up display. The electronic circuitry evaluates the incoming signals and forwards the prepared image information to the components in the head-up display.
