Head-Up Display, Component Description - GF54.30-P-6140LF

Model 217, 222 

with code 463 (Head-up display) 

Shown model 222.0 

Location 

The heads-up display is located in a recess in the instrument panel and it is attached to the cockpit cross member.

Tasks 

The head-up display projects driver-relevant information (e.g. speed, navigation information etc.) onto the windshield and into the field of view of the driver. Only information that is redundant to the instrument cluster (A1) is shown.

The heads-up display is responsible for the following:

• Reading in of sensors and signals 
• Evaluation of input factors 
• Output of signals 

Reading in of sensors and signals 

The heads-up display reads in the input factors over the following connections:

• High-speed video link (HSVL) 
• User interface CAN (CAN HMI) 

High-speed video link 

The instrument cluster processes visual information to be displayed in the head-up display and transmits this over an HSVL line to the head-up display.

User interface CAN 

The signals are read in by the head-up display via the user interface CAN. The functions that use these signals are described in the individual function descriptions (see the appropriate block diagram or function schematic).

Evaluation of input factors 

The input factors that have been read in are evaluated by the integrated microprocessor and the relevant components are then actuated.

Output of signals 

The signals are output over the following connection:

• User interface CAN 

User interface CAN 

The signals are sent by the heads-up display over the user interface CAN. The functions that use these signals are described in the individual function descriptions (see the appropriate block diagram or function schematic).
