GF54.30-P-6200LE Night View Assist Control Unit, Component Description

GF54.30-P-6200LE Night View Assist Control Unit, Component Description
- with CODE (610) Night View Assist

Component Identification:

Location
The Night View Assist control unit is located on the left on the A-pillar behind the paneling in the driver footwell.

Task
The Night View Assist control unit performs the following tasks:
^ Reading in of sensors, pickups and signals
^ Evaluation of input factors
^ Output of signals
^ Actuation of components

For vehicles up to 31.5.09, the Night View Assist control unit is a subscriber to the vehicle dynamics CAN (CAN H). For vehicles as of 1.6.09, the Night View Assist control unit is a subscriber to the chassis CAN (CAN E).

Reading in of sensors, pickups and signals
The input factors are read in via the following connections:
^ Low voltage differential signal (LVDS)
^ Vehicle dynamics CAN (up to 31.5.09)
^ Chassis CAN (as of 1.6.09)

LVDS
The Night View Assist control unit reads in the pictures taken by the Night View Assist camera (B84/2) over the digital video interface (LVDS connection).

Vehicle dynamics CAN (up to 31.5.09)
The Night View Assist control unit reads in the signals via the vehicle dynamics CAN.
The functions resulting therefrom are described in the corresponding function descriptions (see block diagram or function schematic).

Chassis CAN (as of 1.6.09)
The Night View Assist control unit reads in the signals via the chassis CAN.
The functions resulting therefrom are described in the corresponding function descriptions (see block diagram or function schematic).

The following information is read in and processed:
- Rotary light switch status (S1) and Night View Assist button status (S1s9)
- Rain/light sensor data (B38/2)
- Low beams activation status
- Wheel speeds, vehicle speed
- Light source identification by the multifunction camera (A40/11) (as of 1.6.09)
- Vehicle dynamics (as of 1.6.09)
- Status of reverse gear

Evaluation of input factors
The integrated microprocessor evaluates the information read in. The pictures taken by the Night View Assist camera are processed accordingly. The information read in is also used for fault detection and system diagnosis.

Output of signals
The Night View Assist control unit transmits the processed picture data over the digital video interface (LVDS connection) to the instrument cluster.
Camera control is performed by the Night View Assist control unit via the control channel of the digital video interface.

Actuation of components
The actuation of the components takes place via the following connections:
^ Vehicle dynamics CAN (up to 31.5.09)
^ Chassis CAN (as of 1.6.09)
