F01 KAFAS
Multifunction Video Camera
With the F01/F02, the customer is able to choose from a comprehensive range of
optional driver assistance systems.
The individual systems and function units are becoming ever more densely networked
as a result of the shared use of components and signals in some areas.
Depending on the combination of the available options installed, the functions in the
F01/F02 are implemented as camera-based systems, both sharing the same camera
and the one control unit, the KAFAS control unit.
KAFAS is the Camera Assisted Driver Assistance System.
KAFAS is used for the following combined functions:
• Lane departure warning
• High-beam assistant.
Introduction

F01 KAFAS
FLA (high beam assistant) is part of the ZDA Driver Assistance Package option and will
not be available separately on the F01/F02.
The ZDA Driver Assistance Package option includes the following:
• High-beam Assistant
• Lane Departure Warning
• Active Blind Spot Detection
The vehicle comes fitted with the KAFAS control unit and camera. The high-beam assis-
tant option shares the KAFAS camera and the KAFAS control unit with the lane departure
warning system.

The image data recorded by the video camera are transmitted to the KAFAS control unit
along an LVDS data line. The video camera and the control unit are the components that
are fundamental to the lane departure warning’s range of functions.
