BMW 5 Series: Functional principle
Depending on the speed, the system is guided by the lane edges or vehicles
driving ahead.
The position of the lane edges and the vehicle driving ahead is determined with
the help of five radar
sensors and the KAFAS stereo camera.

The system has two subfunctions: the Traffic Jam Assistant (second
generation) and the Active Lane
Keeping Assistant.
The Traffic Jam Assistant is available for speeds up to approximately 43 mph
(70 km/h), the Active
Lane Keeping Assistant from approximately 43 mph (70 km/h) to approximately 130
mph (210 km/h).
The table below shows an overview of the differences between the two
subfunctions:
If the Traffic Jam and Active Lane Keeping Assistants are activated, the Side
Collision Avoidance is
also interlinked.
Hands-off-Detection
To ensure the driver is alert and able to react, he is urged to always have
both hands on the steering
wheel when the Active Lane Keeping Assistant and Traffic Jam Assistant are
activated (established in
the German road traffic regulations). If the driver takes both hands off the
steering wheel rim, control is
stopped after a few seconds during active control and the driver is requested to
take over steering.
Additional information about Hands-off-Detection may be found in the "G12 Driver
Assistance
Systems" reference manual.
