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 Traffic Jam Assistant is available for speeds up to approximately 43 mph
(70 km/h), the Active

Collision Avoidance is
also interlinked.
Hands-off-Detection

both hands on the steering
wheel when the Active Lane Keeping Assistant and Traffic Jam Assistant are

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.
