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.
