BMW 3: Emergency Stop Assistant

Concept

If the driver is no longer fit to drive, the system helps to safely bring the vehicle to a standstill.

General information

The emergency stop function is not triggered automatically. The emergency stop function can only be triggered manually by the occupants.

When the system is activated, the vehicle is brought to a standstill in its own lane by use of lane guidance.

Depending on the equipment version and national market version, the system includes a lane change function.

With lane change function: On motorways or motorway- like roads, the system steers the vehicle to the side of the road or shoulder where possible.

On other roads or under high traffic conditions, the vehicle is brought to a standstill on the actual road.
