BMW 5 Series: Active Lane Keeping Assistant

The Active Lane Keeping Assistant with Side Collision Avoidance is part of the Active Driving Assistant Plus, optional equipment (OE 5AT).

By making corrective steering interventions, the system, already familiar from the G12 helps the driver to keep the vehicle in lane at speeds from approximately 43 mph (70 km/h) to approximately 130 mph (210 km/h) and to actively avoid potential side collisions. The system endeavors to orient the vehicle in its lane according to the situation and within the framework of the system limits.

The system consists of the following four subfunctions:

  • Side Collision Avoidance
  • Reduced Side Collision Avoidance
  • Lane Departure Warning
  • Blind Spot Detection

Side Collision Avoidance

The table below shows an overview of the functional characteristics of the "Side Collision Avoidance" subfunction:

The Reduced Side Collision Avoidance comes into play if it is not possible to adequately monitor the available space on the roadway or there is no available space on the roadway.

The Reduced Side Collision Avoidance is interlinked with the Active Lane Keeping Assistant and Traffic Jam Assistant functions.
