7.￿Collision￿Warning
The￿camera-based￿collision￿warning￿is￿part￿of￿the￿Active￿Driving￿Assistant￿optional￿equipment
(OE 5AS)￿in￿the￿G12￿and￿is￿implemented￿using￿the￿KAFAS￿stereo￿camera.
The￿collision￿warning￿in￿the￿new￿BMW￿7￿Series￿contains￿the￿familiar￿"Collision￿warning￿with￿city
brake￿activation"￿and￿the￿"Pedestrian￿warning￿with￿city￿brake￿activation"￿functions.
In￿vehicles￿with￿the￿Active￿Cruise￿Control￿with￿Stop&Go￿function￿optional￿equipment￿(OE ZN7),
the￿cruise￿control￿radar￿sensor￿is￿also￿used￿to￿control￿the￿collision￿warning.
Vehicles￿with￿the￿Active￿Driving￿Assistant￿Plus￿optional￿equipment￿(OE 5AT)￿have￿the￿Active￿Cruise
Control￿with￿Stop&Go￿function￿optional￿equipment￿(OE ZN7)￿integrated￿as￿standard.
If￿the￿vehicle￿is￿not￿equipped￿with￿the￿Active￿Driving￿Assistant￿(OE 5AS)￿or￿Active￿Driving￿Assistant
Plus￿(OE 5AT)￿optional￿equipment,￿but￿does￿have￿the￿Active￿Cruise￿Control￿with￿Stop&Go￿function
optional￿equipment￿(OE ZN7),￿the￿customer￿also￿receives￿a￿collision￿warning.￿However,￿in￿this￿case
the￿pedestrian￿warning￿is￿not￿included.
The￿system￿warns￿the￿driver￿in￿situations￿where￿a￿collision￿is￿imminent.￿The￿early￿warning,￿a￿visual
signal,￿is￿issued￿first￿to￿draw￿the￿driver's￿attention￿to￿the￿situation.￿If￿the￿situation￿becomes￿more
critical,￿an￿acute￿early￿warning￿in￿the￿form￿of￿a￿visual￿and￿acoustic￿signal￿is￿issued.￿The￿nature￿of￿the
warning￿is￿such￿that￿the￿driver￿can￿still￿prevent￿a￿collision￿providing￿he￿acts￿quickly.
7.1.￿Functional￿principle
The￿KAFAS￿stereo￿camera￿captures￿the￿scene￿in￿front￿of￿the￿vehicle￿and￿detects￿entire￿rear￿views
of￿moving￿and￿stationary￿vehicles￿in￿the￿field￿of￿view￿using￿image￿processing.
In￿vehicles￿with￿the￿Active￿Cruise￿Control￿with￿Stop&Go￿function￿optional￿equipment￿(OE ZN7),￿in
addition￿to￿the￿KAFAS￿stereo￿camera￿image￿data,￿information￿from￿the￿radar￿sensor￿is￿also￿evaluated.
