2.￿Control￿Units
Both￿control￿units￿for￿blind￿spot￿detection￿SWW￿(primary)￿and￿SWW2￿(secondary)￿are￿shown￿in￿the
picture.￿The￿SWW￿(primary)￿control￿unit￿is￿located￿on￿the￿right.￿The￿control￿unit￿SWW2￿(secondary)
is￿on￿the￿left.
The￿control￿unit￿for￿blind￿spot￿detection￿SWW￿is￿required￿for￿the￿following￿optional￿equipment:

Active￿Sound￿Design￿ASD
The￿control￿unit￿for￿Active￿Sound￿Design￿generates￿the￿engine￿sound￿for￿the￿vehicle￿interior.￿The
engine￿sound￿is￿calculated￿according￿to￿the￿programmed￿sound￿specification￿and￿various￿parameters
such￿as￿the￿accelerator￿pedal￿angle￿(driver's￿desired￿load),￿engine￿speed￿and￿torque.￿It￿is￿then￿output
via￿the￿vehicle's￿own￿audio￿system￿in￿the￿passenger￿compartment.
