Blind Spot Intervention

ＢＳＩ (Blind Spot Intervention)
1) BSI issues an audible and visible warning upon activation of turn signal when a vehicle
is in the blind spot.
2) When the vehicle approaches the adjacent lane, BSI issues an audible and visible
warning and in addition, helps the driver to maneuver the vehicle back into the original
driving lane by generating a yaw moment.
BSI helps the driver when changing lanes by providing information and assistance to help avoid a vehicle in the blind spot.
