Blind spot (vehicle)#Blind Spot Information System

The lane change assistant (or Blind Spot Assist ) is a driver assistance system to warn the driver of impending collisions when changing lanes.

Operation

The detection of approaching vehicles in the adjacent lane by means of radar sensors (24 GHz or 77 GHz), cameras or laser scanners. Alerts to the driver done in different ways, depending on whether the direction indicator ( " flasher " ) has been pressed or not.

In the event that no turn signal is actuated, at best, a visual warning will be issued. If the turn signal active, however, a higher alert level is activated when the warning is insistent, usually visually by rapidly flashing lights, mostly in the field of mirrors, acoustic means of warning sounds or haptic vibration of the steering wheel, the driver's seat or the turn signal lever.
