1 System Description

Advanced driver assistance systems (ADAS) in a vehicle provide quality-of-life and safety benefits in addition to making the relatively mundane act of driving safe and less difficult. A key safety feature is BSD, which observes the area in the rear corners of the car and alerts the driver of vehicles approaching from behind in an adjacent lane. This feature increases safety by detecting obstacles that cannot be seen by the driver in the side-view mirrors and preventing collisions when changing lanes. BSD is implemented using a variety of sensors to detect obstacles in the environment and track positions and velocities over time.
