Abstract
Radar and LiDAR sensors play important roles in autonomous vehicles and ADAS (advanced driving assistance systems) in automobiles, however, they can only detect objects in view (line-of-sight). For example, when three vehicles are driving on road in a same lane, and if the first vehicle suddenly brakes, the third vehicle cannot detect it by regular radar and/or LiDAR because the second vehicle in front blocks the view. This invention discloses system and method to enable radar and/or LiDAR to detect vehicles on road that are blocked in view by another vehicle by specially configured active beacon transmitters, and reduce risks of rear-end collisions.
