Laser sensor for driver assistance system for detecting surrounding of car, has transmission unit with laser diodes generating laser beams, where scanning of laser beams takes place in plane around angular distance

摘要

The sensor has a transmission unit and a receiving unit, where the transmission unit comprises a predetermined number of laser diodes (28) for generating appropriate laser beams. The laser beams are formed in a fan-shaped arrangement, where outer laser beams define a detection angle. The laser beams are arranged at a predetermined angular distance, where scanning of the laser beams takes place in a plane around the angular distance.
