Review on the Research of Intelligent Vehicle Safety Driving Assistant Technology

The present research status,necessity and progress on safety driving assistant technology are discussed.The safety driving assistant technology includes lane departure warning,preceding vehicle detection and safe distance maintaining between vehicles,pedestrian detection,driver behavior monitoring,vehicle motion control and inter-vehicle communications.The advantages and disadvantages of different type of sensors and the problems that existed in the practical application are represented.The single sensor solution cannot meet the requirement of reliability and adaptability to different circumstance,so the laser and radar technology are combined to solve the blurred image problem,the infrared sensor is used to enhance the reliability of machine vision recognition.The future safety driving assistant technology should adopt multiple sensors fusion technology,associated with the characteristic that millimeter-wave radar and laser radar system are precise in depth measurement,to promote the application and improvement of the safety driving assistant system.
