智能车辆安全辅助驾驶技术研究近况

论述了安全辅助驾驶技术的研究现状、研究的必要性以及研究进展。安全辅助驾驶技术包括车道偏离预警与保持、前方车辆探测及安全车距保持、行人检测、驾驶员行为监测、车辆运动控制与通讯等。分析了各种传感器的优缺点及其在实际应用过程中存在的问题,基于单一传感器不能很好地解决安全辅助驾驶技术可靠性和环境适应能力的要求,应结合激光雷达技术解决图像模糊问题,利用红外传感器增强机器视觉识别的可靠性,未来的安全辅助驾驶技术应该采取多种传感器融合的技术,结合毫米波雷达和激光雷达系统具有深度测量精确的特点,将极大的推动汽车安全辅助驾驶系统的应用和推广。

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.
