The invention discloses a semi-trailer blind area track early warning method and device for an external environment, and relates to the technical field of vehicle driving safety, the semi-trailer blind area track early warning device is provided with four inner wheel difference coverage area mapping point positions of the left side of a tractor body, the left side of a semi-trailer body, the right side of the tractor body and the right side of the semi-trailer body, and each point position is provided with a front straight laser lamp and a rear straight laser lamp. The formed early warning device can greatly increase the turning early warning area, early warning is carried out on the path which is not passed by the semitrailer when the semitrailer turns, the response time of pedestrians or non-motor vehicles is prolonged, and potential safety hazards are greatly reduced. The early warning area of the device is based on real-time calculation of the turning inner wheel difference, and the early warning area is dynamically adjusted along with the vehicle driving state and is more accurate.

    本发明公开了一种针对外部环境的半挂车盲区轨迹预警方法及装置,涉及车辆行驶安全技术领域,其具有牵引车体左侧、半挂车体左侧、牵引车体右侧和半挂车体右侧四个内轮差覆盖区域映射点位,每个点位具有前后两个一字激光灯,所形成的预警装置可大幅增加转弯预警面积,并对半挂车转弯时未经过路径进行提前预警,增加了行人或非机动车辆的反应时间,极大减少了安全隐患;装置预警区域基于对转弯内轮差的实时计算,预警区域随车辆行驶状态动态调节,更加准确。
