定位技术在车辆防撞中的应用研究
Research on the Application of Positioning Technology in Vehicle Collision Avoidance

为减少因视线不佳导致的汽车碰撞事故，提出结合超声波和红外线进行测距，使车辆行驶时保证相互间的安全距离，该方案具有成本低廉、简单可靠的优点。进一步提出融合GPS和5G定位技术，使无线基站和低轨卫星互为补充，打造广域无缝覆盖的通信和定位网络。通过定位汇聚和分发过程，使参与交通的车辆能准确感知周边车辆的位置，从而达到防撞效果。这为汽车自动驾驶技术的推广扫清了安全障碍，使汽车朝电动化、网联化、智能化、共享化的方向加速发展。
In order to reduce vehicle collision accidents caused by poor vision, the combination of ultrasonic and infrared ray is proposed for distance measurement to ensure safe distance between vehicles when driving. This scheme has the advantages of low cost, simplicity and reliability. Furthermore, GPS and 5G positioning integration technology is proposed to build a wide-area seamless communication and positioning network with complement of wireless base stations and LEO satellites. Through the positioning convergence and distribution process, vehicles participating in traffic can accurately sense the position of surrounding vehicles, so as to achieving the anti-collision effect. This clears the safety barrier for the promotion of auto-driving technology, and accelerates the development of vehicles towards electrification, networking, intelligence and sharing.
