无人驾驶汽车编队雾天主动拯救系统

Active Rescue System of Unmanned Vehicle Platoon in Fog Weather

为减少雾天公路上由于有人驾驶汽车车速过高引发的交通事故,为无人驾驶汽车编队设计了一种主动拯救系统。当系统检测到编队附近有人驾驶汽车车速过高且前方有障碍物时,它能控制编队通过变道和队形变换形成编队屏障,迫使有人驾驶汽车在碰撞前降低车速而避免碰撞事故。为验证所提出的主动拯救系统的有效性,设计了两组仿真进行了对比。仿真结果表明,所设计的系统能有效降低有人驾驶车辆在雾天的碰撞事故。

For reducing the traffic accidents caused by the overspeed of manned vehicles on road in fog weather, an active rescue system is designed for unmanned vehicle platoon. When the system detects the overspeed of an manned vehicle with obstacles in front of it, the platoon can controlled to form a barrier by lane-change and changing formation to force the manned vehicle to reduce speed before collision and avoid accident. To verify the effectiveness of the proposed active rescue system, two simulations are conducted for comparison. The results of simulation show that the proposed system can effectively reduce the collision accidents of manned vehicles in fog weather.
