注意: 这项技术允许在高速公路上变换车道， 且允许超车(整个车队变换车道 超过路上的其他慢速车) 作者 flymyfinger (飞我指) 看板 Gossiping 标题 [新闻] 雷射导引 时速110公里睡觉也能开车 时间 Tue Jun 23 00:14:41 2009 ─────────────────────────────────────── (图解) http://www.udn.com/2009/6/22/NEWS/WORLD/WOR4/4975503.shtml 瑞典富豪汽车开发出雷射导引科技，能够使汽车驾驶人完全不用操控车辆， 而在时速110公里的车队中用餐、阅读、工作、看电视及休息。 英国每日邮报21日报导， 富豪汽车开发中的这种科技能够以感应器及无线科技完全锁定车子， 一次最多可以引导10辆，可望2年内推出。 它使用的感应器能够引导每一辆车子紧紧跟随前面的车子， 雷射以每秒50次的频率计算车子相对於其他车辆的正确速度。 唯一的引导及煞车功能由前导车的职业驾驶人执行。 这种系统将使得交通主管当局与汽车驾驶人重新思考公路交通规则中的传统「煞车距离」 富豪汽车预期这种车队中的车子保持约仅0.9公尺的间距即可，仍可保持距离。 驾驶人必须注册并缴交约每2.6公里5元台币的费用，而且必须事先登记，俾在指定时间或 特定交流道加入车队的最後面，使导引系统得以将它们与前方车辆的操控及煞车模式维持 一致。 一旦驾驶人抵达事先指定的脱队位置，这种新科技将引导他们进入指定的交流道。如果配 备适当的科技，其他厂牌的汽车也能够加入这种车队。 富豪汽车与包括英国雷卡度科技公司在内的另外6家公司共同参与这项计画， (British technology firm Ricardo UK) 预定明年底在瑞典戈登堡郊区的富豪试验道路测试这种系统， 2011年推出原型系统，2018在欧洲各地推广。 富豪汽车表示，这种车队的经济效率比单独行进的汽车高20%到40%， 因为缩短车距可以大幅降低风阻。 =============== 看完外电文章，下一步当然是找英国每日邮报原文: http://www.dailymail.co.uk/sciencetech/article-1194481/ Lasers-guided-cars-allow-eat-sleep-wheel-travelling-70mph-convoys.html 缩: http://tinyurl.com/mu59yn 摘: Drivers would pay a subscription of around 10p for every 1.6miles travelled 我注意的是提升道路容量 (因为车距三英尺) 後面这段联合报没翻: Jonas Ekmark, a safety researcher at Volvo cars, said: ‘It would be the same as sitting on a bus or a train, with the big difference that when you come to your exit you take over and you go directly to your destination without having to switch vehicles. ‘The professional driver leading the convoy will be responsible for the safety of those behind him. But those joining the convoy will be taking only the same sort of risks that those jumping on a bus or tube are taking.’ Inventors have been investigating ‘car trains’ since the 1990s but previous projects have failed because they required dedicated roads to be built. A number of Volvo models already feature an automatic braking system capable of preventing low-speed rear-end collisions. (给现在销售中的车做广告) And a Volvo due to go on sale next year will include a pedestrian collision avoidance system that uses a camera, image recognition software and a radar. A short-range radio frequency has been reserved across Europe for the exchange of data between cars – making convoys possible. Tom Robinson, of Ricardo UK, said: ‘One of our goals is to use as many existing sensing systems and components as possible.’ === http://en.wikipedia.org/wiki/Car-trains --
