[国际新闻] 前后都装“眼” 无人驾驶汽车德国问世

你是否曾想像过,有一天驾车上班的路上,不必再全神贯注地手把方向盘、脚踩刹车,而是悠闲地看报纸、喝茶或聊天,因为有全自动无人驾驶汽车载着你在车海中灵活穿行。如今,德国一家公司应用先进科技把无人驾驶汽车变成了现实。 & `/ C' x0 |7 B$ |* {% L

  在无人驾驶技术研究方面位于世界前列的德国汉堡Ibeo公司研制的无人驾驶汽车,11日在英国伦敦科学博物馆与公众见面。这辆无人驾驶智能汽车经德国大众汽车公司生产的帕萨特2.0改装而成,外表看来与普通家庭汽车并无差别,但却可以在错综复杂的城市公路系统中无人驾驶。这归功于车内安装的无人驾驶设备,包括激光扫描仪、全球定位仪和智能计算机。

  德国Team Lux公司已将这种无人驾驶技术应用于家庭车型。“目前,无人驾驶汽车还不能合法上路,但它早晚能做到,”Team Lux公司工作人员弗尔克尔•威尔霍夫特说,“我们能将这种(无人驾驶)设备安装在家庭汽车上,这将使我们的社会更加安全。”
