综述:东京车展展望车联网时代

新华社东京10月30日电  综述:东京车展展望车联网时代

新华社记者 钱铮

正在举行的第45届东京车展上,促进车辆之间、车辆和基础设施之间互联互通的车联网技术成为一大亮点,它不仅能提高道路交通安全、提升舒适度等驾驶体验,还派生出一些有趣、实用的功能。

丰田公司首次展出了皇冠概念车。这款定于2018年夏季上市的车型装有专用车载通信设备,用于收集车辆信息并传至数据中心,以便给车辆提供多种服务。

丰田展区解说员告诉记者,根据车辆传来的行驶状况等数据,数据中心可以分析出哪些区域拥堵,并把结果反馈给车辆导航。车辆如发生事故,系统能自动向中心紧急呼救,并传送车辆位置等信息,使中心能迅速掌握车辆在何处发生何种事故,并请求消防和警察救援。

再比如,车辆发生故障时,车载仪表盘会亮起报警红灯。多数人可能无法根据报警灯找到故障发生部位,这时可以求助数据中心,后者通过大数据分析判断车辆状况,并给驾驶员语音提示:“没大问题,可以坚持跑一段,到4S店去修理”,或者“出现这类警示,还是不要继续行驶了”等。

在展会特设的“东京连接实验室2017”主题展区,丰田的智能交通系统向公众展示了如何通过车辆之间以及车辆和道路、交通信号灯等基础设施之间的互联,提高驾驶安全性和道路通行率。比如,日本车辆靠左行驶,车辆在十字路口等待右转时,如果驾驶员视线被对面等待右转的大车挡住、看不到对面直行过来的车辆和行人,就容易发生危险。而安装在交通信号灯上的传感器可以捕捉这些车辆和行人,给驾驶员发送警示,还可以让驾驶员预知信号灯多久变灯、紧急车辆从哪个方向驶来以及和本车之间的距离等。

三菱汽车公司致力研发的车联网技术侧重汽车和家电的互联,以获得更舒适、便捷的驾车体验。据三菱汽车工作人员介绍,他们与亚马逊公司合作,将三菱汽车接入了亚马逊的Alexa智能语音服务平台。依靠这一基于云技术的平台,只要向专用终端亚马逊智能音箱Echo发出指令,就能实现远程控制车辆。比如,外出前让车辆提前打开空调;回家进屋后想起车门没锁,一句话就能锁上。

汽车共享业务近年来在日本迅速发展,但是要到约定地点取钥匙和还钥匙比较麻烦,所以个人间汽车共享多采用将闲置汽车交给租车公司打理的方式。为了简化汽车共享的流程,丰田展出了两个基于车联网的有趣应用——智能汽车共享和后备箱快递暂存。租车人可以在专用的汽车共享应用程序上预约车辆,当在约定时间来到汽车停放地点时,手机就能收到车主发来的电子钥匙,将手机靠近车辆就能开锁。

如果车主将电子钥匙设定为只能打开汽车后备箱模式,就能使停在家门口汽车的后备箱“秒变”快递存储柜。收到快递员的信息后,车主可以把后备箱的电子钥匙发送到快递员的手机,这样既能确保物品不丢失,又能节省快递员再次上门配送的时间,还不用专门开辟地方建存储柜,可谓一举多得。

东京车展始于1954年,前20届每年举办一次,之后改成每两年一届。它与巴黎车展、法兰克福车展、日内瓦车展和北美车展并称为世界五大车展,是日系汽车企业乃至整个汽车行业未来发展的风向标。

本次展会于27日正式开幕,28日至11月5日面向公众开放。
