一、C-V2X是什么
C-V2X,以蜂窝技术为基础的车联网,包含车对车(V2V)、车对行人(V2P)、车对基础设施(V2I)、基于网络的通信模式(V2N),能够让车辆、信号灯、交通标识、骑行者和行人的通讯设备实现互联。使车主准确及时获取前方道路信息状况,提升车辆在视线盲区的感知力,从而降低碰撞风险和改善道路拥堵。上面这段话或许还不能让你明白它到底是个啥,抛开繁琐,我们直接看它能干什么,你就豁然开朗了。
二、C-V2X能做什么
1.转向意图识别
通过与交管部门和基础设施供应商的紧密配合,福特SYNC+车机屏幕会实时接收当前路段的信号灯、限速标识等信息,显示前方路口信号灯的剩余时间,方便车主做好通行判断。
2.绿波车速引导
屏幕左侧的绿色横条就是绿波车速引导标识,根据前方路口的红灯剩余时间,可通过语音提醒驾驶者在条件允许的情况下按照推荐速度区间行驶即可直接通过路口,减少等待红灯时间,既节省油耗又提升整体交通效率。这确实是个非常实用的功能,但如果后方车辆不具备此系统,也很可能会误会我方车辆的意图。
3.闯红灯预警
可以使车辆实时接收前方信号灯的状态和剩余时间,结合自身车速、位置等信息做出判断,通过屏幕演示和语音更准确地推送预警信息,避免闯红灯风险。
4.行人碰撞预警
除了交通信号灯实时联网,空中的摄像头亦如此。可以将行驶路线中存在的行人提前告知,让驾驶者做出提前判断,减少碰撞发生的可能。
5.紧急刹车预警、侧向来车预警
当行驶路径上前方有车辆进行紧急制动,或驾驶者视野盲区外有车辆时,都会进行预警提醒。看到这,是不是觉得这些功能没什么?我们现在的车也有啊!有什么区别吗?当然有,而且很大!
三、和传统主动安全设备的区别
传统的汽车主动安全设备都是车辆自身的硬件感知,需要雷达、摄像头的配合来完成监测。而C-V2X则是完全依靠网络将信息告知驾驶者,车辆无需安装任何探测类设备,依靠车联网系统提醒驾驶者,将车辆自身变成一台无线传感器,记录自身的车辆状态、速度、行驶方向等信息,让每一台车都成为交通环境的一份子,具有更高的可预测性和准确性,监测和提醒范围要远远大于传统的汽车主动安全设备,是其有益的补充。提升盲区感知、避免碰撞风险、减少交通拥堵是它最显著的三个作用。如此带来的好处就是,福特把C-V2X与其车载系统SYNC+深度集成,将于2020年上半年通过OTA推送给试用车主。驾驶搭载 SYNC+系统的福特车型在江苏无锡特定公开道路上率先体验这种便利和高效的出行方式。
四、何时量产
自2017年以来,福特汽车在中国加速测试和评估C-V2X的性能表现,并最终将该技术得以在车辆上应用。今年七月,福特开始在无锡公开道路测试和验证V2I预商用功能的可靠性,截止目前,测试车辆在无锡已累计进行了超过2000小时的密集道路实测。福特中国将于2021年量产配备C-V2X技术的车型,比福特美国本土还要提前一年。随着5G技术的普及,C-V2X的即时性和可靠性将大大提升。通过与车辆的雷达和摄像头传感器配合工作,C-V2X将成为实现完全自动驾驶的重要辅助。目前,福特多款新车型上搭载的Co-Pilot360TM智行驾驶辅助系统已具备SAE L2级自动驾驶功能。这是一项我非常期待的技术,它不依靠传统硬件,却又为主动安全系统提供了巨大的辅助和补充,即使车辆自身没有盲区监测、行人识别、碰撞预警等功能,但有了C-V2X,我们依然可以把车开的很从容。 记得点“在看”哦!
