产品名称:C-WAVE系列V2X驾驶辅助系统

产品介绍:

    北京星云互联科技有限公司是依托清华大学技术团队和智能车路协同产业联盟的一家专注于新一代智能交通系统和智能车路协同技术的高科技企业。

C-WAVE系列V2X驾驶辅助系统是星云互联公司推出的具有完全自主知识产权的辅助驾驶综合解决方案,重点面向车辆安全和出行效率。自2015年底诞生以来,该系统目前已形成了成熟且完整的产品体系,并初步投入市场应用。

产品特点、优势和创新如下:

u  完全自主的软硬件整体方案

C-WAVE系列产品从硬件设计、生产,到应用软件的研发,均为公司团队自主完成。属于国内最早的完全自主知识产权的V2X软硬件整体解决方案之一。

u  创新性的多模式“中间层”平台

本产品率先提出和实现了支持底层多模式通信的V2X“中间层”平台,将上层V2X应用和底层通信技术相隔离。产品集成了5.8GHz的IEEE 802.11a短程无线通信,Wi-Fi通信,和2.5G/GPRS通信,同时支持外接国外DSRC/IEEE 802.11p通信技术、国内的LTE-V技术、EUHT高速宽带无线移动通信技术等。“中间层”平台,有效地对底层多模式通信进行了整合与管理,直接为上层应用提供便捷的软接口。

这项创新性的技术也正是解决了目前国内各种通信技术并存而导致上层应用难以实现的困境。

u  丰富的辅助驾驶应用

产品目前集成了如下V2X应用场景:1)车车碰撞预警(包括交叉路口碰撞、匝道口碰撞、追尾、一般侧碰等);2)行人、非机动车碰撞预警(借助于路侧的微波传感器);3)前车刹车提示;4)车辆盲区预警;5)信号灯实时状态提示;6)车速引导;7)交通标志标牌提示;8)交通事件通知(施工区、事故等);9)紧急车辆避让;10)危险车辆提示。

u  极其简洁高效的系统设计

整个系统由车载盒子(包括天线)、车载提示终端、路侧通信机三部分组成,结构简洁、高效。特别是车载盒子,在集成了计算、存储、定位模块,及多种通信模块情况下,将尺寸维持在150mm*130mm*40mm以下,功耗不超过4W,完全适合车辆的后装。

目前C-WAVE系列产品已在清华大学校园、国家智能网联汽车(上海)试点示范区、芜湖市中心城区、包头市石拐区等地投入使用。

 

ProductC-WAVE Serial V2X-based Driver Assistance System (C-DAS)

Introduction:

C-DAS is an integrated solution for Driver Assistance System (DAS) provided by Beijing Nebula Link Technology Co. Ltd. The system aims to enhance the safety and efficiency in vehicle driving via V2I communication. The whole project is supported by a technical group from Tsinghua University.

Although C-DAS is only half year old, its serial products have become mature enough to enter some advanced markets.

Advantages and innovations are as follows.

n  Completely independent intellectual solution of both hardware and software

Our company designed and developed all the hardware and software systems of C-DAS independently. C-DAS is one of the earliest V2X solutions with independent intellectual property rights in China.

n  An innovative mid-layer platform

C-DAS created a mid-layer platform of V2X that was able to support multiple communication technologies at physical layer. Such platform integrates different communication technologies as IEEE 802.11a, DSRC, LTE-V, EUHT, Wi-Fi, GPRS etc., and provides uniform API for upper-layer V2X applications. Therefore, this innovative platform solved the conflict between different communication technologies and the development of applications.

n  Rich V2X applications integrated

C-DAS has now integrated 10 kinds of applications as follows: 1) V2V Collision Warning (including collision at intersections and ramps, rear-end collision, side collision etc.); 2) V2P Collision Warning (with the help of road-side microwave detector); 3) Warning of Vehicle Brake Ahead; 4) Warning of Blind Region of Vehicle; 5) Real-time Traffic Light; 6) Speed Guidance; 7) Traffic Sign Warning; 8) Traffic Incident Warning (Such as road construction, traffic accident etc.); 9) Emergent Vehicle Yield; 10) Danger Warning.

n  Concise but very effective system design

The whole C-DAS system consists of only three parts: OBU Box, Display Terminal and RSU Communication Box. Particularly, even the OBU box is integrated multiple modules, its size is below 150mm*130mm*40mm and the power is below 4W. There will be no problem to equip the box in vehicle.

So far, C-DAS products have been used in Tsinghua campus, National Intelligent Connected Vehicle (Shanghai) Pilot Zone, Wuhu and Baotou.
