Abstract:With the rapid development of intelligent connected vehicles, cars are no longer a simple tool for transportation, but an ecological subject full of personality, experience and scenes. Many colorful new functions have been introduced into cars. With the increase of a large number of functions, there are more and more electronic devices of intelligent networked vehicles, and the network architecture becomes very complex. The traditional CAN network CAN no longer meet the needs of the rapid development of intelligent networked vehicles. To this end, the paper puts forward a network architecture, which has the powerful computation ability and expanding ability and advantages of the openness, and can flexibly interact with external devices, transmit data quickly, upgrade OTA software, and fully make up for the deficiency of the traditional CAN network, so as to meet the needs of the development of the intelligent made cars.
Key words:car, ring ethernet, architecture, application

隨着智能网联汽车科技的不断进步,我们经常可以看到与汽车相关的如下的场景:1)汽车被摆放在展厅上,车灯呈现个性化地闪灭;2)汽车与机器人在舞台上共舞,十分具有科技感;3)一些改装车的的转向灯改装成跑马灯的形式,显得更加美观。在很多场景中,汽车已经不只是一个简单的代步工具,而更是身份的象征,是用于炫耀、展示的艺术载体。
为了满足以上丰富多彩的场景需求,汽车需要与更多的外部设备互联,汽车的设计理念因此也需要从传统的单单关注性能提升转型为更多的功能拓展和跨界融合。新型的智能网联汽车需要具备更为强大的计算存储和通信能力,给外部预留足够的硬件接口,软件也需要满足可移植、可迭代、可拓展的技术特征,整个系统做到完全开放。……
