基于车载以太网的环视系统设计

Surround View System Design Based on the Ethernet of the Vehicle

摘要: 社会的进步是需要第一个吃螃蟹的，本环视系统是国内首个使用车载以太网传输视频的系统，在设计以及量产的过程中遇到的各种问题是一种宝贵的财富，给广大车企未来的变更带来了经验和方向。本产品设计之初考虑到的升级功能，通过控制器对环视摄像头的升级能力，通过CAN FD总线以及ORU功能对环视控制器的升级设计给产品的更新带来了无限可能。本产品可以实现简化车载网络架构，消减线缆成本，在传统以太网成熟技术的背景下降低开发风险，随着后续感知器件的增加，实现传感器功能融合。

Abstract: The progress of society needs to be the first to eat crabs. This surround view system is the first system to use vehicle Ethernet to transmit video in China. Various problems encountered in the process of design and mass production are a kind of valuable wealth, which brings experience and direction to the future changes of the majority of automobile enterprises. At the beginning of the design of this product, the upgrade function is considered. Through the upgrade ability of the controller to the surround view camera, and through the upgrade design of the CAN FD bus and ORU function to the look around controller, it brings infinite possibility to the update of the product. This product can simplify the vehicle network architecture, reduce the cable cost, reduce the development risk under the background of traditional Ethernet mature technology, and achieve sensor fusion with the increase of subsequent sensing devices.
