OTA实现方案及汽车端设计分析

OTA Implementation Plan and the Vehicle Design Analysis

智能网联汽车时代,软件已逐步成为汽车的核心竞争力。汽车OTA能够实现汽车软件的远程升级,可以提升用户体验,降低车厂由于软件缺陷带来的召回成本,已成为智能网联汽车的关键技术。汽车内控制器数目、种类繁多,软硬件差异较大,因此汽车OTA技术对汽车设计将带来一定的挑战。文章介绍汽车OTA系统的组成,OTA管理平台的结构和功能,重点分析OTA技术对汽车端的要求和汽车端的实施方案。

In the era of intelligent connected vehicle(ICV), software has gradually become the main competitiveness of the vehicle. OTA can realize the remote upgrade of vehicle software, improve the user experience and reduce the recall cost due to software defects, which has become the key technology of ICV. There are many kinds of controllers in the vehicle, and the difference between software and hardware is large. So the vehicle OTA technology will bring some challenges to the vehicle design. This paper introduces the composition of vehicle OTA system, the structure and function of OTA management platform, and analyzes the requirements and implementation plan of OTA technology for the vehicle.
