【摘要】 随着智能网联汽车以及软件定义汽车时代的来临，为实现功能迭代，加剧了车载控制器软件升级的频率，同时信息娱乐控制器提供的功能也越来越丰富，随之，软件升级包也越来越大，远程升级花费的时间也越来越长，且在升级时用户无法使用车辆，即在远程升级时存在用户等待升级时间长、汽车蓄电池电能消耗大、汽车亏电抛锚、续航里程减少等新挑战。为此，文章提出一种分布式远程升级的解决方案，经过台架和实车测试验证，基于车载控制器分布式远程升级可实现大文件的软件升级，从而缩短软件远程升级时间，同时减少汽车蓄电池电量消耗，有利于提高汽车蓄电池的寿命。更多还原

【Abstract】 With the advent of the era of intelligent connected vehicles and software-defined vehicles, in order to achieve function iteration, the frequency of vehicle controller software upgrade is intensified. At the same time, the functions provided by infotainment controllers are becoming more and more abundant, and the software upgrade package is getting larger and larger, and the remote upgrade takes longer and longer, and users cannot use the vehicle during the upgrade. That is, in the remote upgrade, there are new challenges such as long waiting time for the user to upgrade,large consumption of car battery power, car power failure, and reduced driving range. Therefore, this paper presents a distributed remote upgrade solution. Through bench and real vehicle tests, the distributed remote upgrade of vehicle controller realizes the software upgrade of large files, thereby shortening the software remote upgrade time, reducing the battery power consumption, and improving the battery life.更多还原
