摘　　要：汽车的智能网联化带来了“软件定义汽车”的变革,使得嵌入式软件深度参与到汽车的定义、开发、验证、销售和服务等过程中。整车控制器,作为汽车的大脑,其软件的质量直接影响着整车的性能。当量产车的整车控制器软件出现故障或需要进行功能升级时,如果采用线下的方式处理,执行过程会非常繁琐复杂,并可能引起用户抱怨。为此,FOTA作为一种客户和汽车厂商双赢的远程升级技术已经逐渐被认可并走向普及的未来。The intelligent network of automobile has brought about the transformation of"software-defined vehicle",which makes embedded software deeply involved in the process of automobile definition,development,verification,sales and service.The software quality of the vehicle controller,as the brain of the vehicle,directly affects the performance of the vehicle.When the vehicle controller software of equivalent production vehicle fails or needs to be upgraded,the execution process will be very cumbersome and complex if it is handled offline,and may cause complaints from users.For this reason,FOTA,as a remote upgrade technology for both customers and automobile manufacturers,has been gradually recognized and will become popular in the future.
