摘　　要：随着整车控制器功能更新的日趋频繁及控制器Bug修复需要,控制器软件刷写日趋频繁。为了验证数据在传输过程中的完整性,需要对其进行校验。校验值及校验算法集成和控制方式不同,目前较为普遍的做法主要有3种。本文将对其进行详细分析。With the increasing frequency of vehicle controller function updates and the need to repair controller bugs,controller software refreshing becomes more frequent.In order to verify the integrity of the data during transmission,it needs to be verified.The check value and check algorithm integration and control methods are different,and there are mainly three common practices at present.This article will analyze it in detail.
