本文提出一种基于地址选择的车载控制器程序执行策略，旨在解决车辆智能化背景下“控制器种类多、程序维护难”的问题。通过控制器开关量端口采集地址选择线接地状态，结合带电可擦可编程只读存储器（Electrically Erasable Programmable Read Only Memory，EEPROM）非易失性存储的预设标志位，实现单个程序在不同控制器中精准执行对应功能块。实际应用表明，该策略可将某车型车身控制相关维护程序数量从 3 套减至 1 套（减少约 67%），控制器硬件复用率提升至 100%，同时地址识别准确率达 100%（100 组工况测试无识别错误），显著降低程序维护难度与硬件成本。

This paper proposes a program execution strategy for vehicle-mounted controllers based on address selection, aiming to solve the problems of diverse controller types and difficult program maintenance amid vehicle intelligence. By collecting the grounding status of address selection lines through the controller's digital input ports and combining with the preset flags stored in EEPROM (non-volatile memory), a single program can accurately execute the corresponding function blocks in different controllers. Practical application results show that the proposed strategy reduces the number of body control maintenance programs for a specific vehicle model from 3 sets to 1 set (a 67% reduction), increases the controller reusability to 100%, and achieves 100% address recognition accuracy in 100 groups of tests without any error. The strategy effectively lowers program maintenance difficulty and hardware costs.
