摘　　要：采用分层和模块化思想设计出一种基于ASAP标准的标定诊断系统。在上位机利用软件看门狗技术,解决了标定工具与发动机电控单元之间的故障快速定位问题。故障时上位机自动保存标定数据,故障修复后自动下发该标定数据,进而防止标定数据丢失,避免重复性的标定工作。并能读取国外标定系统的数据库文件,其可靠性和通用性进一步增强。A calibration and diagnosis system based on ASAP standards was designed using layer and modularization idea. the malfunction between host computer and ECU was positioned quickly through the software watchdog technology in the host computer, and the calibrated datas were autosaved into the Caliration tool. After the malfunction was repaired ,these datas were sent to the RAM of ECU. So this can avoid the datas＇losing and the calibration＇s repetition. Also it can read foreign calibration software＇s description file.it＇s reliability and universality was strengthened.
