摘要
结合国内外OEM厂商广泛采用的诊断协议UDS,对Can总线下的ECU在线重编程进行研究和设计,并对具体的软件实现进行阐述。本方案能防止ECU在线重编程过程中出现异常时,ECU被锁死;可自恢复,刷新功能永不丢失。
In this paper, the research and design for the ECU on board reprogramming are conducted according to diagnostic protocol UDS which is widely used by many major 0EMs in the world, and some software design details are discussed as well. It can avoid dead lock while some abnormal error occurs during ECU on board reprogramming. The ECU can perform recover）/itself and the refresh function never loses.
