| Abstract: | 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. |
