Remote after-service on-line ECU refresh method and diagnosis apparatus

Abstract

The invention provides a remote after-service on-line ECU refresh method, which comprises the following steps: a diagnosis apparatus requests verify to a remote server; after verification succeeded, the diagnosis apparatus sends query request to the server to obtain the corresponding vehicle configuration information and the corresponding multiple ECU refresh part numbers and the corresponding software version numbers. Then the diagnosis apparatus reads the local ECU part number and determines the ECU refresh part number matched with the local ECU part number and the corresponding software version number; downloads the corresponding refresh configuration file and the refresh software from the server; imports the refresh configuration file and the refresh software; update the local configuration file and the refresh software automatically; and when the ECU part number in the configuration file after update and the ECU part number in the refresh software match with the local ECU part number, the local ECU software is refreshed by the updated refresh software. According to the embodiment of the invention, both the security of the refresh file can be guaranteed, and the manpower cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method and diagnostic equipment for remote after-sales online refreshing of an ECU. Background technique [0002] With the development of automotive electronics technology, the degree of automotive electronics is getting higher and higher, so that various software is being applied to cars more and more, not only in the entertainment system of the car, but also in some basic driving In terms of functions, such as steering, braking and acceleration, and even more advanced driving functions, such as adaptive cruise control and automatic parking. In fact, through the application of the above software, although it is easy to diagnose and solve problems in the car, it may also cause driving hazards due to bugs in the software itself. Therefore, software bugs require OEMs or parts suppliers to pass software Refresh to resolve. [0003] Software refresh is mainly to erase and pro...

AI Technical Summary

Problems solved by technology

At present, due to the security of the refresh file, the main engine factory usually does not issue the refresh file to the maintenance personnel of the component supplier in order to avoid the leakage of the refresh file. Therefore, the refresh and upgrade of the ECU often requires the engineers of the main engine factory to go to the site Brush writing, which greatly increases the labor cost
