Example Embodiment

[0036] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] Such as figure 1 What is shown is an embodiment of a method for remote after-sales online refreshing of an ECU according to an embodiment of the present invention, and the method specifically includes:

[0038] Step S101: The diagnostic device requests verification from the remote server, and after the verification is passed, it sends a query request to the server to obtain the corresponding vehicle configuration information, and the corresponding multiple refresh ECU part numbers and the software corresponding to each refresh ECU version number;

[0039] The specific process is that the diagnostic device sends an application code to the remote server for verification, and after receiving the authorization code fed back by the server, the verification is determ...

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...
