Vspy-based ECU software refreshing method and Vspy-based software refreshing device

Abstract

An embodiment of the invention provides a Vspy-based ECU software refreshing method which comprises the steps of selecting the type of the ECU software to be refreshed in a refreshing tool which is developed based on Vspy; according to the selected type of the ECU software to be refreshed, reading the storage address of a refreshing file which corresponds with the type of the ECU software; in the storage address, reading a safe algorithm file which corresponds with the type of the ECU software, a Flash driving file and a refreshing file to be uploaded; uploading the refreshing file to the ECU of a passenger vehicle, and refreshing the corresponding ECU software in the ECU. The embodiment of the invention correspondingly provides a Vspy-based software refreshing device. The Vspy-based ECU software refreshing method and the Vspy-based software refreshing device have advantages of reducing refreshing cost of the ECU software, increasing refreshing speed, improving refreshing success rate, reducing dependence on a provider and improving confidentiality.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a Vspy-based ECU software refreshing method and device. Background technique [0002] With the development of automotive electronic technology, electronic controllers (Electronic Control Unit, ECU) are increasingly used in modern automotive technology. During the development of electronic controller software and during the use of automotive products, due to the upgrade of control software, software developers and automotive OEMs need to refresh the controller software. The controller software is generally stored in the flash area of ​​the chip that can be repeatedly electrically erased. Using the existing software refresh method, the staff needs to open the controller and use the BDM (background debug module) port to perform Flash programming. The actual operation is very inconvenient . [0003] In the prior art, there is another refreshing method, which is to us...

Problems solved by technology

Moreover, engineers cannot independently adjust the refresh code according to their own needs, and once the software refresh specification is changed, they need to change the source code through Vector and pay Vector a certain development fee, which increases the development cost of the entire vehicle; The requirement is notified to Vector, so at the same time, the confidentiality of the software update specification of the automobile OEM is reduced

Moreover, in the existing refresh method, it is necessary to operate and fill in multiple parameters before the refresh starts, and the operator needs to select multiple files. There are many operations, and it is difficult to avoid parameter filling errors or The loaded file does not match the required file, etc. If this happens, it will affect the production cycle, and even cause unnecessary waste or serious consequences when the wrong software is installed.
