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

Abstract

An embodiment of the present invention provides a CANoe based ECU (Electronic Control Unit) software refresh method. The method comprises the following steps: in a refresh tool developed by using CANoe, selecting the type of an ECU that needs refreshing, and selecting a Flash drive BIN file, an application software BIN file and an application data BIN file; determining whether the type of the ECU that needs refreshing matches the application software BIN file or not; and if the two matches each other, uploading the Flash drive BIN file, the application software BIN file and the application data BIN file, and refreshing corresponding ECU software in the ECU. An embodiment of the present invention provides a CANoe based ECU software refresh apparatus. With implementation of the CANoe based ECU software method and apparatus provided by the embodiments of the present invention, refresh cost of the ECU software can be reduced, dependence on a provider can be reduced, and security is improved.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a CANoe-based ECU software refreshing method and device. Background technique [0002] With the development of automotive electronic technology, electronic controllers (Electronic Control Unit, ECU) are more and more 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 ...
