Embodiment Construction

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0043] The applicant found that the existing upgrading scheme for upgrading the ECU has at least the following defects:

[0044] 1) The OEM needs to discuss the upgrade process plan with TBOX suppliers and ECU suppliers, and then needs to request the upgrade plan of the ECU to be upgraded according to the discussed upgrade plan, so that the ECU can complete the adaptation of the discussed upgrade plan, which greatly Increased development time and development complexity, high manpowe...

Abstract

The invention discloses an upgrading method and device for dynamically adjusting a flashing process. According to the method and device, different upgrading flashing processes corresponding to a plurality of different components (such as a whole vehicle ECU) are integrated in advance to obtain a universal upgrading flashing process which covers the different upgrading flashing processes of the different components and does not have repeated steps; on the basis, for the target component to be upgraded, the universal upgrading and flashing process and the specific upgrading configuration information of the target component are carried in the upgrading package, so that the universal upgrading and flashing process can be configured based on the specific upgrading configuration information of the target component; and obtaining a target upgrading and flashing process adaptive to the target component and finishing upgrading. Therefore, for different parts, such as the whole vehicle ECU, the ECU development complexity is reduced, and the whole vehicle ECU development period is shortened within a certain range; in addition, the whole upgrading scheme is more flexible and has a better platform effect.

Description

technical field [0001] The present application relates to the field of component software upgrades, and in particular to an upgrade method and device for dynamically adjusting the flashing process. Background technique [0002] In today's automotive field, the software of electronic control unit (ECU, Electronic Control Unit) is changing with each passing day. It is often required to upgrade the software of ECU (such as ECU after loading) to meet the requirements of ECU. normal work requirements. [0003] Wherein, the component performing the upgrade is usually a TBOX (a type of ECU), and the TBOX is responsible for flashing the upgrade data to the ECU to be upgraded to complete the upgrade of the ECU to be upgraded. At present, regarding the data flashing scheme of using TBOX to upgrade ECUs, TBOX suppliers, OEMs, and ECU suppliers generally discuss the corresponding fixed upgrade flashing process for each ECU to be upgraded, and the OEMs flash according to the matching fi...
