Embodiment Construction

[0043] In this patent, the refresh device communicates with the refreshed node about the upgrade time, so as to avoid the inability to communicate and respond during the ECU upgrade process, causing the refresh device to mistakenly believe that the ECU upgrade has failed. The specific implementation will be further described below in conjunction with the accompanying drawings and examples.

[0044] Such as figure 1 As shown, the embodiment of the present invention provides an adaptive electronic control unit software upgrade method. Before upgrading according to the method, the refresh device and the refreshed node will interact to read the version, enter the extended mode, Disable DTCs and communication controls, etc.

[0045] In this embodiment, a software upgrade time command interaction will be performed between the refresh device and the refreshed node, the refresh device will request to send the software upgrade time to the refreshed node, and the refreshed node will rep...

Abstract

The invention provides a self-adaptive electronic control unit software upgrading method and system and an automobile. The method comprises the steps that refreshing equipment sends a request instruction of software upgrading time to a refreshed node, and the refreshed node replies the required software upgrading time to the refreshing equipment; the refreshing equipment configures software upgrading waiting time according to the software upgrading time required by the refreshed node, and the software upgrading waiting time is greater than or equal to the software upgrading time; the refreshing equipment transmits a software upgrade package to the refreshed node; and after the transmission of the software upgrading package is completed, the refreshing equipment waits according to the software upgrading waiting time, so that the refreshed node completes software upgrading. The problem that the refreshing equipment mistakenly considers that the upgrading fails due to the fact that communication response cannot be performed in the ECU upgrading process of the refreshed node is solved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an adaptive electronic control unit software upgrading method, system and automobile. Background technique [0002] Since the current Electronic Control Unit (Electronic Control Unit, ECU) gradually begins to use the System of Chip (SOC) and various operating systems, it cannot match the traditional software upgrade process, and the ECU will upgrade the software. During the upgrade, it takes several minutes or even ten minutes for the self-update process. During this process, the ECU cannot communicate and respond, which will cause the refresh device to think that the upgrade has failed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an adaptive electronic control unit software upgrade method, system and automobile, which are used to solve the problem that the refreshed node cannot respond to communication during...
