Embodiment Construction

[0043] In this patent, the specific implementation is further described below with reference to the accompanying drawings and examples.

[0044] like figure 1 As shown, an embodiment of the present invention provides an OTA-based multi-ECU upgrade method, and the method includes:

[0045] Step S11, the target vehicle acquires an upgrade task, the upgrade task includes the identifiers of multiple target ECU controllers corresponding to the identifier of the target vehicle, the link address of the upgrade software package corresponding to the identifier of each target ECU controller, and The upgrade sequence is determined by the dependencies between the upgrade software packages.

[0046]In this embodiment, the target ECU controllers to be upgraded are ECUA, ECUB, and ECUC respectively, and the dependencies of the upgraded software packages are ECU C version 3->ECU B version 2->ECU A version 1, that is, ECU A version 1 depends on ECU B version 2, ECU B version 2 depends on ECU...

Abstract

The present invention provides an OTA-based multi-ECU upgrade method. The method includes acquiring an upgrade task for a target vehicle, and the upgrade task includes identifiers of multiple target ECU controllers corresponding to identifiers of the target vehicle, and identifiers of each target vehicle. The link address of the upgrade software package corresponding to the identifier of the ECU controller and the upgrade sequence determined by the dependencies between the upgrade software packages; the target vehicle is based on the upgrade software corresponding to the identifier of each target ECU controller. The link address of the package is obtained, and the upgrade software package corresponding to the identifier of each target controller is respectively obtained; the target vehicle sequentially upgrades each target ECU controller according to the upgrade sequence. The invention solves the problems of cumbersome update task release time, long update time and low update efficiency when multiple ECU controllers of existing vehicles are updated.

Description

technical field [0001] The invention relates to the technical field of car networking, in particular to an OTA-based multi-ECU upgrade method. Background technique [0002] With the development of automotive intelligent networking, the automotive networking is playing an increasingly important role, and automotive ECU controllers such as IVI (In-Vehicle Infotainment ， In-vehicle infotainment system), TBOX, ADAS (Advanced Driving Assistance System) and new energy ECU (Electronic Control Unit, electronic control unit) controllers compared with traditional vehicles, software update iterations are more and more, to provide users with Better user experience. OTA (Over the air, remote download) provides an online upgrade method. Just like the mobile phone system upgrade, you can click the upgrade on the interface to complete the vehicle system upgrade, which is more efficient, convenient and cost-saving than the traditional offline 4S store after-sales upgrade software. and bett...
