Problems solved by technology

[0003] At present, the MP5 and Tbox of most car manufacturers have the OTA upgrade function, but the CAN controller cannot be upgraded through OTA.
In addition, the OTA technology of MP5, tbox and other controllers is often mastered by the component suppliers themselves. The server is deployed at the supplier, and the OEM cannot directly manage it. It cannot effectively manage the life cycle of each controller of the vehicle, and there will be differences Components are upgraded at the same time, causing vehicle use conflicts

Abstract

The invention relates to an OTA upgrade system for a complete vehicle electronic control unit. Its server adaptation management module realizes the communication adaptation between the OTA server and the manufacturing system server; Update and revocation; the vehicle and equipment management module is used to generate the OTA upgrade target screening database; the upgrade package management module obtains the OTA upgrade program; the upgrade activity management module is used to determine the upgrade target vehicle through the OTA upgrade target screening database, and determine the OTA according to the upgrade target vehicle The OTA upgrade package in the upgrade program, and then add a security certificate to the OTA upgrade package, and upload the OTA upgrade package to the cloud; the upgrade agent module performs OTA upgrade according to the OTA upgrade package. The invention can realize the remote upgrade of the software of the electric control unit of the whole vehicle.

Description

technical field [0001] The invention relates to the technical field of automobile electronic control, in particular to an OTA upgrade system and method for an electronic control unit of a complete vehicle. Background technique [0002] The communication and interaction between smart devices and smart cars, the integration of multiple data sources in the Internet of Vehicles and version updates have become problems that car manufacturers and related standards departments need to solve. It is very important to consider how to update the software of the electronic controller using advanced over-the-air update technology (OTA, Over-The-Air) throughout the vehicle life cycle. [0003] At present, the MP5 and Tbox of most car manufacturers have the OTA upgrade function, but the CAN controller cannot be upgraded through OTA. In addition, the OTA technology of MP5, tbox and other controllers is often mastered by the component suppliers themselves. The server is deployed at the supp...
