Problems solved by technology

[0003] Since the development of the upgrade function of the vehicle ECU can only be carried out after the design and development of the whole vehicle is completed, that is, the development of the ECU upgrade function can only be carried out on the vehicle end after the completion of the development of the vehicle end, which will undoubtedly prolong the time to market of the vehicle and weaken the market for the product Competitiveness
At the same time, the vehicle manufacturers have a rich product line of models, many models with ECU configuration schemes, and vehicle updates and iterations are fast. The traditional ECU upgrade method needs to be constantly modified and added at the vehicle end to meet the ECU upgrade requirements of the OEM.

Embodiment Construction

[0047] A method for upgrading a vehicle ECU through a script, including the steps of a cloud platform and a remote controller at a vehicle end.

[0048] Such as image 3 As shown, the cloud platform 110 is used for users to edit the upgrade package online, store the upgrade package through the database, allow the user to retrieve the upgrade package from the database, and create cloud upgrade tasks according to the upgrade package selected by the user.

[0049] The cloud platform 110 provides a visual upgrade package editing interface, and the upgrade package editing interface generates an upgrade package according to the flashing file of the upgraded ECU, the security authentication algorithm library, the data verification library, the upgrade script and the upgrade strategy submitted by the user.

[0050] The cloud platform 110 provides a visual and interactive script editing interface, and the editing interface encapsulates script commands into command tags and parameter se...

Abstract

The invention discloses a method for upgrading a vehicle ECU through a script. The method comprises a vehicle-end remote controller step, wherein the vehicle-side remote controller is a vehicle-mounted intelligent terminal, and a script engine runs on the vehicle-side remote controller; the vehicle-end remote controller comprises the steps: A, receiving an upgrade package, wherein a flashing filefor upgrading an ECU and an upgrade script are contained in the upgrade package, and the upgrade script is written in advance according to flashing specifications of a target ECU; B, analyzing a command in the upgrading script through the script engine, and writing a flashing file into a memory of the target ECU according to the command. The research and development period is shortened, the flexibility is high, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle ECU upgrading, in particular to a method for upgrading a vehicle ECU through a script and a system thereof. Background technique [0002] At present, in the field of automobiles, electrification, intelligence, networking, and sharing have become the new direction and trend of automobile development. The functions of vehicle ECU (Electronic Control Unit, electronic control unit) are becoming more and more powerful, and the time for vehicle development is getting shorter and faster. With the increasing pressure, ECU firmware upgrades and iterations have become the core needs of OEMs, as well as the key tasks of after-sales maintenance. [0003] Since the development of the upgrade function of the vehicle ECU can only be carried out after the design and development of the whole vehicle is completed, that is, the development of the ECU upgrade function can only be carried out on the vehicle end after ...
