Problems solved by technology

[0005] The purpose of the present invention is to provide a method and system for upgrading the vehicle controller software, and solve the technical problem: the existing OTA upgrade technology does not classify the upgrade object, upgrade the process into segments and separate the upgrade roles, and cannot realize the controller's upgrade. Unified upgrade management, centralized control of the upgrade process, and platformization of OTA technology lead to long upgrade times, abnormal upgrades, and low upgrade efficiency

Embodiment Construction

[0068] The present invention will be further described below in conjunction with the accompanying drawings.

[0069] like figure 1 As shown, it is a system architecture diagram of the present invention. The present invention involves an OTA client, an OTA master and two OTA sub-control nodes that implement different functions. The OTA client communicates with the OTA sub-node where the main chip with the operating system is installed through a deployment protocol. The OTA sub-control where the main chip with the operating system is installed can directly realize the software iteration of the main chip through the operating system, and carry related applications on the operating system. It can also be updated, but the controller without an operating system needs the cooperation of the UDS parallel flashing host computer to realize the software update through the OTA sub-control node.

[0070] The OTA client is also connected to the OTA master node through a deployment protocol...

Abstract

The invention relates to a vehicle control unit software upgrading method and system, and the system comprises: an OTA client side, which collects the version information of a main chip and other controllers, communicates with a server side, obtains upgrading task information from a cloud side, downloads an upgrading package and a rollback package, sends an upgrading state to the cloud side, sends the upgrading state to the server side, and meanwhile, is responsible for a man-machine interaction function; an OTA master control node, wherein the OTA master control node is responsible for checking the installation condition of the whole vehicle, keeping the installation state and executing an installation strategy; and OTA sub-control nodes, wherein the OTA sub-control nodes comprise two types, one type of the OTA sub-control nodes is responsible for controlling the upgrading of the main chip provided with the operating system, and the other type of the OTA sub-control nodes is responsible for controlling the upgrading of other controllers not provided with the operating system. The unified management of the controller, the centralized control of the upgrading process and the platformization of the OTA functional component are realized by classifying the upgrading object, segmenting the upgrading process and separating the upgrading role.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to an upgrade technology of vehicle controller software. Background technique [0002] OTA is a channel for car software upgrade. Its function is to flash the latest version of the upgrade package from the cloud to the car. OTA remote upgrade technology has gradually become the standard configuration of intelligent networked vehicles. Through continuous iteration, the software is continuously updated, thereby driving the automotive industry. A brand new operation and business model, the OTA of the vehicle is limited by the electronic and electrical architecture, and the number of controllers is as many as tens or even hundreds, and the controllers are provided by different suppliers, running a variety of different operating systems and Application software, for example, there are multiple main chips, and each main chip runs a different operating system, and multiple controllers ha...
