Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing.

[0023] The present invention is a method and a device for improving the distribution speed and reducing the download storage space during the process of downloading the upgrade package from the cloud to the vehicle end and distributing it to each upgrade node of the vehicle.

[0024] Such as figure 1 As shown, the processing modules included in the device of the present invention are:

[0025] Queue generation module 1, when the OTA client detects that the server has a new version, generates a download deployment queue for each upgrade task to upgrade the target node.

[0026] The download function module 2 downloads the upgrade files of each node in the queue sequentially according to the download deployment queue of the upgrade task.

[0027] The distribution function module 3 distributes the upgrade file to the nodes in the download deployment queue that have downloade...

Abstract

The invention discloses a whole vehicle OTA data downloading deployment method and device. The invention aims to provide a whole vehicle data downloading deployment method and device. The method comprising the following steps: 1, generating a queue; step 2, carrying out serial downloading; step 3, performing storage space comparison; 4, performing parallel distribution; and 5, downloading the file. In the process that the vehicle machine or the T-BOX downloads the upgrading file from the server and distributes the upgrading file to each upgrading node, through mutual coordination and parallel execution of the downloading and distributing processes, the requirement for the storage space of the upgrading file of the vehicle machine or the T-BOX is reduced; and meanwhile, the overall time for downloading and distributing the upgrade file can be shortened.

Description

technical field [0001] The invention belongs to automobile software technology, and in particular relates to a method and technology for remote upgrading of automobile software. Background technique [0002] OTA refers to over-the-air download technology, which realizes remote management of software through the interface of mobile communication. OTA is a channel for car software upgrades, and its value is to remotely flash new software into cars. The controller with mobile communication capabilities at the vehicle end is usually the vehicle or T-BOX. During the OTA process of the vehicle, the client of the vehicle or T-BOX first needs to establish a connection with the server and download the upgrade file to the local, and then download the The upgrade file is distributed through the vehicle network to each upgrade node that executes software flashing. With the increase of intelligent controllers with self-upgrade capability in the whole vehicle, the size of the downloaded ...
