Embodiment Construction

[0052] The embodiment of the present invention solves the technical problem of low OTA online upgrade efficiency in a traditional automotive software online upgrade system in a weak network environment by providing an online automotive software upgrade system and method based on the QUIC protocol.

[0053] In order to better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0054] First of all, the term "and / or" appearing in this article is just a kind of relationship describing the relationship between related objects, which means that there can be three kinds of relationships, for example, A and / or B, which can mean: there is A alone, and A exists at the same time and B, there are three cases of B alone. In addition, the character " / " in this article generally indicates that the contextual objects are an "or" re...

Abstract

The invention discloses an automobile software online upgrading system and method based on a QUIC protocol, and relates to the technical field of vehicle networks. After the OTA cloud detects that the automobile software needs to be updated, the OTA cloud pushes a manufactured differential packet to a CDN (Content Delivery Network) server; the QUIC proxy server subscribes to the CDN server, the CDN server synchronously pushes the differential packet to the QUIC proxy server subscribing to the CDN server after receiving the differential packet, and the QUIC proxy server synchronizes the differential packet pushed by the CDN server; after the client side receives the software updating notification, whether the current network environment is a weak network or not is judged, if the current network environment is the weak network, the client side can establish QUIC connection with the QUIC proxy server, and the QUIC proxy server can send the differential packet to the client side through the QUIC protocol for software upgrading, so that the OTA online upgrading efficiency can be improved in the weak network environment.

Description

technical field [0001] The invention relates to the technical field of the Internet of Vehicles, in particular to a QUIC protocol-based online vehicle software upgrade system and method. Background technique [0002] At present, most of the cars realize the update and upgrade of the car control system software through OTA (Over the Air Technology) online upgrade method, and the update and upgrade of the car control system software can be realized in any place with a network, without the need for the user to update the car Drive to the 4S store for upgrades. [0003] OTA online upgrade usually stores the upgrade differential package in the OTA cloud on a CDN (ContentDeliveryNetwork, Content Delivery Network) server for acceleration. CDN is a content distribution network built on the Internet. Relying on servers deployed in various places and through the load balancing and content distribution scheduling of the central platform, users can obtain the required content nearby, w...
