Vehicle, vehicle-mounted equipment, OTA file server and upgrading method of OTA file server

Abstract

The invention provides a vehicle, vehicle-mounted equipment, an OTA file server and an upgrading method of the OTA file server. The vehicle-mounted equipment comprises a vehicle-mounted processor anda wireless communication module, the vehicle-mounted processor inquires OTA upgrade package information corresponding to the upgrade version, and obtains a first downloading path of the split public data and a second downloading path of the difference data, and the wireless communication module is used for downloading the public data from the CDN service network pointed by the first downloading path through the CDN acceleration channel, downloading the difference data through the second downloading path, synthesizing the public data and the difference data by adopting a predetermined algorithmto obtain an OTA upgrade package corresponding to the OTA upgrade package information, and upgrading the OTA upgrade package. According to the application, a CDN acceleration scheme can be supportedtechnically, OTA personalized upgrade package upgrade is supported, the cloud encryption and decryption operation resource overhead is reduced, the network traffic overhead of a user is reduced, and the storage and traffic requirements on the CDN of the cloud can also be reduced.

Description

technical field [0001] The present application relates to the field of OTA (Over The Air) upgrade technology, and specifically relates to an in-vehicle device, an OTA file server, an upgrade method based on CDN acceleration, and a vehicle to which the in-vehicle device is applied. Background technique [0002] Content Delivery Network (CDN), by placing caching servers all over the network, builds a layer of intelligent virtual network on the basis of the existing Internet, and publishes the content of the website to the "edge" of the network closest to the user. So that users can get the content they need nearby, so as to alleviate the network congestion and improve the response speed of the website. [0003] Content distribution network is a strategically deployed overall system, including four requirements of distributed storage, load balancing, network request redirection and content management, while content management and global network traffic management are the core o...

Problems solved by technology

This method requires that an encrypted upgrade package be made separately for each user. When the upgrade package is relatively large, the computing power requirements of the cloud and the terminal are very high, and the calculation time is long, and it consumes a huge amount of network traffic to transmit the upgrade package; The upgrade packages are different. If you want to combine CDN acceleration, you need to upload each user’s upgrade package to the CND platform every time. The traffic consumption is huge and the cost is huge.

Therefore, under normal circumstances, only the same upgrade package can be provided for each user, or only differentiated upgrade package upgrade services can be provided for relatively small upgrade packages, and CDN services often have to be passively given up
