Description
Technical field
The present invention relates to car networking field, in particular to a kind of upgrade-system and upgrade method.
Background technique
Automobile has vehicle mass and reliability the requirement of extreme harshness, traditional vapour as high value durable goods
Vehicle is when there are quality problems, it is common practice to and it carries out vehicle and recalls, but recall operation had not only increased depot's operation cost, but also
It makes troubles to user, influences depot's brand and acceptance of the users.On the other hand, with vehicle intellectualized development, Cartronic
Degree is continuously improved, and automobile electronic system is as other consumer electronics systems, and in its life cycle, existing upgrade is needed
It asks, especially software upgrading is even more and frequently occurs.With Development of Wireless Communications, the bandwidth of wireless communication especially cellular communication is not
Disconnected to increase, one kind is come into being by the mode that OTA (Over The Air, remote upgrade) carries out remote software upgrade.
Remote upgrade OTA refers to that terminal software by 4G/5G network, leads in the case where not having to local device wired connection
Cross the function that terminal software or data were downloaded and updated to wireless communication technique.
In recent years, car networking Industry Quick Development, especially in C-V2X (Cellular Vehicle-to-
Everything, car networking based on cellular technology communicate (honeycomb vehicle connection)) after technology occurs, join automobile for intelligent network
Various technical solutions emerge one after another.
V2X refers to that vehicle is a series of general name of vehicle mounted communication technologies to extraneous information exchange.V2X includes automobile to vapour
Vehicle (V2V), automobile to roadside device (V2R), automobile to infrastructure (V2I), automobile to pedestrian (V2P), automobile to locomotive
(V2M) and automobile is to bus (V2T).
In the terminal of V2X (the Vehicle to X) system of carrying, the mode based on the docking of publicly-owned V2X platform can be further
Remote upgrade mode is expanded, expands to 2V, 2I upgrading from traditional 2N upgrading.Upgrade avoidable terminal by V2X multipath do not having
It can not upgrade problem when having network.
Software upgrading is carried out by V2X system, the communication of one side high speed can shorten the time of software package downloading, another party
Face can expand the range of upgrading, when wireless communication network signal is bad, also be able to satisfy customer upgrade demand.
By the upgrading scheme based on V2X system, corresponding V2X OTA service platform is needed.General scheme is will to rise
Grade file downloads to RSU (Road Side Unit, roadside unit) equipment that upgrading vehicle is connected from OTA platform, and vehicle must
Must be in current RSU coverage area, the coverage area of current RSU can just be left by downloading completion up to upgrade file.If
Upgrade file is not downloaded and is finished, and vehicle just has left the coverage area coverage of current RSU, is carried out entering new RSU
When upgrading, upgrade file can only be re-downloaded, poor user experience is caused.
Summary of the invention
In view of this, the embodiment of the present invention provides a kind of upgrade-system and upgrade method, have the upgrade-system based on V2X
There are certain mobility management capabilities, vehicle need not wait in current RSU coverage area, until OTA upgrade file packet has been downloaded
Cheng Caineng leaves the coverage area of current RSU, enhances user experience.
