Problems solved by technology
[0003] The existing cloud platform one-to-one upgrade solution has high bandwidth pressure, low upgrade efficiency, and high traffic consumption
In the V2X network, even if the upgrade process can be completed with the help of roadside infrastructure, the network coverage is limited, and the infrastructure construction costs are too high to achieve wide-scale use. When the terminal moves out of the coverage area, the upgrade process will be interrupted. Affect the upgrade efficiency of the vehicle terminal, thereby affecting the user experience

The invention discloses a software version upgrading method and system of a terminal and a vehicle. The method comprises the following steps: acquiring a network bandwidth and software information of a cloud platform; acquiring software information of each terminal in communication connection with the cloud platform; after determining whether the software of each terminal needs data upgrading, determining an upgrading data packet required by each terminal according to the software information of the cloud platform and the software information of each terminal; judging whether the network bandwidth of the cloud platform is lower than a first threshold value or not; if yes, acquiring connectivity information of each terminal in communication connection with the cloud platform; determining a first terminal according to the network bandwidth of the cloud platform and the connectivity information of each terminal in communication connection with the cloud platform; the cloud platform sends the upgrading data packets required by the first terminals to the first terminals; each first terminal sends the upgrade data packet to each neighbor terminal in communication connection with the first terminal, and / or obtains the upgrade data packet provided by each neighbor terminal; and each terminal upgrades the software version according to the upgrade data packet, so that the overall software upgrade efficiency can be improved.
Description
technical field [0001] The present invention relates to the technical field of software upgrades of vehicle-mounted terminals, in particular to a method, system and vehicle for software version upgrades of terminals. Background technique [0002] In order to improve the performance of the vehicle-mounted terminal, it is usually necessary to perform irregular data upgrades on the software of the vehicle-mounted terminal. When the version of the vehicle-mounted terminal software is upgraded, it is generally a one-to-one upgrade of a certain terminal directly through the cloud platform. [0003] The existing cloud platform one-to-one upgrade solution has high bandwidth pressure, low upgrade efficiency, and high traffic consumption. In the V2X network, even if the upgrade process can be completed with the help of roadside infrastructure, the network coverage is limited, and the construction cost of the infrastructure is too high to achieve wide-scale use. When the terminal moves...
