Vehicle-mounted system software upgrade method, vehicle-mounted system and software server

Abstract

The invention provides a software upgrade method for a vehicle-mounted system. The software upgrade method for the vehicle-mounted system comprises the following steps that: the vehicle-mounted system transmits software upgrade request information to a software server, wherein the software upgrade request information comprises current software version information; the software server acquires a corresponding current software package according to the current software version information, generates a differentiated upgrade package according to the current software package and the upgrade software package, and transmits the differentiated upgrade package to the vehicle-mounted system; and the vehicle-mounted system receives the differentiated upgrade package, verifies the differentiated upgrade package, and upgrades software according to the differentiated upgrade package after successful verification. Through the technical scheme of the invention, the upgrade demands of different versions of all vehicle-mounted software can be met. Meanwhile, the differentiated upgrade packages are generated automatically specific to different versions, so that the downloading traffic is saved, and the downloading time is shortened.

Description

technical field [0001] The invention relates to the electronic field, in particular to a vehicle system software upgrading method, a vehicle system and a software server. Background technique [0002] T-Box is a very important component in today's connected car in-vehicle system, and its main function is to realize the interconnection between cars and TSP. Usually, T-Box is directly assembled into the interior of the vehicle by the production line workers when the car is produced in the car factory, and it is physically isolated from the outside of the vehicle. Because T-Box is equipped with an OTA (Over-the-air, refers to air or wireless technology) module, when car sales companies and 4S stores want to upgrade and maintain T-Box software, they must complete the upgrade command confirmation through the operation interface of the car machine After that, T-Box will download the upgrade package through OTA and then upgrade itself to realize T-Box upgrade and maintenance.
