OTA software version management method based on block chain technology

Abstract

The invention relates to an OTA software version management method for an intelligent networked vehicle. The OTA software version management method comprises the following steps: S1, acquiring a version information table of a software body of a vehicle model; s2, building a vehicle model software stack block chain framework and a vehicle software stack block chain framework; s3, establishing a block chain initial block of the vehicle model software stack and a block chain initial block of the vehicle software stack; s4, acquiring an updating action of the software stack of the vehicle model, constructing a vehicle model software stack change data table, pushing the data table into the blockchain of the vehicle model software stack, acquiring an updating action of the software stack in thevehicle, constructing a vehicle software stack change data table, and pushing the data table into the blockchain of the vehicle software stack; and S5, adjusting a software relationship in the vehicle. Compared with the prior art, the method has the advantages that software stacks of vehicle types and vehicles are subjected to refined management, the functional integrity of the vehicles after software upgrading and addition or deletion is guaranteed, OTA cooperation of multi-party software management platforms (vehicle enterprises, accessory factories and application software stores) is supported, and the OTA of the whole vehicle full-software stacks in the true sense is achieved.

Description

technical field [0001] The invention relates to a software version management method of an intelligent networked vehicle OTA (On The Air, upgrade over the air) platform, in particular to a blockchain technology-based OTA software version management method. Background technique [0002] At present, intelligent networked vehicles generally support OTA (On the Air, software upgrade over the air) function. Through OTA, car manufacturers can timely push new software versions online to achieve the purpose of improving vehicle performance, adding vehicle functions or repairing vehicle defects. [0003] The key to realizing OTA is to completely synchronize the management of vehicle-side and platform-side software. The car side manages the upgradeable software collection version information of the car, the platform side manages all upgradeable software collections, and the platform side pushes the name of the software collection to be upgraded according to the upgradeable software co...

Problems solved by technology

[0014] The purpose of the present invention is to provide a method to overcome the defects in the above-mentioned prior art that the available software stack and its version changes in the whole life cycle of each model and a single vehicle cannot be finely managed, and that it does not support separate management and operation of software.
