Abstract

The invention discloses a differential packet generation method and device, relates to the technical field of system upgrading, and can solve the problems that the ECU differential packet making process is dispersed and the ECU differential packet making efficiency is low. The method mainly comprises the following steps: obtaining an original packet; obtaining a difference tool matched with the original packet under the condition that the original packet supports difference; and performing differential extraction on the original packet by using the differential tool to generate a differentialpacket.

Description

technical field [0001] The invention relates to the technical field of system upgrading, in particular to a method and device for generating differential packets. Background technique [0002] The car-machine terminal usually has system software and application software initially installed by the car manufacturer. During the process of using these softwares, part of the software may need to upgrade the original version of the software due to loopholes not found in the research and development process or in order to meet the new needs of the owners. [0003] At present, the upgrade of the software on the vehicle terminal usually adopts an Over the Air Technology (TOA for short) differential packet upgrade method. Since different automobile manufacturers use different Electronic Control Unit (ECU) differential tools to make upgraded differential packages, vehicle testers need to master the use of different ECU differential tools, and the ECU differential package manufacturing...
