Abstract

The invention relates to a control method for software upgrading and failure rollback of hydrogen energy automobile controller, and belongs to the technical field of automobiles. The control method comprises the steps that upgrading push updating of automobile controller software is obtained, the upgrading software is downloaded and verified, whole automobile controller partition information and current version software information are obtained and sent to a remote server, upgrading flashing service is started, and the whole automobile controller responds to the flashing service to upgrade thesoftware; and the vehicle control unit finishes upgrading and feeds back an upgrading result, and if the Internet of Vehicles terminal receives upgrading failure information, a next upgrading failurerollback mechanism is entered: the vehicle control unit recovers the vehicle control unit software to version software before upgrading through a vehicle flashing technology. According to the controlmethod, the phenomenon that the automobile cannot be started due to failure of the automobile controller software in the upgrading process can be effectively avoided. The automobile using experienceof a user is improved, and both the cost and the time are saved.
