The invention provides a remote upgrading method for an electric vehicle controller. The remote upgrading method comprises the following steps that a basic data platform obtains an upgrading file andcreates an upgrading task according to the upgrading file; the basic data platform sends an upgrading instruction to a vehicle-mounted terminal of the to-be-upgraded vehicle according to the upgradingtask; when the vehicle-mounted terminal is allowed to be upgraded, the basic data platform issues an upgrading file to the vehicle-mounted terminal according to the upgrading instruction; after the vehicle-mounted terminal receives the upgrading file, the upgrading file is sent to a target controller of the to-be-upgraded vehicle; and after the target controller receives the upgrading file, the vehicle-mounted terminal controls the target controller to automatically run and upgrade according to the upgrading file. The invention further provides a remote upgrading system of the electric automobile controller. According to the remote upgrading method and the system for the electric vehicle controller, remote transmission of the upgrading file is achieved, the problem that upgrading and updating of the electric vehicle controller are inconvenient is solved, safety and reliability are improved, and operation and maintenance cost is reduced.
Description
【Technical field】 [0001] The invention relates to the technical field of electric vehicles, in particular to a remote upgrade method and system for a controller of an electric vehicle. 【Background technique】 [0002] At present, the electronic equipment used in automobiles is becoming more and more extensive, and the whole vehicle needs a large number of electronic control units to control various executive components, which is more obvious in the field of electric vehicles. The structure of most electric vehicle control systems adopts a distributed layout. The vehicle controller controls the controllers of each component through the Controller Area Network (CAN). With the continuous development of technical requirements, the controller needs to be upgraded. . When multiple controllers of the vehicle need to be upgraded or program adjusted, the vehicle manufacturer or component manufacturer needs to update the program of the controller through a special host computer, and t...
