The invention relates to the technical field of ECU software upgrading, and provides a system and method for realizing the ECU software OTA function of a new energy electric vehicle. The method comprises the following steps of using an OEM background management system to searche a VIN code list of a vehicle to be upgraded; using the OTA management system to configure the task list based on the VINcode list, check whether the software version of the target controller of each vehicle to be upgraded is consistent with the target software version of the target controller, if the software versionis inconsistent, using the OTA management system to make the upgraded software package and distribute it to the corresponding vehicle to be upgraded; when the upgrade time is reached, using the OTA management system to send a vehicle condition detection command to the corresponding OTA front end; 5 using the front end of the OTA to detect whether the current state of the vehicle meets the upgrading requirements based on the vehicle state detection instruction; 6, if that detection result is yes, using the OTA management system to issue an upgrade instruction to the OTA front end of the corresponding vehicle; S7 using the OTA front end to upgrade the software of the target controller based on the upgrade instruction. The method upgrades the software of the target controller uniformly on each vehicle type without upgrading each vehicle.
Description
technical field [0001] The invention relates to the technical field of ECU software upgrade, and provides a system and method for realizing the OTA function of ECU software of a new energy electric vehicle. Background technique [0002] With the development of social economy and my country's strong support for new energy electric vehicles, new energy electric vehicles are gradually entering thousands of households and becoming an indispensable means of daily travel. [0003] In the early stage of electric vehicle development, each ECU is in the stage of gradual improvement. The update cycle is short and the number of times is high. The engineers of each ECU need to spend a lot of time to upgrade each ECU. After the production of electric vehicles is completed, the software upgrade of ECU will become The challenges faced by after-sales engineers. Contents of the invention [0004] The invention provides a method for realizing the OTA function of the ECU software of a new e...
