Abstract

The present invention provides a data flashing method, device, equipment and computer-readable storage medium. The method includes: determining the parameters to be flashed for each controller to be flashed, and the parameters to be flashed include each of the controllers to be flashed The communication baud rate of the network segment where the controller is located and the data memory to be flashed corresponding to the controller to be flashed; determine each A flashing priority of the controller to be flashed; performing data flashing on the controller to be flashed according to the flashing priority. Thus, the flashing time can be improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data flashing method, device, equipment and computer-readable storage medium. Background technique [0002] Electronic Control Unit (ECU for short), also known as "driving computer", "vehicle computer" and so on. In terms of use, it is a special microcomputer controller for automobiles. ECU data flashing, also known as flashing ECU, flashing car computer board, and controller flashing, has three main applications: one is to encapsulate data when the engine / car is off the assembly line, and the other is to update and repair the ECU at the car repair station. The third is the application of engine modification. When updating and repairing the ECU, it is generally necessary to flash the data of the controller through a diagnostic instrument. [0003] Controller data can be divided into multiple data areas according to the different nature of control tasks, such as parts inform...
