Abstract

The invention provides an automobile electronic control unit ECU flashing method and an automobile electronic control unit ECU flashing device, which are applied to an upper computer. The automobile electronic control unit ECU flashing method comprises the steps of: acquiring a configuration file which is required for flashing a plurality of ECU and configured for the upper computer by a finished automobile management computer, wherein the configuration file comprises data to be flashed into each ECU and auxiliary data used for flashing each ECU; verifying ECU flashing permission of the upper computer; and performing batch flashing on the plurality of ECU connected with the upper computer according to the configuration file when the verification on the ECU flashing permission of the upper computer passes. The automobile electronic control unit ECU flashing method and the automobile electronic control unit ECU flashing device can utilize various kinds of CAN card tools to complete ECU batch flashing of different automobile models, different flashing process and different file format application programs, and the batch flashing can be conducted on the same network segment or different segments in sequence.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a method and device for flashing an electronic control unit (ECU) of an automobile. Background technique [0002] The traditional program file is the source file in s19 / hex format. If it is directly released to the brush writer, the brush writer needs to know a lot of additional information including security algorithm, flash communication rate, communication diagnosis ID, flash channel, etc., which will increase the number of brush writers. The use threshold of the operation, and the traditional flashing tool is generally only developed for one CAN card, which cannot support multiple CAN cards at the same time, which is too limited and not flexible enough; the flashing data transmission process of the traditional flashing tool is fixed in the current software, even if it is updated The process can only be executed with the current process. Once the data process is inconsistent or a sp...
