And simultaneously deleting the current data block to be refreshed when the diagnostic service tool receives the next data block to be refreshed.

On the basis of the embodiment, after traversing the data block to be flashed, the server feeds back the completion information of the data block to be flashed to the diagnostic service tool; and the diagnostic service tool generates an ECU data flashing completion prompt according to the completion information.

It can be understood that the completion information of the data block to be refreshed is that the diagnostic service tool has completed the refresh operation on all the data blocks to be refreshed, that is, the current refresh of the ECU to be refreshed is completed, so as to ensure the subsequent upgrade of the ECU,

S220, decomposing the ECU data to be flashed into at least one data block to be flashed according to a partition structure of the vehicle ECU, and sequentially sending the at least one data block to be flashed to the diagnostic service tool.

Specifically, decomposing the ECU data to be flashed into at least one data block to be flashed according to a partition structure of the vehicle ECU includes: the server decomposes the ECU data to be flashed into at least one data block to be flashed according to a partition structure of the vehicle ECU; or decomposing the ECU data to be flashed into at least one data block to be flashed according to a partition structure of the vehicle ECU and uploading the data block to the server.

In the embodiment, the ECU data file stored in the server is cut into blocks according to the partition structure of the vehicle ECU, and the next part of data is downloaded and written in a flash mode after one part of data is written in a flash mode, namely, each data block to be written in a flash mode is written in a flash mode at one time, so that the data cannot be obtained in the whole mode, the ECU data are effectively protected and cannot be obtained by people with other intentions, the risk of divulgence during ECU data flash is effectively reduced, and the safety of the ECU data is improved.

And S230, the diagnostic service tool performs flash writing on the received current data block to be flashed.

S240, judging whether the diagnosis service tool successfully writes the current data block to be written, if so, executing the step S250, and if not, executing the step S260.

And S250, the diagnosis service tool returns the brushing success identification of the current data block to be brushed, after the server verifies the brushing success identification, the server sends the next data block to be brushed to the diagnosis service tool, and the step S270 is executed.

And S260, repeatedly brushing the current data block to be brushed by the diagnostic service tool until the current data block to be brushed is successfully brushed, and executing the step S250.

Specifically, since the ECU data is cut into blocks according to the partition structure logic of the vehicle ECU, after a certain part of data blocks fail to be refreshed (namely, the current data blocks to be refreshed fail to be refreshed), the repeated refreshing of a single data block can be performed, namely, the current data blocks to be refreshed are repeatedly refreshed, the refreshing of the whole ECU storage area is not needed to be performed again like the refreshing of the whole ECU storage area before, and the ECU data refreshing time is greatly saved.

And S270, the diagnostic service tool performs flash writing on all data blocks to be flashed.

And S280, after the diagnostic service tool traverses the data block to be refreshed, feeding back the completion information of the data block to be refreshed to the diagnostic service tool through the server.
