Abstract

The present application provides a vehicle ECU flashing method, device, vehicle ECU and storage medium, which relate to the field of vehicle technology, can effectively reduce the time for flashing ECU data, and improve the efficiency of flashing ECU data. The method includes: obtaining the data to be flashed; decomposing the data to be flashed into a preset number of data blocks to be flashed according to the communication protocol type of the vehicle ECU; respectively compressing each of the data blocks to be flashed to obtain Compressing the data block; generating first instructions for flashing each of the compressed data blocks according to the communication protocol type of the vehicle ECU; sending the first instruction to the vehicle ECU, and the first instruction is used for Instructing the vehicle ECU to decompress each of the compressed data blocks, and write the decompressed data into preset storage addresses of the vehicle ECU respectively.

Description

technical field [0001] The present application relates to the field of vehicle technology, and in particular to a vehicle ECU flashing method, device, vehicle ECU and storage medium. Background technique [0002] With the continuous development of vehicle technology, electronic control units (Electronic Control Unit, ECU) have been widely used in vehicles. For example, the ECU plays a decisive role in improving the power and safety of the vehicle, but as the function of the ECU becomes more and more powerful, the process of flashing the data of the ECU in the process of vehicle diagnosis becomes more and more complicated. [0003] At present, the commonly used data flashing method is to read the original flashing data, and according to the format of the automobile communication protocol, the original flashing data is decomposed into data frames, and then sent to the ECU for flashing. This flashing method has the problem of low flashing efficiency when more and more data is ...
