Abstract

The invention discloses an engine ECU flashing method, device and system. The method comprises the steps that engine data of a to-be-flashed vehicle are obtained; after project maintenance data are called according to the engine data, the project maintenance data are sent to the automatic calibration device, so that the automatic calibration device obtains configuration data according to the project maintenance data; and configuration data sent by the automatic calibration device are received, ECU code data are invoked according to the configuration data, and the ECU code data are sent to the automatic calibration device, so that the automatic calibration device flashes the engine ECU of the vehicle to be flashed according to the ECU code data. According to the embodiment of the invention, the data maintenance cost can be reduced, and the flashing safety of the ECU of the engine can be improved.

Description

technical field [0001] The invention relates to the technical field of data flashing, in particular to a method, device and system for flashing an engine ECU. Background technique [0002] With the rapid development of the automobile industry, people have higher and higher requirements on the performance of automobiles. In order to maximize the engine control performance, the mechanical control of the engine has gradually been replaced by electronic control. Due to the vigorous development of various types of control systems, facing the diverse needs of customers, for the core of engine electronic control technology - ECU (Electronic Control Unit) electronic control unit, it is necessary to ensure the safety, reliability, efficiency and adaptability of calibration data. Make higher demands. [0003] However, the engine ECU flashing system in the prior art does not uniformly manage the ECU code data of different manufacturers and different systems, resulting in the risk that...
