Abstract

The invention discloses a flashing method and device of an electronic control unit (ECU), diagnosis equipment and a storage medium, is applied to the technical field of automobiles, and is used for solving the technical problems that the flashing method of the ECU is not intelligent enough and low in efficiency in the prior art. The flashing method of the electronic control unit ECU comprises thesteps: obtaining a first flashing parameter of an engine controlled by the electronic control unit ECU; reading and storing the value of the adjustable parameter of the ECU; downloading a corresponding flashing file from a server according to a pre-stored mapping relationship between the first flashing parameter and the flashing file; writing the downloaded flashing file into the ECU; and restoring the stored value of the adjustable parameter of the electronic control unit ECU to the electronic control unit ECU.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a flashing method, device, diagnostic equipment and storage medium of an electronic control unit ECU. Background technique [0002] Electronic control unit ECU, also known as "driving computer", "vehicle computer", etc., is a special microcomputer controller for automobiles. It is an important part of the car, controlling the normal operation of the engine and ensuring the normal operation of the vehicle. When the program in the electronic control unit ECU needs to be updated during vehicle maintenance, or some engine parameters have problems and cannot be modified, it is necessary to flash the program stored in the electronic control unit ECU. [0003] Usually the newly purchased electronic control unit ECU does not write the control parameters, which requires the engine power parameters and configuration parameters to be written into the electronic control unit ECU, so that...
