Abstract

The embodiment of the invention provides an ECU flashing method and system and a related device, which are used for improving the safety of ECU flashing. The method comprises: acquiring a verificationfile and an ECU data encryption file, the verification file being generated through encryption of a bound vehicle-mounted device serial number; decrypting the verification file to obtain a bound vehicle-mounted device serial number; judging whether the bound serial number of the vehicle-mounted device is consistent with the serial number of the currently connected vehicle-mounted device or not, if yes, flashing the corresponding ECU according to the ECU data encryption file, and if not, refusing to flash the corresponding ECU.

Description

technical field [0001] The present application relates to the field of automobile diagnosis, in particular to an ECU flashing method, system and related equipment. Background technique [0002] ECU flashing, also known as ECU filling, its basic principle is: the external data flashing tool sends data information to the ECU through the ECU communication network (mostly K-line and CAN bus), so as to realize the management and update of ECU data . [0003] In the existing ECU flashing mechanism, any device can flash the ECU. If the ECU data is illegally flashed, there is a security risk. [0004] In view of this, it is necessary to propose a new ECU flashing method. Contents of the invention [0005] Embodiments of the present application provide an ECU flashing method, system and related equipment, which are used to improve the security of ECU flashing. [0006] The first aspect of the embodiment of the present application provides an ECU flashing method, which is charact...
