Problems solved by technology

Most of the diagnostic communication tools used in traditional ECU refresh are hand-held diagnostic devices. The equipment is expensive and professional. When using it to upgrade ECU, it usually takes back the factory area for refresh or sends engineers to the site to refresh the data. , these two methods will bring a lot of cost problems. At the same time, due to the long period of data refresh, it will inevitably lead to a decline in customer satisfaction, so it is not suitable for promotion and use.

Abstract

The invention discloses an ECU data safety upgrading system, which is characterized by comprising an encrypted file generating module, a user management module and an upgrading module, wherein the encrypted file generating module is used for generating upgrade information packet files after encrypting ECU data and control information, the user management module dispenses corresponding registration codes according to request codes provided by users for users' right management and after-sale records, the upgrading module utilizes a USB softdog and user information to verify the uses' rights, and then obtains and compares the information of electronic controllers needed to be upgraded with the control information in the upgrade information packets, if meeting requirements, the upgrade information packet files are decrypted, and ECU is upgraded by downloading data within allowable address range. The ECU data safety upgrading system is capable of carrying out ECU upgrading operations through technicians at a service station, and has the advantages of low cost, fast response and easy operation while guaranteeing data safety.

Description

technical field [0001] The invention relates to a system for upgrading ECU data of an engine electronic unit control system, in particular to a system for safely upgrading ECU data. The invention also relates to a method for safely upgrading ECU data. Background technique [0002] With the intensification of competition in the domestic auto industry, major auto companies are launching new cars faster and faster, and the compression of the development cycle has brought the risk of ECU data. And due to various factors, during the car development and after-sales stages, customers will request to refresh the current release data of the ECU. Most of the diagnostic communication tools used in traditional ECU refresh are hand-held diagnostic devices. The equipment is expensive and professional. When using it to upgrade ECU, it usually takes back the factory area for refresh or sends engineers to the site to refresh the data. , these two methods will bring a lot of cost problems. ...
