Embodiment 1

[0048] figure 1 It is a schematic diagram of an application scenario of a data update system provided by an embodiment of the present invention. The system includes: at least one data update device and at least one server, and the server stores update files corresponding to multiple vehicle models. The application scenario is not limited to the application scenario of the system. The system includes at least one server, at least one data update device, and a plurality of ECU systems of automobiles, wherein the data update device can be an automobile diagnostic device, and the update method is specific. For: when the car ECU system needs data update, the car user can go to the place with the data update device, and the user can obtain the system data of various models stored in the server through the data update device, and obtain the file data matching their own models. , and then update the ECU data of the car through the data update device.

Abstract

The present invention is applicable to the field of automotive electronics and provides a data updating method. The method includes: receiving an instruction for obtaining an update file corresponding to a predetermined model, sending a predetermined model update file obtaining command to a server, so that the server, according to the command, Matching the update file corresponding to the predetermined model with the update file corresponding to the plurality of pre-stored models, and sending the updated file corresponding to the found predetermined model to the data updating apparatus, and the data updating apparatus determines, according to the acquired Of the predetermined model corresponding to the update file to update the ECU data of the vehicle. The method sends the system data of different vehicle models to the server for backup. When the automobile users need to update a certain data or some data of its own system, the method can obtain the corresponding updated data directly from the server, which is convenient and quick without the need of And then through the car brand service agencies or other specialized auto service agencies to be updated.

Description

technical field [0001] The invention belongs to the technical field of automotive electronics, and in particular relates to a data update method, device, system and server. Background technique [0002] With the improvement of people's living standards, automobiles have gradually become a necessity in people's daily life. However, in the process of automobile maintenance, updating the software of ECU (Electronic Control Unit, electronic control unit) has become an important task, because Whether the ECU software runs normally or not directly affects the performance of the car. [0003] At present, the usual update method is to obtain the original factory data package through the car manufacturer, and update it by the original factory data package. However, this method of updating through the original factory package requires the car manufacturer to obtain the relevant data. The model requirements are relatively strict, and the operation is troublesome and the cost is high. ...
