Automobile bus communication method and system, remote terminal and automobile diagnosis device

Abstract

The invention provides an automobile bus communication method and system for a remote terminal, the remote terminal, an automobile bus communication method and system for an automobile diagnosis device, the automobile diagnosis device and a computer readable storage medium. The automobile bus communication method for the remote terminal comprises the steps of sending the diagnosis data to a server, so that the server sends the diagnosis data to automobile diagnosis equipment, and the automobile diagnosis equipment collects feedback information according to the diagnosis data; starting timing from the time when the diagnostic data is sent, and taking the current time as a sending time after a preset time length is reached; receiving the feedback information sent by the server, wherein the feedback information is sent to the server by the automobile diagnosis device. According to the automobile bus communication method applied to the remote terminal provided by the invention, the real-time problem of remote communication is solved through a pre-delay mechanism, the remote direct troubleshooting is realized, a problem point is immediately captured, the research and development efficiency is improved, and the business trip cost and the time are reduced.

Description

technical field [0001] The present invention relates to the field of automobile CAN bus technology, in particular, to an automobile bus communication method, an automobile bus communication system, a remote terminal, another automobile bus communication method, another automobile bus communication system, a A vehicle diagnostic device and a computer-readable storage medium. Background technique [0002] The development of the modern automobile industry has introduced the automotive CAN (Controller Area Network) bus technology, which satisfies the automotive distributed system-level communication, and at the same time establishes the functions of automotive bus communication, diagnosis and refresh. Has been widely used. [0003] However, as the engineering research and development speed of Hyundai Motor continues to accelerate, the development cycle of a new model has been almost cut in half, which brings challenges to the development of the controller ECU (Electronic Contro...

AI Technical Summary

Problems solved by technology

[0003] However, with the acceleration of engineering research and development of modern automobiles, the development cycle of a new model has been cut in half, which brings challenges to the development of controller ECU (Electronic Control Unit, electronic control unit)

At present, the traditional technology is based on "on-site" troubleshooting in the vehicle or on the bench. If there is a problem during the vehicle test process, the supplier must go directly to the site such as (R&D center, road test base, production line, 4S shop) ), even if you rush to the scene, the problem may not be reproduced again

The time to go to the scene greatly prolongs the time to solve the problem, and it is often impossible to capture the sporadic problems

[0004] Automotive bus communication has a set of very strict time rules. If the near-field communication technologies such as USB and Wifi are used directly through VCI equipment on site, the real-time requirements can be met, but if remote communication is performed, such as through 2G / 3G / 4G network transmission, The existing protocol will always have a delay in air forwarding time, resulting in communication timeout or failing to meet the real-time requirements of automotive on-site diagnosis
