Embodiment Construction

[0022] The technical problem to be solved by the present invention is: car factories, automobile 4S stores and automobile diagnostic instrument suppliers mostly use hand-held diagnostic instruments to diagnose automobiles. When locating automobile faults, it is necessary to carry diagnostic instrument equipment for on-site operation, which is inconvenient. It is also not suitable for the diagnosis of multiple vehicle models, and it is not suitable for the diagnosis of the owner's own vehicle. The technical idea for solving this technical problem proposed by the present invention is: to propose a client, and make the client communicate with the server, send the vehicle diagnosis trigger start signal to the server through the client, so that the server instructs the vehicle terminal to diagnose the vehicle, So that the user can obtain the car diagnosis data through the client.

Abstract

The invention discloses a remote diagnosis method for a vehicle, and the method comprises the following steps: S1, transmitting a vehicle diagnosis triggering start signal to a server through a client; S2, transmitting a vehicle diagnosis triggering signal to a vehicle-mounted terminal after the server receives the vehicle diagnosis triggering start signal; S3, reading fault codes of a vehicle body electronic control unit one by one after the vehicle-terminal receives the vehicle diagnosis triggering signal, generating vehicle diagnosis raw data through all read fault codes of the vehicle body electronic control unit, transmitting the vehicle diagnosis raw data to the server, and transmitting the vehicle diagnosis raw data to a client after the receiver receives the vehicle diagnosis raw data. The method is simple and practical, and is high in safety.

Description

technical field [0001] The invention relates to the field of automobile diagnosis, in particular to an automobile remote diagnosis method. Background technique [0002] The degree of electronic control of automobiles is regarded as an important indicator to measure the level of modern automobiles, and the higher the degree of electronic control, the more difficult it is to diagnose automobile faults. According to statistics, the time of automobile fault diagnosis accounts for about 70% of the total maintenance time. Troubleshooting time accounts for only about 30% of the total maintenance time. [0003] At the same time, car factories, automobile 4S stores and automobile diagnostic instrument suppliers mostly use hand-held diagnostic instruments to diagnose automobiles. When locating automobile faults, it is necessary to carry diagnostic instrument equipment for on-site operation, which is neither convenient nor suitable for multi-model vehicles. Diagnosis does not apply to...
