Description

Technical Field

[0001] The present application relates to the technical field of automobile fault diagnosis, and in particular to a vehicle diagnosis method and related equipment. Background Art

[0002] Vehicle diagnosis is a key link in modern automobile maintenance and service. With the continuous advancement of automobile electronics, vehicle fault diagnosis has become an important means to ensure the safe operation and maintenance of vehicles. Traditional vehicle diagnosis methods mainly rely on professional technicians to use special tools for manual inspection, which is not only time-consuming and labor-intensive, but also requires a high level of technology. However, with the popularity of smartphones and tablets, more and more on-board diagnostic systems have begun to support operation through mobile devices, which greatly improves the convenience and efficiency of diagnosis.

[0003] In the existing technology, in order to realize the vehicle diagnostic function, the following methods are usually used: 1) Connect the diagnostic instrument to the vehicle through a wired connection (such as the OBD-II interface), and then communicate with the computer or other devices through a USB or serial port. Although this method is stable and reliable, it is complicated to operate and requires professionals to complete; 2) Perform remote diagnosis through a cloud server. This method can realize remote technical support, but requires a stable network environment and there are certain risks in data security.

[0004] Although the above methods have their own advantages, they still have some shortcomings in practical applications. For example, although the wired connection method has high stability, the operation is cumbersome and not suitable for rapid diagnosis; the remote diagnosis method is limited by network conditions and cannot ensure the accuracy of the data. Therefore, how to simplify the operation process and improve the accuracy and efficiency of fault handling is a technical problem that needs to be solved urgently. Summary of the invention

[0005] The purpose of this application is to overcome the above-mentioned technical problems and provide a vehicle diagnosis method and related equipment, which can simplify the operation process and improve the accuracy and efficiency of fault handling.
