Vehicle diagnosis protocol obtaining method and device and related equipment thereof

Abstract

The embodiment of the invention discloses a vehicle diagnosis protocol acquisition method, a vehicle diagnosis protocol acquisition device and related equipment, which are used for downloading a corresponding diagnosis protocol according to a diagnosis function selected by a user instead of downloading a whole complete diagnosis protocol packet, so that the time and the flow of downloading the diagnosis protocol are saved, and the vehicle diagnosis efficiency and the user experience are improved. The method comprises the steps that a target configuration list is acquired and displayed, wherein the target configuration list at least comprises ECU configuration information of a target vehicle type and diagnosis function configuration information; obtaining at least one target diagnosis function selected by a user based on the target configuration list, and forming diagnosis demand information; sending the diagnosis demand information to a server, and receiving a target diagnosis protocol packet returned by the server based on the diagnosis demand information; the target diagnosis protocol packet comprises a diagnosis protocol required for executing the target diagnosis function.

Description

Technical field [0001] The embodiments of this application involve the field of vehicle diagnosis technology, especially the method, device and related equipment of the vehicle diagnostic agreement. Background technique [0002] At present, in the diagnosis of vehicles, each vehicle system generally has a separate and complete diagnostic protocol package, such as the Toyota's vehicle diagnostic agreement package contains all the diagnostic function protocols of all ECUs of Toyota, such as Camry, Corolla, etc. [0003] Because the ECU or diagnostic function of different models in different vehicles is often increased or changed, each customer must download the latest diagnostic protocol package when diagnosing the designated car. The ECU function of the corresponding model is diagnosed. Now that there are more and more models, the number of ECUs and diagnostic functions of each model has also increased significantly, which has caused a large number of diagnostic protocols. The upd...
