Embodiment 1

[0055] This embodiment provides a vehicle diagnostic data flow analysis method, which is executed by a vehicle diagnostic instrument, such as figure 1 ,include:

[0056] S110. Obtaining a vehicle diagnostic data stream from the vehicle under test:

[0057] In this step, detecting and diagnosing the function to be diagnosed may include: the vehicle diagnostic instrument is connected to the on-board diagnostic system of the vehicle to be tested through the diagnostic interface to form a vehicle diagnostic channel. And get the vehicle diagnostic data stream. The data stream is the real-time data of the vehicle acquired by the electronic control unit of the vehicle through sensors, actuators and other components, and changes with time and working conditions. The car maintenance technician can understand the working status of the car through the data stream.

[0058] S120. Group the vehicle diagnostic data stream to generate at least two grouped data.

[0059] In this step, opti...

Embodiment 2

[0076] In this embodiment, on the basis of the above-mentioned embodiments, in the vehicle diagnosis, high-frequency commonly used data are selected for diagnosis according to preset grouping rules, such as image 3 , including the following steps:

[0077] S210. Obtain a vehicle diagnostic data stream from the vehicle under test.

[0078] In this step, detecting and diagnosing the function to be diagnosed may include: the vehicle diagnostic instrument is connected to the on-board diagnostic system of the vehicle to be tested through the diagnostic interface to form a vehicle diagnostic channel. And get the vehicle diagnostic data stream.

[0079] S220. Group the vehicle diagnostic data stream to generate at least two grouped data.

[0080] In an alternative embodiment, when grouping and displaying, the vehicle diagnostic instrument obtains preset grouping rules through a server, and groups the vehicle diagnostic data stream based on the grouping rules to generate at least t...

Embodiment 3

[0095] Such as Figure 4 , the present embodiment provides a vehicle diagnostic data flow analysis system 3, including the following modules:

[0096] An acquisition module 301, configured to acquire vehicle diagnostic data streams from the vehicle under test. The module is also used for: acquiring a selection instruction input by a user; and determining second abnormal data from at least two grouped data based on the selection instruction.

[0097] The grouping module 302 is used for grouping the vehicle diagnostic data flow to generate at least two grouping data; this module is also used for: obtaining a preset grouping rule from the first database of the server; The vehicle diagnostic data stream is grouped to generate at least two grouped data. The module is also used to perform single group display and / or group display function on the grouped data, and divide the data flow display into two ways. You can change the display method according to your preference. The first...

Abstract

The invention provides a vehicle diagnosis data flow analysis method, which is executed by a vehicle diagnosis instrument and comprises the following steps: acquiring a vehicle diagnosis data flow from a to-be-detected vehicle: grouping the vehicle diagnosis data flow to generate at least two grouped data; determining one or more pieces of first abnormal data from the at least two pieces of grouped data; diagnosing the one or more pieces of first abnormal data, and generating one or more first diagnosis results. The invention also provides a sorting method which comprises the following steps: after obtaining the vehicle diagnosis data stream, obtaining a preset single-group sorting rule through the server or receiving a single-group sorting rule input by a user; and sorting the vehicle diagnosis data streams based on the single group sorting rule. According to the method, the data are grouped, and the first abnormal data stream is screened out from the grouped data for diagnosis, so that the diagnosis efficiency is improved. By sorting the data, the abnormal data flow items and the data flow items with high use frequency can be quickly checked, and the diagnosis efficiency is improved.

Description

technical field [0001] Embodiments of the present invention relate to vehicle diagnosis technology, and in particular to a vehicle diagnosis data stream analysis method, system, server and storage medium. Background technique [0002] In recent years, with the rapid development of the automobile industry and the rapid development of automobile technology, automobiles are equipped with many electronic control units to increase the comfort, ease of operation and safety of automobiles. With the use of these high-precision control units, the threshold for car maintenance is getting higher and higher. In this context, it is necessary to use special equipment to read relevant information from the control unit when performing maintenance operations on the car, so various car diagnostic equipment has emerged as the times require. [0003] In the current diagnostic equipment, the data stream display does not highlight the existence of abnormal data stream items. According to the abo...
