Embodiment 1

[0041] An embodiment of the present invention provides a vehicle fault detection and diagnosis method, which is preferably applied to the faulty vehicle side. The faulty vehicle has an automatic diagnosis device, for example, an OBD system, which is used to obtain vehicle fault data in real time. For the specific fault diagnosis process, reference may be made to relevant descriptions in the prior art, which will not be repeated here.

[0042] figure 1 is a flow chart of the vehicle fault detection and diagnosis method, such as figure 1 As shown, the method includes:

[0043] Step 102, collecting the original fault data of the vehicle obtained by the OBD system;

[0044] Step 104, analyzing the original fault data to generate fault information;

[0045]Step 106, sending the fault information to the background fault diagnosis server;

[0046] Step 108, receiving fault diagnosis information fed back by the background fault diagnosis server.

[0047] It can be seen from the a...

Embodiment 2

[0055] The embodiment of the present invention also provides a vehicle fault diagnosis method, which is applied to a background fault diagnosis server, and the background fault diagnosis server is preferably applied to a 4S store side.

[0056] figure 2 is a flow chart of the vehicle fault diagnosis method, such as figure 2 As shown, the method includes:

[0057] Step 202, receiving fault information from the faulty vehicle;

[0058] Step 204, generating fault diagnosis information according to the fault information;

[0059] Step 206, feedback the fault diagnosis information to the faulty vehicle, so that the user can repair the faulty vehicle.

[0060] As can be seen from the above description, through the real-time interaction between the background fault diagnosis server and the faulty vehicle based on fault information, compared with the prior art, the embodiments of the present invention can provide users with effective and timely fault solutions.

[0061] Preferab...

Embodiment 3

[0066] An embodiment of the present invention provides a vehicle fault detection and diagnosis system, image 3 is the block diagram of the vehicle fault detection and diagnosis system, such as image 3 As shown, the system includes: a vehicle fault detection and diagnosis device 1 and a background fault diagnosis server 2 . Among them, the vehicle fault detection and diagnosis device 1 can be located on the vehicle side, preferably used to implement the method in the first embodiment above; the background fault diagnosis server 2 can be located in the 4S shop, preferably used to implement the method in the second embodiment above. The following combination image 3 The vehicle fault detection and diagnosis device 1 and the background fault diagnosis server 2 are described in detail respectively.

[0067] Such as image 3 As shown, the vehicle fault detection and diagnosis device 1 includes:

[0068] The failure information collection unit 10 is used to collect the origina...

Abstract

The invention provides a fault diagnosis server, a method, a device and a system for detecting and diagnosing vehicle faults. The device for detecting and diagnosing vehicle faults comprises a fault information acquisition unit, a fault information generation unit, a fault information transmitting unit, a diagnosis information receiving unit and an information output unit, wherein the fault information acquisition unit is used for acquiring original vehicle fault data from a vehicle-mounted on-line diagnosis system; the fault information generation unit is used for generating fault information after analyzing the original fault data; the fault information transmitting unit is used for transmitting the fault information to the background fault diagnosis server; the diagnosis information receiving unit is used for receiving fault diagnosis information which is fed back by the background fault diagnosis server; and the information output unit is used for outputting the fault information and/or the fault diagnosis information. Through the invention, a user can conveniently receive diagnosis information provided by a 4S shop according to fault information in time, thereby solving vehicle faults.

Description

technical field [0001] The invention relates to the field of vehicle fault processing, in particular to a background fault diagnosis method and server, a vehicle fault detection and diagnosis method, device and system. Background technique [0002] With the development of society, vehicles such as buses, taxis, private cars and trucks have become the main means of transportation at present. During the driving process of the vehicle, it is inevitable that there will be faults. The current methods of vehicle fault self-inspection and diagnosis are as follows. The following are the analysis and description of these methods. [0003] (1) Through the vehicle fault detector [0004] This method can only provide help to users in vehicle fault detection and processing to a certain extent, and its disadvantages are: there are various types of vehicle fault detectors on the market now, and the operation is complicated, and it is difficult for users to choose and use; for novice drive...
