[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] When diagnosing vehicle faults, the automobile diagnostic equipment can read the current fault code information, and the maintenance technician usually formulates a vehicle maintenance plan based on the fault code. The maintenance technician may not be aware of the vehicle's original maintenance history, and the vehicle maintenance efficiency will be relatively low. Therefore, this application will specifically introduce a vehicle fault diagnosis method, which can improve the efficiency of vehicle fault diagnosis to a certain extent.

[0037] See also Figure 1 As shown, the embodiment of the present application discloses a vehicle fault diagnosis method, comprising:

[0038] Step S11: reading the current fault code information and regional location information of the target faulty vehicle through the vehicle diagnostic equipment, and determining whether the user of the vehicle diagnostic equipment has the preset fault viewing authority for the target faulty vehicle.

[0039] In this embodiment, the current fault code information and regional location information of the target fault vehicle are read through the vehicle diagnostic device, including: reading the vehicle characteristic information of the target fault vehicle through the vehicle diagnostic device, and determining the current fault code information of the target fault vehicle based on the unique vehicle identification code corresponding to the target fault vehicle and the fault code corresponding to the vehicle characteristic information; obtaining the regional location information uploaded by the target fault vehicle. Each time a vehicle diagnosis is performed, the vehicle maintenance personnel will read the vehicle fault code information through the vehicle diagnostic device. Specifically, the vehicle characteristic information of the target fault vehicle is read through the vehicle diagnostic device, wherein the vehicle characteristic information includes but is not limited to vehicle manufacturer, model, year and other vehicle characteristic information, and then the current fault code information of the target fault vehicle is determined based on the fault code corresponding to the vehicle characteristic information, and the regional location information of the target fault vehicle is obtained through the positioning device of the target fault vehicle. In a specific embodiment, each time a vehicle maintenance diagnosis is performed, the current fault code information of the target fault vehicle is determined from the vehicle fault code information table uploaded by the vehicle diagnostic device for maintenance through the unique vehicle identification code corresponding to the target fault vehicle and the vehicle characteristic information. The vehicle fault code information table is indexed by the vehicle's unique vehicle identification number (VIN) to establish the corresponding vehicle feature information such as vehicle manufacturer, model, year, etc. Then, when the vehicle diagnostic device performs a vehicle fault code scan, it will determine whether the user of the vehicle diagnostic device has the preset fault query permission for the target fault vehicle.

[0040] Step S12: If the user has the preset fault viewing authority, the historical maintenance information of the target fault vehicle is read from the preset fault information table based on the current fault code information, and the vehicle brand fault information corresponding to the target fault vehicle is obtained based on the regional location information.

[0041] In this embodiment, after determining whether the user of the vehicle diagnostic device has the preset fault access authority for the target fault vehicle, it also includes: if the user does not have the preset fault access authority, the fault subscription function is displayed through the preset visual port, so as to remind the user to subscribe to the preset fault access authority through the fault subscription function. That is, if the user does not have the preset fault information table access authority, the diagnosis of the vehicle fault can only be completed by relying on the industry accumulation of the maintenance technician in this industry. Therefore, in this application, the "fault subscription" function service is displayed through the preset visual port, and the user can subscribe to the preset fault access authority. After the user completes the subscription payment, the historical maintenance information of the target fault vehicle is read from the preset fault information table based on the current fault code information, including: based on the unique vehicle identification code of the current fault code information, the target historical fault information of the target fault vehicle and the maintenance plan corresponding to the target historical fault information are read from the preset fault information table. That is, the preset fault information table of the same vehicle (with the same VIN code) can be obtained, including but not limited to the maintenance time, maintenance plan, and maintenance location. The preset fault information table first collects the historical fault information of each faulty vehicle, and classifies and organizes the historical fault information based on the unique vehicle identification code corresponding to each faulty vehicle to obtain the classified historical fault information, and then constructs the preset fault information table based on the classified historical fault information and the maintenance plan corresponding to the classified historical fault information. The acquisition of the vehicle brand fault information corresponding to the target faulty vehicle based on the regional location information includes: obtaining the fault occurrence probability and fault maintenance plan corresponding to the current fault code information of the target faulty vehicle under the regional location information. Specifically, that is, obtaining the percentage of the same brand of vehicles in the area that generate the fault code and the maintenance solution or the ranking information and maintenance plan of the fault code of the same brand of vehicles.

[0042] Step S13: Determine the faulty components and maintenance plan of the target faulty vehicle based on the historical maintenance information and the vehicle brand failure information.

[0043] In this embodiment, the determination of the faulty components and maintenance plan of the target faulty vehicle based on the historical maintenance information and the vehicle brand fault information includes: determining the faulty components and maintenance plan of the target faulty vehicle based on the target historical fault information, the maintenance plan corresponding to the target historical fault information, and the fault occurrence probability and fault maintenance plan corresponding to the current fault code information. That is, after obtaining the target historical fault information, the maintenance plan corresponding to the target historical fault information, and the fault occurrence probability and fault maintenance plan corresponding to the current fault code information, the historical maintenance fault code information of the target faulty vehicle and the frequently occurring vehicle fault conditions according to the regional location information, that is, the percentage of the same brand of vehicles generating the fault code and the maintenance solution or the ranking information and maintenance plan of the same brand of vehicles mentioned in the above steps are used as a reference to determine the components and maintenance plan of the vehicle fault.

[0044] It can be seen that in this embodiment, the current fault code information and regional location information of the target fault vehicle are read by the vehicle diagnostic equipment, and it is determined whether the user of the vehicle diagnostic equipment has the preset fault query authority for the target fault vehicle; if the user has the preset fault query authority, the historical maintenance information of the target fault vehicle is read from the preset fault information table based on the current fault code information, and the vehicle brand fault information corresponding to the target fault vehicle is obtained based on the regional location information; the faulty parts and maintenance plan of the target fault vehicle are determined based on the historical maintenance information and the vehicle brand fault information. In this way, by collecting the historical maintenance information of the target fault vehicle to form a maintenance information table, and combining the vehicle brand fault information that may occur in the vehicle brand under the regional environment as a data reference, the faulty parts of the target fault vehicle can be quickly determined, and a maintenance plan can be generated, thereby reducing the cost and time of vehicle maintenance.
