At present all need the after-sales service technician to utilize traditional hand-held diagnostic equipment to diagnose for automotive electric fault, consult after the parameter that obtains and keep in repair help, operating guidance, data statistics etc. and carry out troubleshooting and maintenance.This has just brought huge challenge to the after-sale service department, maintenance personal's stability, after sale job instruction maintenance and browse the needed time of maintenance direction etc., these problems have restricted the quality and satisfaction of after-sales service; The more important thing is that maintenance personal or service station can't offer the automaker with fault and the relevant information of processing in maintenance process, to help manufacturer to improve.
A kind of novel diagnostic system is provided, and in time the after-sales service personnel being carried out maintenance direction is the problem that prior art need to solve.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of vehicle fault diagnosis system, to reach the purpose of in time the after-sales service personnel being carried out maintenance direction.
For solving the problems of the technologies described above, the technical solution of the utility model is, a kind of vehicle fault diagnosis system, it is characterized in that: described diagnostic system is connected through the internet on automaker's maintenance service device, mantenance data storehouse, technical support terminal for the diagnosis terminal of department after sale, thereby utilize existing Internet technology to realize that the automaker helps the after-sales service personnel to diagnose the purpose of detection, and can comprehensively carry out Data Collection.
Described diagnosis terminal, technical support terminal are common computer.
Described diagnosis terminal is connected on vehicle by the vehicle communication interface.
Described vehicle communication interface is provided with the WiFi module.
A kind of vehicle fault diagnosis system, owing to adopting said structure, this diagnostic system has the following advantages: 1, in time the after-sales service personnel are carried out maintenance direction; 2, facilitate the automaker to carry out fault data collection; 3, utilize existing Internet technology, need not to increase too much cost; 4, make the maintenance personal conveniently, comprehensively search servicing manual, repair information.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail;
Fig. 1 is the structured flowchart of a kind of vehicle fault diagnosis system of the utility model;
In Fig. 1,1, diagnosis terminal; 2, maintenance service device; 3, mantenance data storehouse; 4, technical support terminal.
Embodiment
The utility model is connected through the internet on automaker'smaintenance service device 2,mantenance data storehouse 3,technical support terminal 4 for the diagnosis terminal 1 of department after sale, thereby utilize existing Internet technology to realize that the automaker helps the after-sales service personnel to diagnose the purpose of detection, and can comprehensively carry out Data Collection.
Automaker and after-sale service station combine by the internet like this.The automaker need to configure maintenance helping service device, after sale data management system and technical support department.After-sale service station needs configuration diagnostics terminal 1, comprises the computer that the PC diagnostic software is installed, the vehicle communication interface of integrated WiFi module, diagnosis joint and test wire harness.
The diagnostic function of 1 pair of vehicle of diagnosis terminal.Mainly comprise basic diagnostic trouble code service (the read failure code is removed diagnostic trouble code); Reading data flow; The actuator test; And the specific function of some ECU (Electrical Control Unit) etc.; ECU (Electrical Control Unit) system in automatic identification vehicle, diagnosis terminal 1 is served the identification information that reads ECU (Electrical Control Unit) by diagnosis, and the diagnostic equipment program that automatic selection matches, rather than traditional hand-held diagnostic equipment are by manually going selection.Diagnosis terminal 1 obtains the Part No. of each ECU (Electrical Control Unit), supplier information, after software and hardware version number, confirm the diagnostic software situation of this ECU (Electrical Control Unit), select corresponding diagnostic equipment program, like this when a vehicle is diagnosed, essential information that can each ECU (Electrical Control Unit) of automatic acquisition car load directly shows the diagnostic equipment program of all electric-control systems on the interface of diagnostic equipment.
When maintenance personal's testing vehicle and when obtaining the diagnostic trouble code list, diagnosis terminal 1 can generate a diagnosis report and can upload on automaker'smaintenance service device 2, by the diagnostic data of uploading, the automaker can add up the occurrence frequency of failure code; Diagnosis terminal 1 is according to automaker's requirement, formulate the template of diagnosis report, the information recording/of each vehicle maintenance is got off, after the vehicle maintenance maintenance finishes, automatically generate diagnosis report, be transferred to automaker's mantenance data storehouse according to automaker's the load mode that requires.
In the time of the rear screen display diagnostic trouble code of test, this diagnostic trouble code can be linked to following information: diagnostic trouble code is described, interlock circuit figure, possible failure cause and maintenance suggestion, diagnosis algorithm, terminal/joint location figure etc.;
Wherein the automaker need to set upmaintenance service device 2,mantenance data storehouse 3 andtechnical support terminal 4, automaker's repair information has been stored inmaintenance service device 2 the insides,mantenance data storehouse 3 is to administering and maintaining of data after sale, andtechnical support terminal 4 is responsible for the problem that occurs after sale and is sought help and carry out real-time guidance; The internet mainly provides the network platform, realizes that the automaker is connected connection with after-sale service station; After-sale service station is mainly that the terminal of diagnosis terminal 1 is used department.
The utility model has utilized the powerful local function of PC, except the function that can realize all hand-held diagnostic equipments, increased in addition a lot of expanded functions, such as mantenance data contrast and statistics, diagnosis report generates and patterned human-computer interaction interface etc. automatically; Except above-mentioned local function, the advantage of the utility model maximum has been to utilize powerful internet system, automaker and after-sale service station are combined, realized slitless connection between the two, the automaker can collect by the internet mantenance data of after-sale service station magnanimity, realize remote diagnosis and monitoring, directly after-sale service station is keeped in repair Assistance And Instruction.After-sale service station can directly obtain maintenance Assistance And Instruction data from automaker's database by internet system, and automaker's technical support department is directly linked up etc.
For example, the maintenance personal of after-sale service station is after encountering insurmountable problem, can directly seek help to automaker's technical support personnel by the internet, guidance by the technical support personnel is the investigation of Completion problem more fast and easily, the utility model can generate test report automatically after vehicle is completed maintenance in addition, uploads to automaker's mantenance data storehouse by the internet, avoided allowing the manual record of maintenance personal, waste maintenance personal's working time.
The above is exemplarily described the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subject to the restrictions described above; as long as the various improvement of having adopted technical solutions of the utility model to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
