Next, the processing process for automobile inspection and diagnosis of the server-type automobile electronic device diagnosis system of the present invention will be described in detail.

FIG. 6 is a flowchart showing a method of operating a server-type automotive electronic device diagnosis system according to the present invention, and FIG. 7 is a flowchart showing a vehicle information search routine using the search algorithm shown in FIG. 6.

Referring to FIGS. 6 and 7, the server-type automobile electronic device diagnosis system 2 of the present invention receives vehicle information of the received inspection target automobile 10 when the automobile inspection machine 200 inspects the automobile in step S500. . As another example, the automobile inspection device 200 may receive vehicle information of the inspection target automobile 10 received from the inspection management server 300. Here, vehicle information includes the vehicle's registration number, vehicle identification number, production year, model, vehicle name, motor type, axle-to-axle distance, and passenger capacity.

In step S510, in order to determine the car by checking the vehicle information of the car 10, the car tester 200 searches the car information using a search algorithm. At this time, the vehicle 10 subject to inspection includes a vehicle manufactured by the original manufacturer, a specially equipped vehicle purchased from the original manufacturer and modified for a special purpose, and a high-power electric device such as an electric vehicle, a hybrid vehicle, a hydrogen fuel cell vehicle, etc. This includes cars, etc. Therefore, the automobile inspection device 200 determines the automobile 10 to be inspected through vehicle information.

In this embodiment, the vehicle information search routine (S510) using a search algorithm, as shown in FIG. 7, determines that the vehicle 10 received for inspection in step S520 is a specially equipped vehicle if the vehicle information is not the vehicle information of the original manufacturer. . That is, if the automobile 10 that has been accepted for inspection is a specially equipped vehicle, this procedure proceeds to step S534 and the specifications of the automobile are analyzed using the input vehicle information, that is, the specifications information of the specially equipped vehicle. At this time, in steps S534 to S542, the vehicle type, engine type, chassis number, production year, and axle distance are sequentially searched, and in step S544, the original manufacturer's vehicle information matching the vehicle information of the specially equipped vehicle is automatically extracted and selected. Then, the process proceeds to step S522, where the vehicle is determined through vehicle information of the selected original manufacturer. That is, in steps S522 to S530, vehicle classification, vehicle model, production year, fuel, and engine displacement are sequentially classified, and through this, diagnostic data for the specially equipped vehicle is automatically selected in step S532 based on the vehicle information of the original manufacturer.

However, if the vehicle information of the automobile 10 received for inspection in step S520 is the vehicle information of the original manufacturer, the automobile inspection machine 200 determines it to be a general automobile and sequentially classifies the automobile, vehicle model, and year of manufacture in steps S522 to S530. , fuel type and displacement are classified, and through this, diagnostic data about the vehicle information of the original manufacturer is automatically selected in step S532.

Referring again to FIG. 6, in step S510, the car inspector 200 determines the car 10 to be inspected in step S550 according to the result of searching the vehicle information, and performs a diagnosis corresponding to the car 10 determined in step S560. Data is requested and downloaded from the test management server 300.

When diagnostic data is transmitted from the inspection management server 300 in step S570, the automobile tester 200 uses the diagnostic data to inspect and diagnose the status of various electronic devices of the automobile 10, and provides inspection result data in step S580. It is displayed so that it can be checked and transmitted to the test management server 300.

Subsequently, in step S580, the automobile tester 200 deletes the diagnostic data and test result data so that only the test management server 300 manages test-related data.

In the above, the configuration and operation of the server-type automotive electronic device diagnosis system and its operating method according to the present invention have been shown in detail and illustrated in accordance with the drawings, but this is merely an example and does not depart from the technical spirit of the present invention. Various changes and modifications are possible within the scope not specified.
