Method and device for automatically identifying whether obd vehicle and machine match through vin code of passenger car

Abstract

The present invention proposes a method and device for automatically identifying whether the OBD car machine matches through the VIN code of a passenger car, including: creating a car model adaptation table in the database; extracting all VIN codes read by the online car machine from the database, Write it into the corresponding field of the car model adaptation table; when it is judged that the OBD data in the car machine code has reported average fuel consumption, it is judged to be compatible with the car machine, and it is associated with the VIN code 1 to m digits of the vehicle read by the car machine, VIN The p-th digit of the code; when it is judged that the OBD data in the car-machine code does not report the average fuel consumption, it is judged that it is not suitable for the car-machine, and it is associated with the VIN code 1 to m of the vehicle read by the car-machine, and the p-bit of the VIN code ; Receive the user's VIN code input command, automatically compare and match the VIN code with the VIN code in the model adaptation table, and give feedback to the user and present the matching query result. The present invention can quickly and effectively inquire whether the OBD vehicle is compatible with different vehicle models.

Description

technical field [0001] The invention relates to the field of vehicle technology, in particular to a method and device for automatically identifying whether an OBD vehicle is compatible with a passenger vehicle VIN code. Background technique [0002] VIN code is the abbreviation of Vehicle Identification Number, GB 16735-2004 "Road Vehicle Vehicle Identification Number (VIN)" stipulates: VIN code is composed of 17 characters, including the manufacturer, year, model, engine code and assembly location of the vehicle, etc. Information, is the car's identification number. Worldwide, the VIN code uniquely identifies a car. The VIN code begins when a car rolls off the production line, and it is accompanied by the vehicle's registration, annual inspection, insurance, repair, maintenance, used car transactions, and until it is scrapped. [0003] Before consulting and purchasing OBD car products, users often ask whether the product matches their own vehicle. The traditional method r...

However, users often do not know the specific configuration information of their vehicles, and cannot provide effective vehicle configuration information, which often leads to different adaptation results of OBD vehicles on vehicles with different configurations of the same model, which not only affects project cooperation but also increases financial costs.
