Method and apparatus for automatically identifying whether OBD car equipment is matched or not through VIN code of passenger car

Abstract

The invention provides a method and an apparatus for automatically identifying whether OBD car equipment is matched or not through a VIN code of a passenger car. The method comprises the steps of creating a car model adaptive table in a database; in the database, extracting VIN codes read by all online car equipment, and writing corresponding fields of the car model adaptive table; when it is judged that OBD data in car equipment codes comprises reported average fuel consumption, judging that the car equipment is matched, and associating 1st to mth bits and pth bit of the VIN code of the car read by the car equipment; when it is judged that the OBD data in the car equipment codes does not comprise the reported average fuel consumption, judging that the car equipment is not matched, and associating the 1st to mth bits and the pth bit of the VIN code of the car read by the car equipment; and receiving a VIN code input instruction of a user, automatically performing comparative matching on the VIN code and the VIN codes of the car model adaptive table, and feeding back and presenting a matching query result to the user. According to the method and the apparatus, whether the OBD car equipment is adaptive to different car models or not can be quickly and effectively queried.

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.
