Abstract

The invention is suitable for the technical field of an automobile and provides an automobile vehicle identification number write-in method and device. The method comprises the following steps: a power supply of the automobile is connected to start an electronic control unit assembled on the automobile; the electronic control unit generates a vehicle identification number obtaining request and sends the vehicle identification number obtaining request to a vehicle control unit of the automobile; the vehicle control unit obtains pre-written vehicle identification number from a first storage device, and returns the obtained vehicle identification number to the electronic control unit; and the electronic control unit writes the received vehicle identification number into a second storage device to realize vehicle identification number writing of the electronic control unit, so that after the automobile electronic control unit is assembled and powered on, the vehicle identification number can be obtained from the first storage device in the vehicle control unit automatically and written into the electronic control unit to finish automatic vehicle identification number obtaining and writing of the electronic control unit, and vehicle identification number writing efficiency of the electronic control unit is improved.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a method and a device for writing a vehicle identification code of an automobile. Background technique [0002] During the production process of a car, some or most of the different electronic control units (Electronic Control Unit, ECU) on the car may use the vehicle identification number (Vehicle Identification Number, abbreviated as VIN) code, and the existing car VIN code writes The method is: according to the VIN code printed on the car body, the automobile production workers manually input the VIN code into the diagnostic instrument and check it clearly. Writing reduces the production efficiency of the car to a certain extent. Contents of the invention [0003] The object of the present invention is to provide a vehicle identification code writing method and device, aiming to solve the problem that the vehicle identification code writing process is cumber...
