Input device and method for vehicle information codes

Abstract

The invention provides an input device and method for vehicle information codes for solving the problem that VIN input equipment low in cost and convenient and fast to use does not exist. The input device comprises OBD interface equipment composed of an OBD end processing chip, an OBD end Bluetooth module, an OBD end interface circuit, an OBD end power source and an OBD end diagnosis interface plug, and mobile handheld equipment composed of a camera module, a mobile end Bluetooth module, a mobile end processing chip, a mobile end storage module, a mobile end human-computer interaction module and a mobile end power source. The input method comprises the steps of building connection between the mobile end processing chip and an engine ECU, building communication between the OBD end processing chip and the mobile end processing chip, recognizing a VIN, writing the VIN in the engine ECU, reading a VIN stored in the engine ECU and checking the VINs. The input device has the advantages of being small in size, low in manufacturing cost, easy to use, high in input efficiency and accurate.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a device and method for entering vehicle information codes. Background technique [0002] According to the GB7258-2012 standard, all passenger cars need to have the function of reading the vehicle information code (VIN) from March 1, 2014. However, the existing production line of the automobile factory does not have the equipment to read and write the vehicle information code (VIN), and cannot automatically input the vehicle information code (VIN) information to the vehicles on the production line, which does not meet the above regulatory requirements. [0003] In order to meet the requirements of the GB7258-2012 standard, the automobile manufacturer may need to add special equipment to the production line and upgrade the diagnostic instrument in the production line control system, and write the vehicle information code (VIN) into the engine ECU of the vehicle, so that the...

Problems solved by technology

[0004] Both of the above two methods have disadvantages: the first method requires the modification and upgrading of the software and hardware of the vehicle production line, and the additional equipment occupies a limited space on the assembly line, which is costly and uneconomical; most automobile manufacturers use the second The second solution is to manually input the vehicle information code (VIN) to the engine ECU of the vehicle through the vehicle diagnostic instrument, which has the outstanding problems of low work efficiency and error-prone. In addition, the vehicle diagnostic instrument is not a special device for inputting information to the engine ECU. , use the vehicle diagnostic instrument for long-term vehicle information code (VIN) entry work, it is easy to shorten the service life of the vehicle diagnostic instrument, the gain outweighs the gain
